Earthquakes are caused by the movement of tectonic plates underneath the earth's surface. When the plates shift and release stress, seismic waves propagate outward from the epicenter. Scientists measure the intensity of earthquakes using the Richter scale. During an earthquake, it is important to drop, cover, and hold on underneath sturdy furniture to protect oneself from falling debris.

Earthquake and its causes
Earthquake is a tragedy to life and property. Here its possible causes , effects and hazards they cause are discussed.
Earthquakes
Earthquakes occur when stress builds up in Earth's crust along fault lines, causing rocks to fracture and slip past each other. There are three main types of faults - strike-slip, normal, and reverse - which form due to different types of stress. When fault slippage occurs, it releases seismic waves that radiate outward. Seismographs can detect these waves and use their properties to determine the earthquake's location, magnitude, and type of fault movement. Major earthquakes pose a threat through ground shaking and secondary effects like fires, landslides, and tsunamis that can damage infrastructure and endanger human lives.
Types and causes of earthquakes
This is a powerpoint which explains the types of seismic waves that earthquakes create and the causes of earthquakes in the first place.
Earthquake ppt
1) Earthquakes are caused by the sudden release of energy from movement along geological faults in the earth's crust, generating seismic waves.
2) Larger earthquakes can trigger tsunamis if located offshore by displacing seabed, as well as landslides and volcanic eruptions.
3) Earthquake shaking causes loss of life and property destruction from building collapse and landslides burying infrastructure.
Earthquakes
An earthquake is a sudden, rapid shaking of the Earth caused by the breaking and shifting of rock beneath the Earth's surface, which creates seismic waves. There are two main types of seismic waves: P-waves and S-waves. Earthquakes are caused by the buildup and sudden release of stress in the Earth's crust, which generates vibrations that travel through the Earth's interior and surface as seismic waves. Major earthquakes can cause significant damage through shaking, ground ruptures, landslides, fires, tsunamis, and floods.

Causes and Effects of Earthquakes
Earthquakes are caused by slow movements within the Earth as it continues to cool. Some human activities like constructing dams, extracting groundwater, fracking, and building skyscrapers can also induce earthquakes by adding stress that destabilizes existing faults. Earthquakes have both primary effects of immediate damage through collapsing buildings, and secondary effects like tsunamis, landslides, fires, disease outbreaks, and soil liquefaction that prolong suffering after the initial quake.

Tsunami
Tsunami are powerful waves created by earthquakes, volcanic eruptions, or landslides that displace large volumes of water. They can reach heights over 30 meters and speeds over 700 km/hr, destroying everything in their path. The devastating 2004 Indian Ocean tsunami killed over 118,000 people across several countries, displaced millions, and caused widespread damage to infrastructure and the environment. Relief efforts provided temporary housing, food, water and medical aid to victims, but recovery is a long process and many remain in need of support years later.
Tsunami Notes
Tsunamis are large destructive waves caused by geological events such as earthquakes, volcanoes, or landslides that displace large volumes of water. They are most commonly triggered by earthquakes of magnitude 7.0 or higher where the epicenter is located near or below the ocean. When the ocean floor is suddenly displaced by one of these events, it generates a series of long wavelength waves that propagate outward from the source. As these waves enter shallower coastal waters, their speed decreases and wavelength and height increase, sometimes resulting in a massive flooding wave that can cause devastating damage when it reaches land.
Earthquakes
The document discusses earthquakes, including their causes, types, effects, and measurement. Earthquakes are caused by the sudden release of stress along faults within the earth's crust. They can be shallow, mid-focus, or deep, and cause both primary (P) waves and secondary (S) waves. The magnitude and intensity of quakes are measured using the Richter scale and Mercalli scale, respectively. Major quakes frequently occur at plate boundaries and have caused widespread damage throughout history.

The document outlines safety rules both before, during, and after an earthquake to minimize injury.
Tsunami ppt.pptx
This document provides information about tsunamis, including what causes them, how to recognize warning signs, and safety steps to take before, during, and after a tsunami occurs. It advises people living near coastal areas to be aware of evacuation routes and plans, know their street's elevation and distance from the coast, and prepare families on how to turn off utilities and contact emergency services. The goal is to help reduce loss of life and damage from potential future tsunamis.
Causes, Effects and Precautions against Earthquake
1. Earthquakes are caused by the movement of tectonic plates deep below the Earth's surface. As the plates shift and grind against each other, they release energy in the form of seismic waves.
2. Major earthquakes can cause widespread damage to infrastructure like buildings, bridges and dams, resulting in loss of life and property. They can also trigger secondary hazards such as landslides, tsunamis and fires.
3. Pakistan is prone to earthquakes, with major fault lines running along its western border. Some of the deadliest quakes in the country's history include the 2005 Kashmir earthquake that killed over 80,000 people and the 2013 Balochistan earthquake that killed 825.
Geological disasters

For each disaster type, the document outlines key factors like the mechanisms that trigger them, methods for predicting events, and international or local responses to past incidents. The overall document serves as an informative guide to common geological hazards and considerations for minimizing risks.
Tsunami
Geography students can play an important role in disaster management for tsunamis. They can help with preparedness by creating maps of vulnerable areas, raising community awareness, and developing evacuation plans. During a tsunami, they can assist with search and rescue efforts, first aid, and ensuring access to food and water. In recovery, geography students aid with tasks like debris cleanup, infrastructure rebuilding, and counseling. Overall, they contribute to reducing future impacts through activities like hazard identification, early warning systems, and public education.
What Causes Earthquakes?
This document describes different types of faults and what causes earthquakes. It explains that normal faults occur due to tension and drop one side down, while thrust faults occur due to compression and raise one side up. Strike-slip faults cause the sides to scrape past each other due to shearing. Earthquakes are caused when plates get stuck and release energy in sudden jerks, sending out seismic waves from the focus. The epicenter is where the waves reach the surface above the focus.
Earthquakes - It's Causes And Effects
Earthquakes are caused by movements within the earth's crust or volcanic action. There are several types of earthquakes including tectonic, volcanic, collapse, and explosion earthquakes. Tectonic earthquakes occur due to geological forces on rocks and plates, volcanic earthquakes are induced by movement of magma, collapse earthquakes happen in underground mines and caverns, and explosion earthquakes result from nuclear or chemical explosions. Earthquakes are a natural result of the earth cooling, but human activities like dams, groundwater extraction, geothermal plants, and injection wells can also induce quakes. Earthquakes cause both primary effects like collapsed buildings that kill people directly, and secondary effects like tsunamis, landslides,

Landslide
This document discusses geological hazards caused by landslides. It defines landslides as the downward sliding of land mass along steep slopes due to gravity. Heavy rains, earthquakes, floods, terrain cutting and droughts are among the main causes. Different types of landslides are described such as rock falls, lahars, earthflows, slope failures, slumps and debris slides. Areas with steep slopes, volcanoes, coasts and river valleys are prone to landslides. Landslides can damage infrastructure and block traffic. Classification, prevention measures and examples of landslide disasters are also summarized.
Earthquakes
Earthquakes occur along plate boundaries due to the buildup and sudden release of energy from shifting tectonic plates. When plates lock, potential energy builds until released as seismic waves that propagate outward from the earthquake focus. Most earthquakes occur along oceanic and continental plate edges or along faults like normal, reverse, and transform boundaries. P and S waves are the primary seismic waves, with P waves traveling faster and S waves causing the shaking felt during quakes. Earthquake magnitude measures the energy released using the Richter scale, while intensity qualitatively describes the shaking effects on a place using the Mercalli scale.

Earthquakes ppt for class
This is the earthquake power point you saw in class. Feel free to take notes on it or view the animations again.
Earthquake Animation
An earthquake occurs when tectonic plates beneath the earth's surface suddenly move, releasing seismic waves. Earthquakes can cause significant damage through shaking and displacement of the ground, sometimes triggering tsunamis that lead to loss of life and destruction of property. The interactive animation teaches about earthquakes and what to do during one, such as evacuating buildings via emergency stairs or taking shelter under sturdy furniture if unable to exit. The objective is to use the knowledge provided to stay safe in an earthquake scenario.
Earthquake Notes Summary
Earthquakes are caused by the sudden release of built-up energy along fault lines in the earth's crust. They begin at a focal point below the surface and radiate seismic waves outward. The location directly above the focus on the earth's surface is called the epicenter, which is important for understanding where damage and shaking will be strongest. Earthquakes are measured on the Richter scale, which quantifies the amount of energy released. Areas near fault lines are more susceptible to earthquakes, and the severity of shaking and damage depends on the quake's magnitude, distance from the epicenter, and local geology.
Earthquake preparedness ppt
This document provides information about earthquake preparedness and safety. It defines earthquakes and aftershocks, lists associated hazards like fires and landslides, and notes increasing earthquake activity in San Diego County. It offers tips for being prepared like securing heavy objects, identifying safe places to take cover, learning how to shut off gas, and developing a communication plan. Specific guidance is given on checking for hazards, using safe positions during shaking, what to do after an earthquake like checking for fires and injuries, and activating emergency plans. Interactive elements test the reader's knowledge of identifying hazards and safe positions to take during an earthquake.
Disaster management ppt
Disaster management involves dealing with and avoiding both natural and man-made disasters through preparedness, response, recovery, and mitigation efforts. It aims to reduce vulnerabilities and impacts through organized and sustained actions to analyze and manage hazards and the underlying risks. Key aspects of disaster management include preparedness before a disaster through activities like risk assessment, warning systems, and stockpiling resources; immediate response efforts during an event; and long-term rehabilitation and reconstruction work after an event to support regrowth. Effective disaster management requires coordination and planning across different levels of government, organizations, and communities.

Earthquake
Earthquakes are caused by the movement of tectonic plates in the earth's crust. When the plates move and build up stress, they suddenly break, causing seismic waves that create shaking at the earth's surface. Scientists study plate tectonics and faults to better understand earthquake mechanisms. Safety tips during quakes include dropping under sturdy furniture, covering your head, and holding on until shaking stops. Earthquakes can trigger dangerous tsunamis by displacing large volumes of water.
Earthquake
Earthquakes are caused by the movement of tectonic plates underneath the Earth's surface. When the plates squeeze or stretch against each other and build up stress, they can suddenly break, releasing energy in the form of seismic waves that cause the shaking we experience during earthquakes. Faults occur at boundaries between the plates where rocks have fractured. Plate tectonics describes the slow drifting and interaction of these massive plates over geological timescales.
Earthquake presentation
Earthquakes occur when tectonic plates squeeze or stretch and release stress energy in the form of seismic waves. Scientists are working to predict earthquakes but currently they cannot be predicted. The epicenter is the point where the earthquake originates and seismic waves radiate out strongest. The Richter scale is used to measure an earthquake's intensity on a logarithmic scale with each whole number increase representing a tenfold increase in amplitude. Safety tips recommend dropping under sturdy furniture, covering your head and holding on during shaking, and checking for hazards after shaking stops.
Earthquake
Earthquakes are caused by the movement of tectonic plates deep underground. When the plates squeeze or stretch against each other, they build up stress until the rocks suddenly break or shift, releasing energy in the form of seismic waves. Faults occur at boundaries where the plates meet and rocks on either side slip past one another. There are several major types of faults defined by how the rocks move. Plate tectonics theory explains that the Earth's crust is made up of plates that move at different rates in various directions, sometimes colliding or sliding past each other, causing earthquakes. The intensity of earthquakes is measured on the Richter scale, with each whole number increase representing a tenfold increase in amplitude.
Earthquake presentation
Earthquakes are caused by the movement of tectonic plates underneath the earth's surface. When the plates squeeze or stretch against each other, they build up stress until the crust breaks, releasing energy in waves that cause the shaking we feel. There are four major types of faults where the broken rocks of the earth's crust slide past each other. Scientists use seismographs to measure and record earthquakes to help understand seismic activity and work on predicting quakes, although they cannot be predicted with complete accuracy currently.
Earthquake
Earthquakes are the shaking, rolling or sudden shock of the earth’s surface. They are the Earth's natural means of releasing stress. Earthquakes can be felt over large areas.
Earthquakes cannot be predicted, although scientists are working on it.
EARTHQUAKES AND FAULTS
The document discusses earthquakes and how they occur. It explains that earthquakes are caused by sudden movement along faults in the Earth's crust due to a build up of stress. There are three main types of faults - normal, reverse, and strike-slip - each forming in a different way due to tension or compression in the crust. When friction along a fault is overcome, the fault will slip and move, causing seismic waves that produce shaking during an earthquake. The intensity of shaking and damage decreases further from the earthquake's epicenter.

1. Magnitude measures the energy released at the earthquake source using seismograph measurements, while intensity measures the strength of shaking felt at a location.
2. Earthquake hazards include ground shaking, surface rupture, liquefaction, tsunamis, and landslides. Ground shaking is caused by the release of built-up stress in the lithosphere.
3. To escape a tsunami, immediately evacuate areas near the shore if a large earthquake occurs offshore. Bring a survival kit and head to designated evacuation centers or high ground, staying alert for waves, floods, and landslides.
Earthquakes
1. The document discusses earthquakes and faults, explaining that the Philippines is prone to earthquakes due to its location along the Ring of Fire.
2. It defines a fault as a break in the earth's crust where significant movement has occurred, and explains how faults produce earthquakes through the buildup and sudden release of energy from inside the earth.
3. The document provides information on earthquake waves, intensity scales, and safety tips for both indoors and outdoors during and after an earthquake.

Earthquakes are caused by the sudden release of built-up energy in the Earth's crust. When tectonic plates or blocks of rock underground break along faults, seismic waves propagate, causing the shaking we experience during earthquakes. The location of the initial rock break is called the focus, while the point directly above on the surface is the epicenter. Earthquake intensity and magnitude characterize the severity and size of the shaking respectively. Proper preparation and following safety procedures during and after quakes can help minimize harm.
Disaster
The document discusses earthquakes and provides information about their causes, characteristics, and effects. It defines an earthquake as the sudden movement of the Earth caused by the sudden release of stored energy over long periods of time. It notes that earthquakes originate from a hypocenter inside the Earth's crust and are most intense at the epicenter on the surface. Examples of major earthquakes in Panama are provided. Advice is given about preparing for, responding safely to, and recovering from earthquakes.
EarthQuake
1) Earthquakes occur due to the constant movement of tectonic plates inside the Earth. As strain builds up along fault lines where plates meet, it is suddenly released in the form of seismic waves.
2) The Richter scale is used to measure the magnitude of earthquakes based on the energy released. Major earthquakes over magnitude 7 can cause widespread damage.
3) To prepare for earthquakes, families should identify safe spots in each room, hold regular earthquake drills, and secure heavy furniture and objects that could cause injury. Being prepared is important since earthquakes provide no warning.
Earthquake
The document provides information about earthquakes, including:
- Earthquakes are caused by the sudden release of energy from movement within the earth's crust. This movement occurs along faults.
- Seismic waves travel outward from the earthquake epicenter/focus. There are two main types of seismic waves - body waves and surface waves. Body waves arrive first and can travel through solid earth, while surface waves cause the most damage.
- Seismographs create seismograms to measure and record earthquake seismic wave activity. Proper preparation and safety measures can help reduce risks during earthquakes.
Earthquake: A Tragedy to life and property
An earthquake is the shaking of the Earth's surface caused by a sudden release of energy in the Earth's lithosphere. This social science project discusses earthquakes, including what they are, their causes, effects, and protection against them. Some key points made are that earthquakes result from the movement of tectonic plates and built-up pressure being released. Their effects include ground shaking, ground ruptures, landslides, tsunamis, and fires. Protection involves earthquake-resistant building construction and safety precautions during shaking. Some of the deadliest earthquakes mentioned caused thousands of deaths, such as in Nepal in 2015 and Japan in 2011.
E A R T H Q U A K E S
An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves. Faults are fractures in rock where one side has moved relative to the other. Seismic waves, detected by seismographs, include P-waves, which are longitudinal, and S-waves, which are transverse. Surface waves travel near the Earth's surface and can be the most destructive. The magnitude of most quakes is measured on the Richter scale invented in 1934 by Charles Richter. During quakes, it is safest to drop, cover, and hold on until the shaking stops.
Earthquake
This document provides information about earthquakes, including what causes them, different types of faults, seismic waves, measuring earthquake intensity, effects of earthquakes, and preparedness and response. It explains that earthquakes are caused by a sudden slip along a fault due to built up stresses in the earth's crust. There are three main types of faults - strike-slip, thrust, and normal - depending on the type of plate motion and rock. When an earthquake occurs, seismic waves are generated including body waves (P and S waves) and surface waves (Love and Rayleigh waves). Earthquake intensity can be measured using the Mercalli scale or Richter magnitude scale. Earthquakes can cause damage through ground shaking, landslides
Earthquakes
1) Earthquakes are caused by the sudden release of energy in Earth's crust from tectonic plate movement.
2) Seismic waves from earthquakes travel outward from the focus, with P and S waves detected by seismographs to locate the epicenter.
3) The magnitude scale is used to measure earthquake strength based on seismic wave amplitude, while intensity scales describe damage levels at a location.
Earthquake Notes
Earthquakes occur when tectonic forces cause rocks underground to break, releasing seismic waves. The focus is where the rocks break, and the epicenter is the point directly above on the surface. Different types of faults are caused by tension, compression, and shear forces. Earthquakes are measured by their magnitude using the Richter scale and by their intensity of shaking. Locating the epicenter involves measuring seismic wave arrival times at different stations. Earthquake dangers include falling objects, fires, tsunamis, liquefaction, and landslides.
Earthquakes and Volcanoes
An earthquake occurs when stress on a fault overcomes friction, causing the plates to slip and release energy in waves. The focus is the underground origin, directly above which is the epicenter where shaking is most intense. Magnitude measures energy released, with each whole number indicating 10 times greater energy release. A seismograph records ground vibrations from seismic waves, distinguishing P and S waves. Volcanoes form when pressure builds from magma and erupts, sometimes continuously, sometimes explosively, posing devastation from ash and flows. They are classified as active, dormant, or extinct based on recent eruption patterns, mostly occurring in three zones of tectonic plate movement.
Earth Quake
The document provides information about earthquake hazards and safety. It discusses the interior structure of the Earth including the crust, mantle, outer core, and inner core. It explains what causes earthquakes, noting they occur on faults when the blocks of rock on either side slip past one another. It emphasizes the importance of having an emergency plan and kit in case an earthquake occurs, including how to shut off gas, water, and electricity. Safety tips are provided about what to do during and after an earthquake.

Crystals
The document discusses crystals and their properties. It notes that Nicolaus Steno first observed in 1669 that the angles between surfaces of crystals are always exactly 90 degrees. It explains that crystals are made up of small repeating units arranged in a pattern. There are seven crystal systems defined by the lengths of the unit cell axes and the angles between them.
A letter from hell
A man writes a letter to his mother from hell, describing the unimaginable suffering he endures in endless darkness, pain, fear and torment. He regrets ignoring warnings from preachers about turning from sin, and now understands Jesus suffered to save him from this fate, though it is too late for repentance. He begs his mother to warn his brothers that bravado means nothing in hell, where the only memories are of opportunities squandered and a foolish life lived without God.
Work And Simple Machines
Work is defined as a force applied to an object, moving it a distance. Simple machines like levers, pulleys, and inclined planes make work easier by multiplying applied forces or distances moved. They provide mechanical advantages but also lose efficiency due to friction. Common simple machines are described along with their applications, mechanical advantages, and efficiency considerations.
Simple Machines
Simple machines include wheels and axles, pulleys, inclined planes, wedges, screws, and levers. They have few moving parts and make work easier by changing either the size or direction of force. Wheels and axles allow rotation, pulleys use grooved wheels and ropes to transmit force, and inclined planes lower the amount of force needed to lift an object. Levers come in three classes depending on the position of the fulcrum and load. Simple machines can be combined to create more complex machines.
Mechanical Advantage Of Machines
Mechanical advantage refers to the number of times a machine multiplies force. There are two types: theoretical mechanical advantage (TMA), which considers distances moved; and actual mechanical advantage (AMA), which considers applied and produced forces. Efficiency is the ratio of output work to input work, and is less than 100% due to friction converting some input work to heat. Sample problems demonstrate calculating TMA, AMA, efficiency, effort, and work input using relevant equations.
Igneous And Magma
The rock cycle document describes the three main types of rocks - igneous, sedimentary, and metamorphic - and how they are related through geological processes. It focuses on igneous rocks, which form from cooling magma, and can cool underground to form intrusive rocks or above ground to form extrusive rocks like lava. The composition and cooling rate of magma determines the type of igneous rock formed. Magma is hot melted rock from deep in the Earth, and its viscosity is affected by temperature and silica content.
How To Pray The Rosary

https://bit.ly/35n5P0e
The Rosary is one of the most beloved and distinctive Roman Catholic prayers. The prayer has a long tradition in history, but is remarkably modern, at least by Catholic standards.
"Realize the power in your hand with the Rosary, for in your hands you hold the power of God. If you do not recognize the Rosary, can you expect to be recognized by My Son? How much can you expect? Why do you hide My Rosary? It was with a Mother's loving heart that I chose to give you these pearls of Heaven that you reject.
"Woe to all dedicated who seek to remove these from the little ones' hands, for their punishment will be metered in accordance to it!
"Why has sophisticated man cast aside these tokens of My love? Those who remain true to My Rosary will not be touched by the fires. Gather these treasures, My children, for the time will come that you will not find them on the counters of your stores." - Our Lady of the Roses, October 6, 1970.

This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Earthquake Presentation
- 1. Earthquake Presented by:ryan ali m. catagaI-faith
- 2. Earthquakes are the shaking, rolling or sudden shock of the earth’s surface. They are the Earth's natural means of releasing stress. Earthquakes can be felt over large areas although they usually last less than one minute. Earthquakes cannot be predicted, although scientists are working on it.
- 3. There are about 20 plates along the surface of the earth that move continuously and slowly past each other. When the plates squeeze or stretch, huge rocks form at their edges and the rocks shift with great force, causing an earthquake. Ex: pencil test
- 4. As the plates move they put forces on themselves and each other. When the force is large enough, the crust is forced to break. When the break occurs, the stress is released as energy, which moves through the Earth in the form of waves, which we feel and call an earthquake.
- 5. A fault is an area of stress in the earth where broken rocks slide past each other, causing a crack in the Earth's surface. There are 4 major types of faults which are as follows: dip-slip normal, dip-slip reverse, strike-slip, and oblique-slip.
- 8. Strike - Slip Fault
- 9. Oblique - Slip Fault
- 10. The plate tectonic theory is supported by a wide range of evidence that considers the earth's crust and upper mantle to be composed of several large, thin, relatively rigid plates that move relative to one another.
- 11. The plates are all moving in different directions and at different speeds. Sometimes the plates crash together, pull apart or sideswipe each other. When this happens, it commonly results in earthquakes.
- 12. A seismograph is an instrument used for recording the intensity and duration of an earthquake.
- 13. A tsunami is a large ocean wave usually caused by an underwater earthquake or a volcanic explosion. Tsunamis are NOT tidal waves. Tidal waves are caused by the forces of the moon, sun, and planets upon the tides, as well as the wind as it moves over the water. With typical waves, water flows in circles, but with a tsunami, water flows straight. This is why tsunamis cause so much damage.
- 14. Tidal waves vs. Tsunamis tidal waves tsunamis
- 15. Important Terminologies: EPICENTER - The point on the earth's surface directly above the source of the earthquake. SEISMIC WAVES - The energy created by the quake that travels in waves from the epicenter, where they are the strongest.
- 16. RICHTER SCALE - A measurement of an earthquake's intensity. - Each one-point increase on the scale indicates ten times the amount of shaking and 33 times the amount of energy. - The energy released by a large earthquake may be equal to 10,000 times the energy of the first atomic bomb.
- 17. Richter Scale 4 - Minor Earthquake 5 - Moderate Earthquake 6 - Strong Earthquake 7 - Major Earthquake 8 - Great Earthquake
- 20. Stay indoors until the shaking stops.
- 21. Stay away from windows.
- 22. If you’re in bed, hold on and stay there, protecting your head with a pillow.
- 23. If you’re outdoors, find a clear spot away from buildings, trees and power lines. Then, drop to the ground.
- 25. Inspect your home for damage.
- 26. Eliminate fire hazards, so turn off the gas if you think its leaking.
