Edu 290 powerpoint part 1
This document lists and briefly describes several natural disasters: avalanches which occur when large amounts of snow travel down a slope powered enough to damage trees and buildings; earthquakes which happen along fault lines when tectonic plates shift; hurricanes which are tropical cyclones with strong sustained winds; landslides and mudslides which involve the rapid movement of earth and debris; tornadoes which feature rotating columns of wind; tsunamis which are large sea waves caused by earthquakes or volcanic eruptions; and volcanoes which erupt when magma and gases are released from the earth's crust.
natural disaster
This document discusses 5 types of natural disasters: floods, volcanoes, earthquakes, tsunamis, and tornadoes. It provides more details about earthquakes, explaining that they are usually caused by the sudden breaking of rock underground along a fault, releasing energy that causes seismic waves and shaking. Tsunamis are described as waves caused by sudden movements of the ocean due to earthquakes, landslides, volcanic eruptions, or meteorite impacts. Tornadoes are defined as tubes of violently spinning air that touch the ground, making them very dangerous due to their fast winds.
Severe weather thunderstormandtornado
Thunderstorms form when warm, humid air rises rapidly and condenses into clouds. Lightning results from a buildup of positive and negative charges within storm clouds and between clouds and the ground. Thunderstorms can also spawn tornadoes if wind shear is present. Most tornadoes are relatively small and short-lived, but the most intense can completely demolish buildings.
Disaster management
This document provides summaries of different types of natural disasters:
- Droughts occur in virtually all climates and are second only to hurricanes in economic impacts in the US.
- Earthquakes can range from small to large, with large ones capable of destroying buildings and causing deaths and injuries.
- Floods occur when a river or other body of water receives too much water, overflowing its normal path onto dry land in a flash or due to other events like tsunamis or large storms.
- Tsunamis are generated by underwater disturbances like earthquakes, volcanic eruptions, explosions, landslides, meteor impacts that displace large volumes of water.

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.

This document discusses the top 11 natural disasters: landslides, floods, thunderstorms, tsunamis, volcanic eruptions, droughts, hurricanes, tornadoes, wildfires, earthquakes, and avalanches. It provides details on the causes and impacts of each type of disaster, with landslides defined as the movement of land down a slope by gravity, floods caused by excessive rainfall, and tsunamis generated by displacement of large bodies of water. The document aims to raise awareness of natural hazards and inform readers on disaster preparedness.
Earthquakes
Earthquakes occur along fault lines as a result of tectonic plate movement and built up stress being released. They can cause significant damage depending on their magnitude, proximity to populated areas, and local soil and construction practices. Major earthquake zones exist along plate boundaries where tectonic plates converge, diverge, or move past each other. The largest, most destructive quakes occur in subduction zones. To minimize earthquake risk, communities can educate citizens, construct earthquake-resistant buildings, and implement emergency planning and insurance.

Earthquake
1) An earthquake is caused by a sudden release of energy in the earth's crust that creates seismic waves. 2) There are different types of seismic waves including P waves, S waves, Love waves, and Rayleigh waves that move in different motions. 3) The epicenter of an earthquake can be located using data from at least 3 seismic stations to determine where the P and S waves intersect. 4) Major earthquakes can cause widespread destruction and loss of life depending on their magnitude and proximity to populated areas. 5) Common effects of earthquakes include damage to infrastructure, disruption of basic services, loss of life and property, and economic impacts.

Seismographs record earthquake events. Where Do Earthquakes Occur and How Often? What are the Destructive Effects of Earthquakes? How are the Size and Strength of an Earthquake Measured? Can Earthquakes be Predicted? Can Earthquakes be Controlled?
Endogenous disasters
Endogenous hazards such as earthquakes and volcanoes are caused by processes inside the Earth. Earthquakes occur along fault lines as tectonic plates shift and release built-up pressure. The magnitude is measured by the Richter scale. Volcanoes form at plate boundaries as magma works its way to the surface. There are different types of volcanoes classified by their shape that can have explosive or effusive eruptions. Plate tectonics theory explains how the movement of plates causes earthquakes and volcanic activity at plate boundaries.
Earthquake and its impact
The key factors that influence how hazardous an earthquake can be are:
1. The magnitude of the earthquake, with larger earthquakes causing more damage.
2. The distance from the earthquake's epicenter, with those closer experiencing greater shaking.
3. The population density of the affected area, increasing risks to human life and infrastructure in more populated locations.
4. The level of preparedness, as damage is reduced when populations have taken measures to prepare for earthquakes.
Endogenous disasters earth quakes
An earthquake (also known as a quake, tremor or temblor) is is the shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to the people around and destroy whole cities.
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.
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,
Plate Tectonics Photographic Evidence - QiHua
1) There are several types of plate boundaries including convergent boundaries where plates collide and form mountains, divergent boundaries where plates separate and form rift valleys, and transform boundaries where plates slide past each other causing earthquakes.
2) Earthquakes occur when rocks underground suddenly break along a fault line. Major earthquakes can cause extensive damage to infrastructure and loss of life. They also sometimes trigger tsunamis.
3) Tsunamis are large sea waves caused by earthquakes or other seismic events under the sea. The 2011 tsunami in Japan was triggered by a powerful earthquake and resulted in over 3,000 deaths as well as nuclear radiation leaks.
Causes of earthquakes....
This document discusses different types of earthquakes. It defines key terms like focus, hypocenter, and epicenter. Earthquakes are classified by depth of focus into shallow, intermediate, and deep. They are also classified genetically into tectonic and non-tectonic. Tectonic earthquakes result from rock deformation during mountain building and make up the majority. They are caused by elastic rebound, sudden shearing during plastic flow, and folding. Non-tectonic include volcanic quakes from magma movement and impact quakes from explosions or meteorite impacts.
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
Effects of earthquake and tsunami
The document discusses earthquakes and tsunamis, their causes and effects. Earthquakes are caused by shifting tectonic plates and can damage structures, cause landslides and flash floods. Tsunamis are large sea waves typically caused by underwater earthquakes that can damage property, cause flooding and loss of life. The document recommends remedies like responsible planning, seismic retrofitting and high seawalls to minimize damage from these disasters.
Natural disaster
1) A natural disaster is defined as a natural hazard that causes significant financial and human losses through its impact on the environment. Examples include floods, earthquakes, tsunamis, and epidemics.
2) Natural disasters occur when natural hazards intersect with vulnerabilities in human systems. Major causes are seismic activity, soil erosion, and the greenhouse effect.
3) Natural disasters can be categorized as either hydrometeorological, involving atmospheric/hydrological phenomena like floods and storms, or geological, involving earthquakes, tsunamis and landslides.
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.
Natural disasters
The document discusses several natural disasters including tsunamis, volcanoes, hurricanes, droughts, and earthquakes. It provides definitions and descriptions of each phenomenon. Tsunamis are large waves caused by undersea earthquakes or landslides that can reach heights of 30 meters. Volcanoes form when molten rock rises from below the surface due to tectonic plate movement, and can cause additional disasters when erupting. Hurricanes are large storms formed over warm ocean waters that rotate anti-clockwise and contain strong winds. Drought occurs when a long period passes without rain, preventing crop growth. Earthquakes are sudden releases of stress in the Earth's crust that cause shaking.
3JHaines
This document discusses various types of clouds and precipitation. It explains that clouds form through processes like adiabatic cooling, orographic lifting, and frontal wedging. Clouds are classified by height as high, middle, or low clouds. Precipitation occurs through warm cloud processes like collision-coalescence or cold cloud processes like the Bergeron process. Other types of precipitation include rain, snow, sleet, glaze and hail. Fog is also discussed as a cloud at ground level.

Tectonics preparedness slides
Fold mountains form along convergent plate boundaries where rock layers are compressed and fold upwards. Major fold mountains include the Rocky Mountains, Himalayas, and Alps. Rift valleys form along divergent boundaries as the plates pull apart, causing the land between them to drop down. Block mountains occur when sections of crust are pulled apart, leaving blocks behind with steep sides. Volcanoes form at divergent and convergent boundaries, with magma building shield volcanoes with gentle slopes or composite volcanoes with layered eruptions. Earthquakes occur along fault lines as tectonic plates slip past each other, potentially causing damage over large areas through shaking, tsunamis, fires, landslides and infrastructure disruption.

Landforms on the earth
The physical environment chapter discusses the components that make up Earth's physical environment: land, air, water, and the living environment. It describes key landforms like mountains and rivers, as well as geological processes that create and modify landforms such as plate tectonics, folding, volcanism, and erosion. Weathering and erosion by forces such as water, wind, and plant growth gradually break rocks into sediment and transport material from one place to another over long periods of time, shaping the surface of the planet. Human activities and settlement patterns are also influenced by landforms and geological characteristics of different regions.
Chapter 17 7th es
This document discusses air masses and weather systems. It defines air masses as large bodies of air classified by temperature and moisture content. As air masses move away from their source regions, their temperature and humidity change. The document describes the four main types of air masses - maritime tropical, maritime polar, continental polar, and continental tropical - and the weather typically associated with each. It also discusses fronts, where different air masses meet; cyclones and anticyclones; thunderstorms and tornadoes; hurricanes; and lake-effect snow. Meteorologists use tools like weather balloons, satellites, and computer models to analyze weather data and improve forecasting.
Earthquakes
The document provides information about earthquakes and volcanoes. It begins by defining an earthquake and volcano, and describes the formation of earthquakes. It then discusses plate tectonics and the different types of faults, earthquakes, and volcanoes. Examples are given of notable historical earthquakes and volcanic eruptions around the world, including in Chile, Alaska, Japan, Mount St. Helens, and Iceland. Earthquakes that have impacted Pakistan are also summarized.
Global Hazards
Global hazards can be classified into different types: hydro-meteorological hazards result from weather systems, geophysical hazards from tectonic processes, and context hazards affect the entire planet. Global warming is a context hazard that could increase the frequency and severity of other hazards like floods and droughts by altering global climate patterns. Vulnerability to hazards depends on factors like poverty, infrastructure, and emergency preparedness - developing nations tend to be more vulnerable due to lower response capacity. Reducing vulnerability and increasing coping ability are important for reducing overall disaster risk.
cyclone
Cyclones are rapidly rotating storm systems that form over warm tropical oceans. They are known as hurricanes in the Atlantic/Northeast Pacific, typhoons in the Northwest Pacific, and tropical cyclones in the South Pacific/Indian Ocean. Cyclones form through the rising of warm, moist air which causes an area of low pressure and draws in surrounding higher pressure air, fueling the storm system through heat release. They can cause extensive damage upon making landfall through strong winds, storm surge, heavy rain, and tornadoes.
Earthquake
Earthquakes are caused by a sudden release of energy in the Earth's crust that creates seismic waves. The largest recorded earthquakes include a 9.5 magnitude quake in Chile in 1960 and a 9.0 magnitude quake in Japan in 2011. Earthquakes can cause significant damage through ground shaking, fault ruptures, landslides, fires, liquefaction, tsunamis, and floods. Proper construction and seismic building codes can help reduce damage from earthquakes.
Natural disasters
- Natural disasters are events caused by natural hazards like floods, hurricanes, earthquakes, volcanic eruptions, and heat waves. They can cause financial losses, environmental damage, and loss of human life depending on a population's resilience and ability to prevent hazards.
- Common natural disasters include avalanches caused by accumulated snow and ice, earthquakes from seismic activity in the Earth's crust, volcanic eruptions from gas release or thermal contraction in volcanoes, and floods from overflowing bodies of water. Other disasters are droughts, tornadoes, heat waves, blizzards, and potential asteroid or comet impacts.

The interactive webinar included a review of the 2013 North-Atlantic hurricane season and concluded with a seasonal outlook for the 2014 North-Atlantic hurricane season.
Robichaud received his B.Sc. in meteorology from Lyndon State College, Vermont in 1995. After a few years as a weather forecaster in the private sector, he joined Environment Canada in 1998 as an aviation forecaster in Gander NL where he eventually became aviation weather program manager for Atlantic Canada. In 2003, Robichaud managed the National Aviation Weather Services contract with NAV CANADA and he has
also written a book on aviation weather for eastern Canada.
Robichaud moved to Halifax in 2004 to fill the new warning preparedness meteorologist role in Atlantic Canada where his primary focus is working closely with emergency management officials on a variety of different weather related issues including training,
exercising and support during actual weather events.
Hurricanes ppt
A presentation on hurricanes covering how hurricanes are formed,worst 10 hurricanes in history,damages and effects of hurricanes and Hurricane safety Tips.
A presentation on earthquake
This document provides information about earthquakes. It discusses that earthquakes are caused by the sudden release of energy stored in the Earth's crust along fault lines. Major earthquakes usually occur along belts that coincide with tectonic plate boundaries, particularly the Circum-Pacific Belt. Earthquakes can also be caused by human activities like reservoir construction. The effects of earthquakes include ground shaking, rupture, landslides, tsunamis, liquefaction, and fires. The document outlines safety rules both before, during, and after an earthquake to minimize injury.
mountainsearthquakesandvolcanoes-120925073803-phpapp01.pdf
This document provides information about plate tectonics and various geological features that result from plate movements, including mountains, earthquakes, and volcanoes. It discusses the three types of plate boundaries (divergent, convergent, transform) and describes how different stress types at boundaries can cause folding or faulting in the crust. Various mountain formation processes are also outlined, such as continent-continent collision, volcanic eruption, and subduction zones. The document also explains seismic wave types, how earthquakes and tsunamis occur, and provides details about volcano anatomy, eruption types, and global distribution of volcanoes.
Thunderstorms
This document discusses thunderstorms and tornadoes. It begins by defining a thunderstorm and outlining its typical characteristics. It then describes the three stages of thunderstorm development: the cumulus stage marked by updrafts, the mature stage with both updrafts and downdrafts, and the dissipating stage dominated by downdrafts. The document contrasts air mass thunderstorms and more severe storms, noting that some storms can be sustained for hours by wind shear and overshooting updrafts. Thunderstorm frequency is highest in Florida, the Gulf Coast, and parts of the Rockies and Plains.
naturaldisasters.pdf
This document provides an overview of various natural disasters including cyclones, earthquakes, tornados, volcanic eruptions, tsunamis, floods, wildfires, droughts, avalanches, and landslides. It describes each type of disaster and provides one or two illustrative examples, such as the deadliest tornado occurring in Bangladesh in 1989 or the largest flood being the Yellow River flood in China in 1887. The document aims to educate about different natural disasters and their impacts.
Chapter03 for CD.ppt
This document provides an overview of landforms and the geological and environmental processes that shape the Earth's surface over time. It discusses endogenous forces like plate tectonics, volcanism, and earthquakes that originate within the Earth, as well as exogenous forces like weathering, erosion, deposition, and mass wasting from external agents such as water, wind, and ice. These forces create landforms through gradual geomorphic changes spanning vast periods of geological time. The document also examines how human activities can accelerate natural surface processes through deforestation, agriculture, and construction.
NATURAL DISASTERS
The document discusses several natural disasters including earthquakes, hurricanes, landslides, tornados, tsunamis, drought, volcanoes. It provides key details about the causes and characteristics of each type of disaster such as earthquakes being caused by shifting tectonic plates, hurricanes forming over warm ocean waters and rotating counterclockwise in the northern hemisphere, landslides occurring on steep slopes due to factors like rain or earthquakes, and volcanoes erupting when underground pressure becomes too great.

- 1. Natural Disasters • Avalanche • Earthquake • Hurricane • Landslide • Tornado • Tsunami • Volcano Michael Ottinger
- 2. Avalanche • Large amount of snow travels down slope • Two components- snow filled slope and trigger • Powerful enough to snap trees and destroy buildings • When over, snow sets up very compact making rescue difficult • Caused more deaths in U.S. than earthquakes
- 3. Earthquake • Two plates shift/slide past each other • Plates touch at points called faults • Focus- point at which an earthquake begins • Epicenter- point right above focus where earthquake causes most movement • Millions occur worldwide • Can damage buildings and roads
- 4. Hurricane • Tropical cyclone with winds of 74 mph or greater • Takes days/weeks to gather strength to be considered hurricane • Process starts in warm, moist conditions over water • Coriolis force- causes wind to spiral counter-clockwise in Northern Hemisphere • Categorized on a 1-5 scale • Eye- circular area found at center of hurricane
- 5. Landslide • Earth moving down a slope • Abrupt- move fast/hard to detect • harmful to people • Gradual- move slow/mm or cm a year • damage property • Triggered by earthquakes or erosion
- 6. Tornado • Formed when cold air meets warm air • Take the shape of a funnel • Usually less than a mile wide • Form over land • Classified as • Weak- speed less than 110 mph, lasts 1-10 min • Strong- speed between 110- 205 mph, lasts 20 min • Violent- speed greater than 200 mph, lasts 1 hour
- 7. Tsunami • Large waves caused by earthquakes or volcanoes under water • As waves travel toward land they gather height • Speed- determined by depth of ocean • Pick up speed in deep water • Slow down as water shallows
- 8. Volcano • Vent connecting molten rock to Earth • Cone like shape • When pressure rises from water and CO2 in magma, volcano erupts • Active volcano- lava, gas, rock erupt
