Earthquakes
An earthquake is caused by the release of built-up pressure within the Earth's crust along fault lines. The focus is where the pressure is released within the crust, and the epicenter is the point on the surface directly above the focus. Earthquakes are measured on the Richter scale using seismometers, which detect the different types of waves that propagate during an earthquake: P-waves, S-waves, and surface waves. The effects of earthquakes can be primary, occurring directly from ground shaking, or secondary, resulting from primary effects like tsunamis or fires.
3.4.1 Earthquake Hazards
The document discusses tectonic plate processes and earthquakes. It describes how earthquakes occur at plate boundaries due to stresses from plate movements. Earthquakes at divergent boundaries pose little risk while those at convergent boundaries can be very hazardous, as seen in the 1985 Mexico City earthquake that killed over 10,000 people. The document also discusses earthquake measurement scales, the different types of seismic waves, and secondary hazards like tsunamis, landslides and liquefaction that can amplify earthquake damage.
geologic hazards.pptx
This document summarizes different types of geologic hazards including earthquakes, volcanic eruptions, and landslides. It describes earthquakes as the shaking or trembling of the ground caused by displacement below the surface. Major earthquake hazards are ground shaking, ground rupture, tsunamis, liquefaction, landslides, and fires caused by gas line ruptures. Volcanic eruptions occur when pressure builds up inside a volcano, causing ash, gas and magma to be released. Associated hazards are lava flows, lahars, pyroclastic falls, volcanic gases, and tephra falls. Landslides involve the downward movement of earth materials along slopes, often caused by earthquakes or heavy rain. Specific landslide
SCULPTURING THE EARTH SURFACE
This document summarizes key concepts related to geology and landscape formation. It discusses two major processes that change landscapes: endogenous processes that occur underground like plate tectonics, and exogenous processes above ground like weathering and erosion. Plate tectonics involves the movement of tectonic plates composed of continental and oceanic crust. Stresses from plate interactions cause deformation through tension, compression, and shearing, resulting in faulting and folding of the Earth's crust. Volcanism is another underground process where magma is forced to the surface. Weathering breaks rocks into fragments through physical and chemical processes, while erosion transports weathered material, and deposition accumulates eroded sediments.
Terremotos
This document provides information about earthquakes, including their causes, effects, historical examples, and safety procedures. It discusses how earthquakes are the result of the sudden release of energy in the Earth's crust. Key points covered include how earthquakes are measured, where they occur depending on tectonic plate movement, the damage they can cause to infrastructure from ground shifting and liquefaction, and what to do during and after an earthquake strikes to remain safe.
Plate Tectonics: An Introduction
The document provides information about plate tectonics, including tectonic events, hazards, and disasters. It discusses different types of earthquake and volcanic hazards such as ground shaking, lava flows, pyroclastic flows, and tsunamis. It also covers factors that influence people's perceptions of natural hazards, including magnitude, frequency, duration, and speed of onset. Areas that experience frequent, high magnitude events over a large area are more alert to hazards, while rare, moderate events are more easily forgotten. Locations are more vulnerable if the population, infrastructure, and economy are exposed and sensitive to hazards. Where natural hazards coincide with high vulnerability, disasters are more likely to occur.

It also mentions the San Andreas Fault as an example of a slip fault where the rocks have moved horizontally, creating earthquakes.
What is an Earthquake.docx
An earthquake is caused by a sudden release of energy in the earth's crust that creates seismic waves. Earthquakes are primarily caused by the movement of tectonic plates deep underground. The location where the earthquake starts is called the hypocenter, and the point directly above on the surface is the epicenter. Earthquakes can cause significant damage through ground shaking, surface ruptures, landslides, liquefaction, tsunamis and fires. While earthquakes also lead to some benefits like forming natural springs and mineral resources, they typically have many negative effects such as damage to buildings and infrastructure, loss of lives, and economic impacts.

MODULE 1. EARTHQUAKES AND FAULTS..pptx
An earthquake occurs due to a sudden slip or movement along a fault line in the Earth's crust. This movement releases built-up energy in the form of seismic waves that travel outward from the hypocenter or focus of the earthquake. The intensity of shaking and damage is greater near the epicenter, which is the point on the surface directly above the focus. Earthquake magnitude measures the energy released while intensity scales describe the observed effects on people and structures. Large earthquakes can sometimes generate tsunamis when the sudden movement of underwater faults displace large volumes of water.
Earthquakes: Causes, measuring their Characteristics, and Analyzing their Eff...
Earthquakes are sudden, violent shakings of the ground resulting from volcanic activity or movements within the Earth's crust. They can lead to significant destruction and loss of life, making understanding their causes, effects, and mitigation strategies critical. The primary causes of earthquakes include tectonic plate movements, volcanic activity, and human activities. Tectonic plates float on the semi-fluid asthenosphere, and their interactions at divergent, convergent, and transform boundaries lead to most earthquakes. Volcanic activity, involving the movement of magma within the Earth, can also trigger earthquakes, particularly in volcanic regions. Human activities, such as mining, the filling of large reservoirs, and hydraulic fracturing (fracking), can induce seismicity as well.
To measure earthquakes, seismographs detect and record ground motion, producing seismograms that help determine an earthquake's location and magnitude. The Richter Scale, though historically significant, is now less commonly used, with the Moment Magnitude Scale (Mw) being the standard for measuring the total energy released by an earthquake. The Modified Mercalli Intensity (MMI) Scale describes the effects of an earthquake in terms of human perception and structural damage. Earthquakes cause primary effects like ground shaking and surface rupture, which can lead to the collapse of buildings and infrastructure. The shaking can cause landslides, tsunamis, large sea waves from underwater earthquakes, and liquefaction, where saturated soil temporarily loses strength and behaves like a liquid.
Mitigating earthquake hazards involves implementing stringent building codes to ensure structures can withstand seismic forces, developing early warning systems to provide advance notice of shaking, educating the public about earthquake preparedness, and enforcing zoning laws that restrict construction in high-risk areas. Historical earthquakes, such as the 1906 San Francisco earthquake, the 2010 Haiti earthquake, and the 2011 Tōhoku earthquake and tsunami, highlight the devastating potential of these natural events and the importance of preparedness and resilience.
Predicting earthquakes with precise accuracy remains beyond current technological capabilities, though probabilistic seismic hazard assessment (PSHA) estimates the likelihood of different levels of ground shaking over specified periods. The seismic gap theory identifies segments of faults that have not experienced recent earthquakes and may be due for significant events. Technology and research play crucial roles in advancing our understanding and preparedness for earthquakes. Seismic networks, GPS, and InSAR technologies measure ground deformation, while supercomputing and simulations provide models for earthquake scenarios.

Temple of Asclepius in Thrace. Excavation results
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).

- 1. EARTHQUAKE HAZARDS AND RISK REDUCTION METHODS
- 2. Earthquake - tremor - is the perceptible shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth’s crust that creates seismic waves
- 3. Effects of an earthquake can be classified as : Primary effects are permanent features an earthquake can bring out. Examples include fault scarps, surface ruptures, and offsets of natural or human-constructed objects. Secondary effects happen when ground movement results to other types of destruction. Examples include landslides, tsunami, liquefaction and fire.
- 5. 1. Landslides - frequently triggered by strong ground motions. - includes a wide range of ground movement, such as rock falls, deep failure of slopes, and shallow debris flows.
- 6. 2. Tsunami - Seismic sea waves, a series of waves caused by the displacement of a large volume of water. - generated by the displacement of water during earthquakes
- 7. 3. Ground shaking or ground motion - Earth shakes with the passage of earthquake waves, which radiate energy that has been “stored” in stressed rocks, and were released when a fault broke and the rocks slipped to relieve the pent – up stress. - The strength of ground shaking is measured in the velocity of ground motion, the acceleration of the ground motion, the frequency content of the shaking and how long the shaking (duration)
- 8. 4. Ground or surface Rupture - is the offset of the ground surface when fault rupture extends to the Earth’s surface.
- 9. 5. Ground –induced ground subsidence and lateral spreading - Subsidence is the lowering of the ground surface - Lateral spreading occurs where sloping ground starts to move downhill , causing cracks to open up.
- 10. 6. Liquefaction Liquefaction happens when a body of solid sediments starts to behave like liquid due to extremely intense shaking. It usually happens to sediments located near bodies of water. As a result, structures or buildings on top will either sink or tilt as the liquefied body of sediment can no longer support it due to changes in its properties.
- 11. 7. Fire It is associated with broken gas pipes and damaged electrical lines as a result of damages caused by ground shaking to buildings and other infrastructures.
