This colorful and detailed PowerPoint and bundle explains the cause of earthquakes, the difference between magnitude (Richter Scale) and intensity (Mercalli Scale), how to triangulate an earthquake and the hazards associated with earthquakes. Body Waves S wave (transverse wave) The second type of body wave is the S wave or secondary wave, which is the second wave you feel in an earthquake. • Areas of surface or underground fracturing that can experience earthquakes are known as FAULT ZONES. “A Fault is a break or fracture b/w two blocks of rocks in response to stress.” This movement may occur rapidly, in the form of an earthquake or may occur slowly, in the form of creep. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. Earthquake can also cause floods and landslides. The tectonic movement of large plates on the Earth’s crust is what causes earthquakes to occur. Earth’s major earthquakes occur mainly in belts coinciding with the margins of tectonic plates. Tectonic earthquakes: The most common form of earthquakes, is caused by the movement of loose fragmented pieces of land on earth’s crust knowns as tectonic plates. Earthquake Magnitude Earthquake Severity Richter Magnitude Earthquake Effects Less than 3.5 Generally not felt, but recorded. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the … If you continue browsing the site, you agree to the use of cookies on this website. Tectonic earthquakes causes more damage than non-tectonic ones. Earthquakes are caused by sudden tectonic movements in the Earth’s crust. While an earthquake occurs only for a few seconds, the aftershocks can go on for days after that. See our Privacy Policy and User Agreement for details. Scientists use seismographs to record earthquakes. Landslides, triggered by earthquake, often cause more destruction than the earthquake themselves. Earthquake is a tragedy to life and property.

This causes building to sink and may cause landslides. Now customize the name of a clipboard to store your clips. This type of movement causes the formation of mountain ranges, volcanos, and earthquakes. The collision or the slipping of the tectonic plates causes vibrations in the earth due to rapid release of energy. Earth scientists use the angle of the fault with respect to the surface (known as the dip) and the direction of slip along the fault to classify faults. The energy can be released by elastic strain, gravity, chemical reactions, or even the motion of massive bodies. 5.4 - 6.1 At most slight damage to well-designed buildings.

EARTHQUAKE: A Tragedy to life and property • It is caused by the sudden release of slowly accumulating strain energy along a fault with in the earth’s crust. Earthquake in many cases can cause great loss of life. What causes an earthquake? 3.5-5.4 Often felt, but rarely causes damage. Dams: The build-up of pressure due to the storage of a large amount of water in the reservoirs behind large dams is considered to be a potential cause of earthquakes. 1. 1. • Causes of earthquakes • Effects of earthquakes 2. An earthquake is the shaking and vibration of the Earth's crust due to movement of the Earth's plates (plate tectonics). What causes an earthquake? Usually we only feel the bump and rattle of these waves. All dates are listed according to UTC time. Earth was hot when it formed, and has been cooling ever since (near the surface, for each km into Earth, the temperature rises by about 30deg. This is a list of earthquakes in 2020.Only earthquakes of magnitude 6 or above are included, unless they result in damage and/or casualties, or are notable for other reasons. If you continue browsing the site, you agree to the use of cookies on this website. Here its possible causes , effects and hazards they cause are discussed. Sometimes animals can hear the P waves of an earthquake. Earthquakes are caused due to sudden lateral or vertical movements in the crust of the Earth. 1. 2. Physical Causes The earthquake of Kobe at 546am on the 17th January 1995 was caused by the simple matter of the Philippine Plate being forced under the thicker and lighter continental plate the Eurasian. The most common type of earthquake is caused when two different tectonic plates collide with one rolling over the other, driving it down into the mantle. 3. Title: Prediction Of Earthquakes 1 Prediction Of Earthquakes A Geomatic Approach. Earthquake Origin Causes and effects Lab goals In an earthquake, will all parts of a city suffer the same damage? Where the crust is being compressed, reverse faulting occurs, in which the hanging-wall block moves up and over the footwall block – reverse slip on a gently inclined plane is referred to as thrust faulting.

Presentation Summary : The similarity between these 2 earthquakes lies in the fact that it is plate movement that generated the friction that caused the earthquake. Where the crust is being pulled apart, normal faulting occurs, in which the overlying (hanging-wall) block moves down with respect to the lower (foot wall) block. The windows rattle because the sound waves were pushing and pulling on the window glass much like P waves push and pull on rock. Now customize the name of a clipboard to store your clips. Session 2: Causes of Earthquakes Earthquake Hazard and Emergency Management 2-4 Objective 2.1 Describe the basic structure of the earth’s interior. Tectonic activity • Stresses are caused by convection currents in the asthenosphere • Diverging convection currents in the asthenosphere caused by tensional forces in rifts (normal faults) • Converging convection currents in the asthenosphere – Sima to Sima (Oceanic to Oceanic plates) • Creating 9.0 earthquakes on the Richter scale • Convection currents in the asthenosphere – Sial to Sial … If you continue browsing the site, you agree to the use of cookies on this website.
