Maximum intensities are indicated on the Modified Mercalli intensity scale and are sourced from United States Geological Survey (USGS) ShakeMap data. Earthquakes are caused by sudden tectonic movements in the Earth’s crust. An earthquake is caused by a sudden slip on a fault. Earthquake causes damage to the building, bridges, dams. 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. 4. This type of movement causes the formation of mountain ranges, volcanos, and earthquakes. 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. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the … These vibrations pass through the earth’s surface in waves and cause the earthquake. These are smaller earthquakes that happen in the same place before the larger earthquake follows. The energy can be released by elastic strain, gravity, chemical reactions, or even the motion of massive bodies. Here its possible causes , effects and hazards they cause are discussed. 4. While an earthquake occurs only for a few seconds, the aftershocks can go on for days after that. The collision or the slipping of the tectonic plates causes vibrations in the earth due to rapid release of energy. What causes an earthquake? Aftershocks ...

What causes an earthquake? 2. If you continue browsing the site, you agree to the use of cookies on this website. Earthquake can also cause floods and landslides. Vibrations (earthquakes) occur as the deformed rock “springs back” to its original shape (elastic rebound). Volcanic activity can cause earthquakes, as can human activities like nuclear explosions carried out underground. Clipping is a handy way to collect important slides you want to go back to later. Slippage at the weakest point (the focus) occurs. 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. ; Volcanic earthquake: The less prevalent compared to the tectonic variety, these earthquakes happen before or after the eruption of a volcano.It is caused when magma leaving the volcano is filled by rocks being pushed to the surface. Describe how the contents of such kits help people survive the first days after an earthquake or volcanic eruption. This has long been apparent from early catalogs of felt earthquakes and is even more readily discernible in modern seismicity maps, which show instrumentally determined epicentres. Effects of an Earthquake: 1. Learning Objectives What if you could explain where the earthquake and tsunami in Japan happened, what caused these events and describe some of the ways the north east coast of Japan has been affected.

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. Earthquake Origin Causes and effects Lab goals In an earthquake, will all parts of a city suffer the same damage? How Do The Earthquakes In New Zealand And Nepal Compare? 2 Section 2 Measuring Earthquakes Every day there are about 8,000 earthquakes. Earthquakes are caused by the sudden release of energy within some limited region of the rocks of the Earth. year … Earthquake is a tragedy to life and property. An earthquake also has foreshocks. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. The main cause is that when tectonic plates, one rides over the other, causing orogeny collide (mountain building), earthquakes. Msc 2nd Earthquakes are the vibrations of part of the earths crust. 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 … Buy with confidence! Usually we only feel the bump and rattle of these waves. The primary cause of an earthquake is faults on the crust of the earth. Sometimes animals can hear the P waves of an earthquake. Earthquake in many cases, can cause great loss of life. This causes building to sink and may cause landslides. Most too small to notice After an earthquake the two most ... – A free PowerPoint PPT presentation (displayed as a Flash slide show) on PowerShow.com - id: 571359-NzE4N 2.

What we are looking for is key detail to explain what happened, with locations and analysis of how the north east coast of Japan has been affected. Looks like you’ve clipped this slide to already. An earthquake is the shaking and vibration of the Earth's crust due to movement of the Earth's plates (plate tectonics). The largest fault surfaces on Earth … 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. The lecture will be enhanced if the instructor presents … Browse earthquakes ppt resources on Teachers Pay Teachers, a marketplace trusted by millions of teachers for original educational resources. This quake, 7.2 on the Richter Scale, was the worst in half and century. 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. Causes, Effects and Precautions against Earthquake, Earthquake causes and safety measurements, No public clipboards found for this slide. Earthquakes are caused when a break in the Earth's surfa The windows rattle because the sound waves were pushing and pulling on the window glass much like P waves push and pull on rock. The tectonic movement of large plates on the Earth’s crust is what causes earthquakes to occur. However, earthquakes cannot be detected and whenever they occur, they can cause massive damages to property and even kill people. 178695 PPT. 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.

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. Causes of Earthquakes 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 tectonic plates are always slowly moving, but they get stuck at their edges due to friction. Earthquake Magnitude Earthquake Severity Richter Magnitude Earthquake Effects Less than 3.5 Generally not felt, but recorded. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. The second biggest earthquake on record was the 2004 Indian Ocean earthquake which caused a devastating tsunami. Causes of earthquakes Types of earthquakes Genetic classification of earthquakes Types of earthquakes 1 1. 3.5-5.4 Often felt, but rarely causes damage. • Causes of earthquakes “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.
