deadliest earthquake in history killed 840‚000 people‚ But many other earthquake have caused the dead of more than 100‚000 people and isn’t unusual‚ even in modern times‚ for an earthquake death toll to reach 20‚000 to 20‚000 people with hundreds of thousands left homeless. There are four factors that affect the casualty rate and economic impact of earthquake: magnitude‚ location‚ quality of construction of building‚ and timing. Magnitude The magnitude‚ or strength‚ of an earthquake is measured

2010 Haiti Earthquake - Case Study Location A 7.0 magnitude earthquake strikes Haiti on Tuesday‚ 12th of January 2010 at 16.53 local time (21.53 GMT). The earthquake occurred in Port-au-Prince‚ the capital city of Haiti. The focus of the earthquake was 13 km below the surface of the earth. Causes The earthquake was caused by the North American Plate sliding past the Caribbean Plate at a conservative plate margin. Both plates moved in the same direction‚ but on plate moves

With no immediate precursors‚ a magnitude 5.1 earthquake occurred and was accompanied by a rapid series of events. Mount St. Helens produces small to large explosive eruptions‚ which send varying quantities of ash and tephra into the atmosphere Tephra (rock fragments and particles ejected by a volcanic eruption

name 4/23/12 Earth Science Earthquake essay Earthquakes are a very dangerous natural disaster‚ if strong enough; they could destroy the best-built buildings. They are caused by a sudden shift in the tectonic plates. Earthquakes can also cause other types of disasters too. They could cause tsunamis or volcanic eruptions. However earthquakes erupt unpredictable and can kill many people unpredictable. Seismometers can detect the strength of the earthquake‚ which then gives a number on the Richter

Earthquake Prediction Earthquakes are one of the most destructive forces known to mankind. An earthquake can have enough power to destroy an entire city and has the potential to be felt 1000 miles away. An earthquake is a series of vibrations induced in the earth’s crust by the abrupt rupture and rebound of the rocks in which elastic strain has been slowly accumulating. Earthquakes happen along vault lines like the San Andres Fault. A fault plane is the surface of a fault fracture along which the

The short answer is that earthquakes are caused by faulting‚ a sudden lateral or vertical movement of rock along a rupture (break) surface. Here’s the longer answer: The surface of the Earth is in continuous slow motion. This is plate tectonics--the motion of immense rigid plates at the surface of the Earth in response to flow of rock within the Earth. The plates cover the entire surface of the globe. Since they are all moving they rub against each other in some places (like the San Andreas

which approach the country. Earthquake An earthquake (also known as a quake‚ tremor or temblor) is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. The seismicity‚ seismism or seismic activity of an area refers to the frequency‚ type and size of earthquakes experienced over a period of time. Earthquakes are measured using observations from seismometers. The moment magnitude is the most common scale on which earthquakes larger than approximately 5
