What Is Earthquake Nasa What Is An Earthquake Wikipedia

The location where an earthquake begins is called the epicenter.

What is earthquake all about what is an earthquake how does it occur. An earthquake warning system or earthquake early warning system is a system of accelerometers seismometers communication computers and alarms that is devised for notifying adjoining regions of a substantial earthquake while it is in progress. Earthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to toss people around and destroy whole cities. Earthquakes are usually quite brief but there may be many over a short time frame.

An earthquakes most intense shaking is often felt near the epicenter. An earthquake is the shaking of the surface of the earth resulting from the sudden release of energy in the earths lithosphere that creates seismic waves. This is a list of major earthquakes by the dollar value of property public and private losses directly attributable to the earthquake.

An earthquake also known as a quake tremor or temblor is the shaking of the surface of the earth resulting from a sudden release of energy in the earths lithosphere that creates seismic wavesearthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to propel objects and people into the air and wreak destruction across entire cities. Rank values are assigned based on inflation adjusted comparison of property damage in us dollars. This is not the same as earthquake prediction which is currently incapable of producing decisive event warnings.

Slow earthquake a discontinuous earthquake like event that releases energy over a period of hours to months rather than the seconds to minutes characteristic of a typical earthquake. An earthquake also known as a quake tremor or temblor is the shaking of the surface of the earth resulting from a sudden release of energy in the earths lithosphere that creates seismic wavesearthquakes can range in size from those that are so weak that they cannot be felt to those violent enough to propel objects and people into the air and wreak destruction across entire cities. Wherever possible indirect and socioeconomic losses are excluded.

About 50 earthquakes occur each day around the world. Their report which was released in april outlines a 20 year plan to deploy a network of satellites the global earthquake satellite system gess using insar to monitor fault zones around the world. The study of earthquakes is called seismology.

A group of nasa and university scientists led by carol raymond of jpl recently studied the feasibility of forecasting earthquakes from space. An earthquake is the sudden movement of the earths tectonic plates resulting in shaking of the groundthis shaking can result in the damage of various structures such as buildings and further breakdown of the earths surface. Submarine earthquake an earthquake that occurs underwater at the bottom of a body of water especially an ocean.

Supershear earthquake an earthquake in which the propagation of the rupture along the fault. Although most of these do not have a noticeable effect on life and work large magnitude earthquakes occurring near cities and towns can cause catastrophic devastation through destruction of buildings and infrastructure.
