Define earthquake intensity.

Earthquakes are recorded by a seismographic network. Each seismic station in the network measures the movement of the ground at that site. The slip of one block of rock over another in an earthquake releases energy that makes the ground vibrate.

Jan 1, 2016 · The size and damaging effects or severity of an earthquake are described by measurements of both magnitude and intensity. In seismology (the study of earthquakes), scales of seismic intensity are used to measure or categorize the effects of the earthquake at different sites around its epicenter. Various seismic scales can be used to measure and ... Prior to the development of the magnitude scale, the only measure of an earthquake's strength or "size" was a subjective assessment of the intensity of shaking observed near the epicenter of the earthquake, categorized by various seismic intensity scales such as the Rossi-Forel scale.

An earthquake is caused by a sudden slip on a fault. The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.Earthquake vulnerability can be assessed and predicted through scientific analysis of earthquake risk map, and thus damages can be decreased through ...
