What is intensity of an earthquake.

This expected intensity value then describes the anticipated effects of the earthquake in terms of damage to buildings. Because intensity is defined by observed effects (specifically damage), an intensity attenuation equation is an expression of the expected damage distribution from any earthquake, as a function of magnitude and distance.An earthquake refers to the shaking of the earth’s surface caused by a sudden release of energy within the earth’s crust. This release of energy generates seismic waves, commonly known as S waves. The intensity and characteristics of an earthquake are determined by the seismic activities occurring in a specific region. The strength of a quake on the ground is expressed as "intensity." The intensity will vary, however, at the different levels of a building. It is therefore ...Monitoring Earthquakes. We monitor earthquakes by measuring the seismic waves they generate. Seismic waves are generated when the two sides of a fault rapidly slip past each other. Measuring these waves help us determine the type of earthquake, its origin, and its strength/intensity. Many faults do not break the surface in an earthquake, so ...

What is intensity? Intensity describes how strong the shaking is at a given location. In the United States and many other locations, intensity values are described with Roman numerals from I (barely perceptible) to X (widespread destruction), using the Modified Mercalli Intensity scale.

The intensity is a number (written as a Roman numeral) describing the severity of an earthquake in terms of its effects on the earth’s surface and on humans and their structures. Several scales exist, but the ones most commonly used in the United States are the Modified Mercalli scale and the Rossi-Forel scale. The two largest earthquakes in the recent series are relatively shallow, with the mainshock 18 kilometers, or 11 miles, deep and the 7.5 magnitude aftershock at 10 kilometers (just over 6 miles) deep. Because the quakes are relatively shallow, the intensity of the shaking is severe.
