Define earthquake intensity

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 size, as measured by the Richter Scale is a well known, but not well understood, concept. The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations.

Figure 1. The destructive effect of an earthquake is palpable evidence of the energy carried in these waves. The Richter scale rating of earthquakes is related to both their amplitude and the energy they carry. (credit: Petty Officer 2nd Class Candice Villarreal, U.S. Navy) All waves carry energy. The energy of some waves can be directly observed.Pagination. Although you may hear the terms “seismic zone” and “seismic hazard zone” used interchangeably, they really describe two slightly different things. A seismic zone is used to describe an area where earthquakes tend to focus; for example, the New Madrid Seismic Zone in the Central United States. A seismic hazard zone describes ...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. An earthquake’s strength can be measured in a variety of ways; the two most common methods are intensity and magnitude. Earthquake intensity is a measurement of the surface damage resulting from an earthquake. It is most commonly measured with the Mercalli scale as seen in Figure 10.Intensity; Definition: Magnitude is the measurement of the size of an earthquake: Intensity is the measurement of the strength of the earthquake: Measured by: To measure the magnitude of the earthquake, a seismograph is used: The intensity is measured by calculating the damage caused by the earthquake: Value
