Earthquake’s magnitude is determined by the use of seismograph, an instrument which continuously records, ground vibration. It is measured on the Richter scale. This scale was developed by Charles Francis Richter in 1935 ... Earthquake shaking is measured using the Modified Mercalli Intensity (MMI) Scale. Whereas the magnitude of an earthquake describes how much energy is released by an earthquake, calculated according to the length of a fault rupture and how far it slipped, the MMI scale describes the intensity of earthquake shaking at a specific location by considering its effects on people, objects and buildings. Moment magnitude, a quantitative measure of an earthquake’s magnitude (or relative size), developed in the 1970s by Hiroo Kanamori and Thomas C. Hanks.

Intensity is the measure of shaking at different locations around the earthquake. Intensity values vary from place to place, depending on the distance from the earthquake and the underlying rock or soil makeup. The intensity, or macroseismic intensity, represents a classification of the severity of ground-motion shaking during an earthquake on the basis of observed effects at a given place (Grünthal et al. 1998 ).

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter..
