The relation between the magnitude and duration of earthquake

Peak ground acceleration (PGA) is equal to the maximum ground acceleration that occurred during earthquake shaking at a location. PGA is equal to the amplitude of the largest absolute acceleration recorded on an accelerogram at a site during a particular earthquake. Earthquake shaking generally occurs in all … See more Earthquake energy is dispersed in waves from the hypocentre, causing ground movement omnidirectionally but typically modelled horizontally (in two directions) and vertically. PGA records the acceleration (rate … See more Peak ground acceleration provides a measurement of instrumental intensity, that is, ground shaking recorded by seismic instruments. Other intensity scales measure felt intensity, based on eyewitness reports, felt shaking, and observed damage. … See more • Murphy, J.R.; o'brien (1977).

WebEarthquake magnitude is a measure of the “size,” or amplitude, of the seismic waves generated by an earthquake source and recorded by seismographs. (The types and nature of these waves are described in the section Seismic waves.) http://seismology.gl.ntu.edu.tw/papers/012_2003_Wu_et_al_BSSA_Intensity.PDF

WebMagnitude of acceleration = Rate of change of in the magnitude of velocity + Rate of changing the direction of motion The rate of change of in the magnitude of velocity is known as linear acceleration (let it be a l i n e a r ), and the rate of changing the direction of motion is known as centripetal acceleration (let it be a c u r v e ).
