WebWhat is Peak Ground Acceleration. 1. Peak Ground Acceleration (PGA) is a measure of the acceleration of the ground during earthquake. This is the most important parameter for … 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 In India, areas with expected PGA values higher than 0.36 g are classed as "Zone 5", or "Very High Damage Risk Zone". See more • Murphy, J.R.; o'brien (1977). "The correlation of peak ground acceleration amplitude with seismic intensity and other physical parameters". Bulletin of the Seismological … See more Study of geographic areas combined with an assessment of historical earthquakes allows geologists to determine seismic risk and to create See more Peak ground acceleration provides a measurement of instrumental intensity, that is, ground shaking recorded by seismic instruments. … See more • Earthquake simulation • Japan Meteorological Agency seismic intensity scale See more
