WebThe new seismic hazard maps are given for three ground motion measures: peak ground acceleration (PGA) and spectral acceleration (SA) at 0.2 s (5 Hz) and 1.0 s (1.0 Hz) … 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 • Earthquake simulation • Japan Meteorological Agency seismic intensity scale • Spectral acceleration See more Study of geographic areas combined with an assessment of historical earthquakes allows geologists to determine seismic risk and to create seismic hazard maps, which show the likely PGA … See more Peak ground acceleration provides a measurement of instrumental intensity, that is, ground shaking recorded by seismic instruments. … See more • Murphy, J.R.; o'brien (1977).
