Earthquake intensities are defined in macroseismic scales. Since the early twentieth century, they usually contain 12 intensity degrees with the prominent exception of the seven degree Japanese Meteorological Agency (JMA) scale (later upgraded to ten degrees). Earthquakes generate different intensities at different places, generally decreasing ...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. [1] Earthquake shaking generally occurs in all three directions.
