Which scale that is used for measuring the intensity of an earthquake (not Richter!) quantifies its effects on humans, objects of nature, and man-made structures on a scale of I through XII with XII denoting total destruction?
Mercalli intensity scale Mercalli intensity scale The Mercalli intensity scale is a seismic intensity scale used for measuring the intensity of an earthquake. It measures the "effects" of an earthquake. It is distinct from the moment magnitude ("M") usually reported for an earthquake, which is a measure of the "energy" released (sometimes misreported as the Richter magnitude, "M"). The intensity of an earthquake is not entirely determined by its magnitude. It is not based on first physical principles, but is, instead, empirically based on observed effects. The Mercalli scale quantifies the effects of an earthquake on the Earth's surface, humans, objects of nature,
PHIVOLCS Earthquake Intensity Scale PHIVOLCS Earthquake Intensity Scale The PHIVOLCS Earthquake Intensity Scale (PEIS) is a seismic scale used and developed by the Philippine Institute of Volcanology and Seismology (PHILVOLCS) to measure the intensity of an earthquake. It was developed as a response to the 1990 Luzon earthquake. PHILVOLCS cites seismic scale specifically developed for the Philippine setting, the different geography of each country and other "geological considerations" led to the development of PEIS. The scale measures the effect of an earthquake on a given area based on its relative effect to people, structures and objects in the surroundings. The PEIS was adopted in
