Seismic intensity scales categorize the intensity or severity of ground shaking (quaking) at a given location, such as resulting from an earthquake. They are distinguished from seismic magnitude scales, which measure the magnitude or overall strength of an earthquake, which may, or perhaps may not, cause perceptible shaking. Intensity scales are based on the observed effects of the shaking, such as the degree to which p… WebApr 13, 2024 · In the Philippines, the intensity of an earthquake is determined using the PHIVOLCS Earthquake Intensity Scale (PEIS). Types of earthquake There are two types of earthquakes: tectonic and volcanic earthquakes. Tectonic earthquakes are produced by sudden movement along faults and plate boundaries.

WebJul 27, 2024 · The intensity map provides predicted intensities for areas without reported intensities. The 27 July 2024 M7.0 earthquake was felt with a maximum ground shaking intensity of PEIS VII (Destructive) with some isolated areas experiencing PEIS VIII. At PEIS VII, most people get frightened and run outdoors. science in fancy writing
