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 has ten intensity scales represented in Roman numerals with Intensity I being the weakest and Intensity X being the strongest.
