About this document
PHIVOLCS Earthquake Intensity Scale by John Forte is a document available to read on EtoBox.
The PHIVOLCS Earthquake Intensity Scale (PEIS) is a 10-point scale used to describe the intensity or severity of ground shaking from an earthquake. It ranges from I (scarcely perceptible shaking) to X (completely devastating shaking that destroys practically all man-made structures). The scale provides descriptions of typical shaking effects at each intensity level, such as the swaying of hanging objects, cracking of plaster, toppling of chimneys, and massive landslides.
