Seismic intensity scales
SCALE USED TO MEASURE EARTHQUAKE INTENSITY
Seismic intensity scale; Seismic intensity
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.
