WebThe power of earthquakes is measured in two ways. Intensity, usually measured on the 12-point Mercalli scale, is a measure of the shaking observed at some particular location. Intensity varies from place to place. Magnitude is determined from seismic records and is measured on the Richter scale ( Richter, 1935 ).
