The idea of a logarithmic earthquake magnitude scale was first developed by Charles Richter in the 1930's for measuring the size of earthquakes occurring in southern California using relatively high-frequency data from nearby seismograph stations. clancy obit duxbury

"WebThe Mercalli Scale . The Mercalli scale quantifies the power of an earthquake by evaluating its impact on the Earth’s surface. Given human responses and human-made structures, the Mercalli scale rates earthquakes on a scale of 1 to 12, with 1 meaning that nothing was observed and 12 signifying absolute pulverization.
