内容記述 | An empirical formula for the seismic intensity (JMA scale) I0 near the epicenter of an earthquake of magnitude M and focal depth h has been determined using 1114 data on seismic intensity recorded in Japan. The formula has the form M=0.23I0+O.105I02+1.2 log h+1.3 for M=2~8, h=3~100km, and I0≧0. For larger earthquakes (M=5~8), this formula is almost equivalent to M=1.2I0+1.2log h-0.83. | |||||
