Accelerations near faults that have moved during moderate-sized earthquakes
David M. Boore, Robert A. Page
1972, Open-File Report 72-43
Peak ground accelerations recently recorded within 10-15 km of faulting during moderate-sized earthquakes (m = 4 to 6) are significantly underestimated by many, if not most, of the empirical acceleration-distance relations commonly used in seismic engineering. The recent data show a rapid decrease of peak acceleration with increasing distances (at...
