摘要
Abstract
We studied the seismicity before and after the MS=7.8 Tangshan event on July 28, 1976 (39(28(N, 118(11(E) and the results show that in 3 regions outside of the source zone, seismicity rate increasing were observed, which was significant in 0.99 significance level using Z-statistic test and was proposed to be triggered by the MS=7.8 Tangshan earthquake. The magnitude of the greatest triggered event was 5.5. The epicenter distances of these earthquakes were several ten kilometers to 300 km. The static stress change (CFS of Coulomb failure was calculated using an elastic dislocation model in half space and the (CFS on the major rupture directions in these three regions were positive.关键词
