累积危险度的动态演化及其与强震的关系

Abstract

Abstract: In this paper, at racing prediction method of risk sites of strong earthquakes by using the accumulation risk dimension has been improv ed and the ev olution of theaccumulation risk dimension in the Capital Circle and its neighbo ring areas since 1989 has been analyzed. The evolution process of the accumulatio nriskdimension reflects the course of earthquake preparation and tectonic stress sactivity. The value of the accumulation risk dimension increased before the two earthquakes whose magnitudes are grea ter than 6 and decreased after the earthquakes. The high value area of the accumulation risk dimension is the potential earthquake occurrence site.

Key words: Comprehensive earthquake prediction, Accumula tion risk dimension, Tracing Prediction, Capital circle and its neighboring areas.
