查询词典 seismicity

Based on systematic analysis, nine seismometry parameters that response earthquakes well in North China are selected, which are seismic frequency, seismicity scale, mf-value, b-value, D-value,η-value, seismicity intensity entropy and seismicity time entropy. Using synthetic anomaly index method, we calculated their seismic anomaly index values separately and synthesized these values into a chronogenesis curve. After studying its short-term anomaly characteristics to earthquakes, the criterion index for M≥5.8 earthquakes in North China is obtained. The R-value test indicts that it has good prediction effect.

Seismicity trend before the earthquake was forecasted according to seismicity feature and commensurable characteristics of strong earthquake activities of Sichuan and Yunnan areas.Since Oct., 1995, a lot of kinds of the anomalies with large amplitude, such as radon and CO2 contents in groundwater and groundwater level etc.synchronized in a wide range of western Yunnan, especially along Zhongdian—Nanjian seismic area. The characteristics of these short-term anomalies are introduced and analysed.
