瓦屋山水电站水库诱发地震危险性研究

瓦屋山水电站位于川南台陷南端，南邻峨眉山断块，水库南缘的毛沟断裂最新活动时期为晚更新世，水库处于活动性大地构造环境中，该区属于名山－马边－昭通过地震北段，以弱震活动为主，伴有少量中强地震，目前正处于地震活动期，从分析库区地质构造，水文地质，工程地质，地震活动等条件，并使用水库综合影响系数法，贝叶斯概率预测法，断层强度分析法，判定库区存在着发生构造型水库诱发地震的可能性，诱发地震强度Ｍｓ≤５．５。划     

Tracing the Forecast of Earthquakes Based on the Seismicity Characteristics of the Chi-Chi Strong Earthquake Swarm Sequence

The data of earthquakes with M≥3.0 during the 7 years from September 21, 1993 to September 20, 2000 recorded by the Taiwan Central Weather Bureau (CWB) show that there were 6 types of clear characteristics of seismicity during the Chi-Chi strong earthquake swarm of September 21. These 6 types of characteristics are (1) foreshock types, (2) seismic gaps, (3) seismic bands, (4) clustering activity of foreshocks and signal shock, (5) quiescence before the main shock and (6) secondary aftershocks in the aftershock sequence. Using the procedures for analyzing the yearly strong earthquake tendency, further tracing based on the earthquake sequence characteristics, and taking the Chi-Chi earthquake sequence as an example, tracing analysis of the earthquake tendency was attempted using the shorter time range of monthly rather than in a yearly time scale. An attempt was made to establish the procedures for tracing analysis of shallow-focus earthquakes in the seismic belt of western Taiwan. It is hoped that this can provide an analystical method for approaching the short-imminent time scale of seismometry-based earthquake forecasting.
