华南地区基于小波变换的地震活动性分析
The Characteristics of Seismic Activity in South China by Using Wavelet Transform
摘要
Abstract
With the benioff strain curve data of the southeast coastal seismic belt and middle reaches of Yangtze River seismic zone since 1 500,the paper achieves the seismic active and quiet periods in different time scales by using multi-scale wavelet transform method.The results show that the active period of earthquake with M ≥ 5 in southeast coastal seismic belt in 10 years scale is about 300 years,the active period of earthquake with ML≥4 (since 1970) is about 5 years,and now this area is stepping into an ML≥4 active period.The middle reaches of Yangtze River seismic belt has an obvious " active-quiet period" feature,and currently in its fourth active period.Since 1970,earthquake with ML≥4 has 3 active periods and it may be still in ML≥4 active period in the next several years.关键词
