| 摘 要： | 利用小波变换分析中国西部及邻区1700年以来M≥7级和M-T图分析1700年以来M≥7.8级地震活动,除了得到和其他学者研究基本一致的几个十年尺度周期结果外,还得到百年左右尺度的地震活动周期结果,再与太阳黑子活动进行比较,发现地震活动与太阳黑子数在百年左右尺度周期上具有负相关性,地震高活动时段对应太阳黑子低值时段.此外...

| Abstract: | This article used Morlet wavelet (M≥7) and M-T (M≥7.8) method to analyze the seismic activities of western China and its adjacent areas since 1700. The result shows that in this area exists hundred-year-scale cycle of seismic activity besides ten-year-scale cycles that other scholars have studied. Comparing with sunspot activity, we found that the seismic activity of western China and its adjacent areas has negative correlativity with sunspot activity at hundred-year-scale cycle, When the seismic activity strengthens, the sunspot activity weakens. In addition, western China and its adjacent areas now may be at activity period from the analysis of the article. |
