川滇地区地震时的月日赤纬及黄经差特征比较
|
摘要
在进行潮汐应力对发震断层作用研究的基础上 ,对云南、四川两区域受到潮汐应力触发作用的强震和中强震发震时的月日赤纬及黄经差进行了计算 ,得到了其分布图象。结果表明 :云南、四川两不同构造区域上受到潮汐触发作用地震时的月日赤纬和黄经差分布图象是不同的 ,受到潮汐应力触发作用的强震和中强震的地震频次随月日黄经差的分布特征有明显差别。这些图象初步揭示了这两个区域的地震最易受到潮汐触发的日、月位置
Based on the studies of the tidal stress actions on seismic faults,the lunar-solar declinations and ecliptic-longitude differences for strong and moderate-strong triggered by tidal stress are calculated.The distribution patterns of the lunar-solar location parameters are obtained.The results indicate that the distribution patterns for the two tectonic regions in Yunnan and Sichuan are different.The characteristics of ecliptic-longitude-difference patterns for strong and moderatestrong earthquakes triggered by tidal stress are not alike.The patterns reveal the lunar-solar locations for the earthquakes that are most liable to be triggered by tidal stress.
