| 中文摘要 | 通过计算云南163个地震震源处沿地震主应力方向的潮汐应力分量,分析了地震的潮汐应力触发力学机制.结果表明,所研究的地震中有62%受到了潮汐应力的触发作用.在此基础上,对受到潮汐应力触发的地震发震时的天体位置特征进行了研究,得到了具有潮汐应力触发物理基础的地震时的月日黄经差、月日赤纬和月日天顶距的分布图像.图像显示,云南地区的地震在新月期间和上下弦附近较易受到潮汐应力的触发;受到潮汐应力触发作用的地震发震时刻的月日赤纬有明显的密集分布条带特征,地震频次在月、日天顶距分别为30°～140°和20°～140°范围内为平均优势分布区间. |
| 英文摘要 | By calculating additional tidal stress components along seismic principle stress at focuses of 163 earthquakes in Yunnan, the mechanism of tidal stress triggering earthquakes is analyzed. The result indicates that 62 % of studied earthquakes are triggered by tidal stress. Based on this, the characteristics of related celestial body positions at the occurrence time of the triggered earthquakes are studied. The distribution patterns, which have tidal-triggering physical basis, of lunar-solar ecliptic longitude differences and declinations and zenith distances are obtained. The patterns show that earthquakes in Yunnan are apt to be triggered by tidal stress during new moon and the first or third quarter of moon. The lunar-solar declinations at the occurrence time of the triggered earthquakes have banded dense distribution. The average superior domains of triggered-earthquake frequency distribution against lunar-solar zenith distances are 30 degrees similar to 140 degrees and 20 degrees similar to 140 degrees, respectively. |
