用能流密度法研究昆明地区的地震活动时空分布特征
|
摘要
利用能流密度法,计算昆明及其周边部分地区(23.6°N~27.0°N,101.5°E~104.5°E)地震释放的能量,得到该区域能流密度对数值的等值线图.分析图形获得各时间段地震能量释放情况,研究了能量释放的区域、强弱,周期及其变化趋势,获得研究区域地震活动时空分布特征.认为研究区域已经进入地震活动强烈时期.讨论能流密度图在潜在震源区的划分和地震预报中的参考意义.
By using energy flux density method,seismic energy release in Kunming and the surrounding region(23.6°N～27.0°N,101.5°E～104.5°E)was calculated,and the contour maps of energy flux density logarithm values were obtained.Then the situation of the seismic energy release in each period was obtained by analyzing the contour map.The spatial temporal distribution characters of seismic activity in Kunming and the surrounding region was obtained by studying the region of the energy release,and its strength cycle and the variable trend.The results showed that the seismic activity of that region becomes stronger.The reference value of energy flux density map in the division of potential source zone and earthquake prediction was discussed at last.
