云南地区数字化地磁加卸载响应比异常特征分析
摘要
Abstract
The data of daily amplitude variation(ΔZ)of digital geomagnetic vertical component(Z)in Yunnan area are calculated with the method of geomagnetic loading-and-unloading response ratio.The anomaly changes before the 8 earthquake cases with MS≥5. 0 in Yunnan region from January 2009 to March 2013 are studied.The results show that the anomaly high value of response ratio has certain instruction significance to impending of earthquake withMS≥5 in the short term in Yunnan area,especially the impending of earthquakes withM≥5 .5 .关键词
