运用改进的地震定位交切法重定位2001—2010年云南地震
Relocation of earthquakes in Yunnan Province from 2001 to 2010 employing a modified intersection method
摘要
Abstract
The intersection method is one of the traditional methods of earthquake location. However, the traditional method is deifcient in location accuracy especially for hypocenter depth, because it is based on homogeneous or laterally homogeneous model. Thus, the key to improve the traditional intersection method is using the 3-D speed model that is more accord with practical model. So, we have modiifed it in the suitability for 3-D complex velocity models. The hypocenter is located at the point that the focal loci most intersect. We apply this method to Yunnan region, and get a high precision result.关键词
