The Variations of Geomagnetic before the Menyuan MS6.4 Earthquake
摘要
Abstract
A variety of geomagnetic anomaly was appeared in the geomagnetic stations around epicenter before Menyuan MS6.4 earthquake. For example, There are abnormalies in the Z component LURR (load/unload response ratio) 、the Z component daily variation ratio、the Z component 21 integral hour values spatial correlation and geomagnetic low-point time offset. Analyzing the geomagnetic anomalies before and after the earthquake is beneficial to accumulate experience and examples for prediction earthquake by geomagnetic method for the future.In this article, all geomagnetic anomalies observed before and after the earthquake are counted. During demonstrate the relationship between geomagnetic anomaly and the earthquake, spatial relation between geomagnetic stations and epicenter of the earthquake, time relation of anomalies and the earthquake was analyzed. Finally we summed up an example using geomagnetic analysis method in earthquake prediction.关键词
