TY - JOUR A2 - Chen, Yun-tai AU - Zhang, Xuemin AU - Shen, Xuhui PY - 2011 DA - 2011/08/07 TI - Electromagnetic Anomalies around The Wenchuan Earthquake and Their Relationship with Earthquake Preparation SP - 904132 VL - 2011 AB - Electromagnetic precursors before the Wenchuan earthquake on May 12, 2008 were collected and summarized on the basis of related published papers. The relationship between electromagnetic anomalies and different earthquake preparation stages was analyzed, and an entire seismic preparation process was constructed according to corresponding anomalies in different electromagnetic parameters. It is illustrated that stereo electromagnetic observation is useful in the understanding of earthquake preparation mechanism. It is inevitable that a lot of problems exist in anomaly distinguishing and coupling mechanism analysis, which needs further studies in future.
