2010年青海及苏门答腊7级以上地震异常特征分析

摘要

运用山西侯马形变台2010年3-5月DSQ水管倾斜仪、SSY-Ⅱ洞体伸缩仪数字化的观测资料,对4月7日印度尼西亚苏门答腊7.8级、4月14日青海玉树7.1级、5月9日苏门答腊7.4级地震前的短临异常,做形态、差分、速度、同震响应分析,并对异常的变化特征做相应总结,为今后地震预报分析,提供参考.%With the digital observation data of the DSQ tiltmete and the SSY- II extensometer at the Houma station in Shanxi Province between March to May in 2010, the form, difference, velocity, co-seismicity of the short-term and imminent anomalies of the Sumatera M 7. 8 earthquake on April 4, the Yushu M 7.1 earthquake on April 14, and the other Sumatera M 7. 1 earthquake on May 9 are analyzed. The variant characteristics of anomalies are summarized for the reference in the earthquake prediction in the further.
