GRACE卫星观测到的日本9.0级大地震重力前兆信息

Using 102 GRACE monthly solutions,the gravity precursor caused by Ms9.0 strong earthquake occurred on 11 March,2011 near the east coast of Honshu,Japan,had calculated and co-seismic gravity changes by using fault models from USGS with upword technology,then analyzed and compared both the results with each other.
