GRACE卫星观测到的日本9.0级大地震重力前兆信息
GRAVITY CAUSED BY Ms9.0 STRONG EATHQUAKE IN JAPAN PRECURSOR DETECTED BY GRACE
【摘要】 利用102个GRACE卫星月重力场模型,提取了2011年3月11日日本9.0级大地震的重力前兆信息,同时利用USGS发布的断层模型结合向上延拓技术计算了理论同震重力变化,并对结果进行了比较和分析。
【Abstract】 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.
