2011年3月11日日本发生了MW 9.0级地震，在这次地震中，上海地区的两个形变台站的7套观测仪器都记录到了不同程度的异常现象，应变及地倾斜出现幅度不同的震荡波，佘山台垂直摆东西分量在初动时就记录到最大波动，而佘山重力仪记录到的最大波值出现在震级更小的余震发生后。此外查山台钻孔倾斜北南分量以及佘山台垂直摆东西分量均在震后一段时间出现了与GPS记录相一致的加速倾斜。通过将上述现象进行简述分析，以期进一步深入了解上海地区的地形变响应特征。

During the course of Mw 9.0 earthquake occurred in Japan on March 11, 2011, the anomalous phenomenon recorded by the apparatus of strain and ground deformation in some region of Shanghai. By analyzing acquired data, some issues are studied and discussed by authors that indude co-seismic changes of the whole process of Mw 9.0 mega-earthquake in Japan and the abnormal changes after that earthquake for the better understanding of the deformation characters in Shanghai region.
