中文摘要: 2011 年3 月11 日在日本东北部海域发生MW 9.0 级强烈地震,汶川地震断裂带科学钻探(WFSD) 项目设在陕西汉中地区的体应变仪记录到了完整的应变数据。通过采集数据的分析,探讨了日本MW 9.0 级特大地震发生时的同震变化以及地震前后固体潮异常变化过程,分析了地震孕育、发生过程中应变固体潮的趋势性异常及畸变等各种异常现象,并针对这些应变异常进行分析,以期成果能为中国未来地震趋势的预测研究有所帮助。
Abstract:The MW9.0 earthquake occurred in the northeastern Sea of Japan,on March 11,2011. The volume strain meter in Wenchuan earthquake Fault Scientific Drilling (WFSD) recorded a complete response waveform at Hanzhong Prefecture,Shaanxi Province.By analyzing acquired data, some issues are studied and discussed by authors that including co-seismic changes of the whole process of MW9.0 mega-earthquake in Japan,the abnormal strain changes of solid tide prior to that earthquake and after,and the emerging process of that earthquake.Per this paper,the strain anomalies of the MW9.0 earthquake in Japan are analyzed in order to contribute to better forecast earthquake trends in China the future.
