日本9.0级地震甘肃地下流体资料同震响应特征分析
Characteristics of the Co-seismic Response of Fluid Data in the Gansu Area Prior to the 2011 Tohoku M9.0 Earthquake,Japan
摘要
Abstract
During the Tohoku M9.0 great earthquake of March 11th,2011,the digital observation data on underground fluids in the Gansu area showed different degrees of co-seismic response.In this study,we analyzed the co-seismic change characteristics and response ability of the digital water levels and water temperature in the Gansu area during the earthquake.It was found that the co-seismic response of the water level had two main patterns:oscillation and mutation.The water level of most wells returned to the initial state a short time after the earthquake.The recorded water temperature data showed a lower response capacity than the water level data.Only one of the measurement instruments recorded the co-seismic response of the water temperature,but this was j ust a short-term fluctuation and it easily recovered.关键词
