日本Ms9.0地震前的重力高频扰动
PRE-SEISMIC GRAVITY DISTURBANCE OF HIGH FREQUENCY BEFORE Ms9.0 EARTHQUAKE IN JAPAN
摘要
Abstract
We have chosen fourteen gPhone spring gravimeters of China Gravity Network to form two observation sections, and analyzed the observation records( in March 1 to 10) before the Ms9.0 earthquake near Japan east coast. The results indicate that a kind of bell-like of abnormal gravity disturbance occurring at all littoral observation stations and the magnitude of abnormal gravity disturbance attenuate with the distance from epicenter.关键词
