日本Ms9.0地震前的连续重力观测异常
GRAVITY ANOMALIES IN BEFORE Ms9.0 EARTHQUAKE IN JAPAN OBSERVED BY CONTINUOUS RELATIVE GRAVIMETER IN CHINA
摘要
Abstract
After Ms9.0 earthquake in Japan, the data of 17 gPhones and GS15 continuous relative gravimeters 3 days before the huge earthquake were analyzed. It is shown that there were some unknown gravity anomalies of gPhone and GS15 in Wushi, Zhengzhou and Chengdu station. The preliminay analysis shows that the records at Chengdu and Wushi stations had the type of spindle gravity disturbance 16 hours before the Ms7. 3 earthquake of Japan in 2011-03-09. And the gravimeter' s records in Zhengzhou station had the cylindrical gravity disturbance not only before the Ms7.3 earquake but also the Ms9.0 earquake in Japan. Although the tropical cyclones, the impact of human disturbance and other factor can be ruled out, the relationship between the gravity disturbance and the earthquake in Japan and the data of even more time scale are remained to be further analyzed.关键词
