THE CHARACTERISTICS OF THE INDUCTANCE ANOMALY AT CHANGQING STATION BEFORE THE BOHAI SEA EARTHQUAKE |
| |
| Abstract: | In this paper,the characteristics of the inductance anomaly at Changqing station before theBohai Sea earthquake (7.4Ms) are analysed and summarized:(1).there is an abrupt rise beforethe earthquake to form a sawtooth-like curve;(2).the slope of the curve changes apparentlythree monthes before the earthquake;(3).the curve recovers to its normal form gradually afterthe earthquake. |
