华安汰内井映震特征分析

对华安汰内井水氡、水电导率测值进行分析,得出各测项对中国台湾Ms≥7强震和福建内陆4级以上地震的映震特征,结果发现:①去除年动态规律后,水氡测值在中国台湾Ms≥7强震前多表现为高值异常,异常持续时间大多在半年以上,异常结束到发震时间间隔较短；②在2007-2008年发生的8次福建内陆4级地震前,水氡原始日值表现为短临或...

Analysis of the earthquake reflection in Hua'an Tainei well

Based on analyzing the observations of radon and conductivity in Tainei well in Huaan, the reflection characteristics of Ms≥7 strong earthquake in Taiwan, China, and M 4. 0 earth quake in Fujian Province inland are educed. ①The radon＇s value shown high value anomaly after wiping off year law before Ms≥7 strong earthquake in Taiwan, China, and it lasts more than six months, the time interval between the end of anomaly and the happens of earthquake is short; ②The short-term abnormities of the raw data of radon occurred before 8 times earthquakes in Fujian Province inland during 2007 2008. especially those distributed along the Yong＇ an-Jinjiang fault zone and its nearby areas showed good reproducibility; ③Before the parts of strong earthquake in Taiwan and M 4.0 earthquake in Fujian Province inland, the conductivity of water showed high value for 1-2 months with amplitude three times more than deviation.
