| 摘 要： | 分析了延庆五里营井汶川M8.0地震和玉树M7.1地震数字化流体前兆观测资料,对比研究了五里营井流体在2次强震中的响应差异.结果显示,流体异常响应灵敏度与地震震级和观测点震中距有一定关系,地震震级越大,观测点距离震中越近,流体异常响应越灵敏.2次大震前流体前兆都观测到氦气释放活动最先出现异常反应,其释放强度与震级有关,震...

| Abstract: | The precursor response characteristics of digital fluid caused by Wenchuan M 8.0 and Yushu M 7.1 earthquakes are studied,and the response difference of the observations of Wuliying Well to the two strong earthquakes is compared.The result shows that the abnormal fluid response has a certain relationship with earthquake size and epicenter distance.The greater the earthquake,and the closer to the epicenter from the observatory,the more sensitive the response will be to fluid anomalies.Abnormal Helium release ... |
