The anomaly characteristics of water temperature in the Eryuan well before the 2021 Yangbi MS6.4 earthquake in Yunnan,China

  • 图  1  洱源井的构造位置及附近的地震分布

    断层数据据中国活动构造图(邓起东等,2007)修改补充;地震目录引自中国地震台网中心;震源机制解源于哈佛大学(Dziewonski,Ekström,2021);地质单元和河流数据源于MapSIS软件(蒋骏等,2000

    Figure  1.  Tectonic position of the Eryuan well and the distribution of nearby earthquakes

    The fault data are revised from China ative tectonic map (Deng et al,2007),earthquake catalogue are from China Earthquake Networks Center,focal mechanisms are from Harvard University (Dziewonski,Ekström,2021),and geological units and rivers refer to MapSIS (Jiang et al,2000)

    Figure  3.  Variation of water temperature in the Eryuan well (a) and M-t map of MS≥5.0 earthquakes with epicenter distance from the Eryuan well below 100 km (b) during the period from October 13,2015 to August 21,2021
