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

  • 图  1  洱源井的空间分布图

    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;震源机制解来源于哈佛大学(Dziewonski,Ekström,2021);地质单元与河流数据来源于MapSIS软件(蒋骏等,2000

    Figure  1.  Spatial distribution map of the Eryuan well

    The fault data are revised from China Active 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
