Discussion on the latest surface ruptures near the Zhonggu village along the Selaha segment of the Xianshuihe fault zone

Dizhi lixue xuebao, 2022
The Selaha segment of the Xianshuihe fault zone was the seismogenic fault of the 2014 Kangding MS 6.3 earthquake. This segment has been considered as one of the most dangerous areas for surface rupture-induced earthquakes with a magnitude of M≥7 due to ...
