Northern Sichuan lies in an area with high tectonic activity . In this region , the Tibetan Plateau abuts against the Yangtze Plate with immense pressure forming faults along the edges . Jiuzhaigou County is located in the Min Mountains , a range that was formed at the intersection of these faults . The devastating 1879 Gansu earthquake had its epicenter approximately to the east of where the 2017 Jiuzhaigou earthquake occurred . The mountainous areas to the south of Jiuzhaigou County were the epicenter of the 2008 Sichuan earthquake that resulted in tens of thousands of fatalities
