Figure 2
The active tectonic blocks, observation stations, and studied earthquakes in Qinghai province. The Bayan Har, Qaidam, and Qilian blocks are marked with grey, green and yellow, whose movements are indicated by hollow arrows. The earthquakes of magnitude 7.0 and above occurred on the Bayan Har block and the Ms ≥ 6.0 earthquakes in Qinghai province since 2021 are displayed with gray and red circles. Also shown in the Figure are the 7 hydrological and 2 geodetic observation stations discussed in this work. Earthquakes: HHXL8.1: 14 November 2001 Ms8.1 HohXil, YT7.3: 21 March 2008 Ms7.3 Yutian, WC8.0: 12 May 2008 Ms8.0 Wenchuan, YS7.1: 14 April 2010 Ms7.1 Yushu, LS7.0: 20 April 2013 Ms7.0 Lushan, YT7.3: 12 February 2014 Ms7.3 Yutian, JZG7.0: 8 August 2017 Ms7.0 Jiuzhaigou, MD7.4: 22 May 2021 Ms7.4 Maduo, MY6.9: 8 January 2022 Ms6.9, and DLH6.0: 26 March 2022 Ms6.0 Delingha.
