 China Seismological Bureau: There is little possibility of more earthquakes in Xingwen, Sichuan Province in recent days.


At 12:46 today (December 16), a 5.7 magnitude earthquake occurred in Xingwen County, Yibin City, Sichuan Province, with a focal depth of 12 km. According to the official Weibo news released by Xingwen, as of 16:00, a total of 10 people were injured in the county, all without life-threatening. Reporters learned from the China Seismological Bureau that, after preliminary study and judgement by experts, there is little possibility of more earthquakes in the original earthquake area in recent days, but there is the possibility of sensible aftershocks.

According to reports, the preliminary focal mechanism solution results show that the earthquake is a strike-slip earthquake, that is, an earthquake occurring on strike-slip faults. According to experts from China Seismological Bureau, the earthquake is located in the southeastern part of Sichuan Province. Structurally, it belongs to the boundary area between Sichuan-Yunnan block and South China block. There are many faults nearby.

It is reported that the region near the epicenter of the earthquake has been relatively active in the history. Since 1900, 15 earthquakes with magnitude 5 or above (including aftershocks) have been recorded, including 13 earthquakes with magnitude 5, 1 earthquake with magnitude 6 and 1 earthquake with magnitude 7.1, the largest of which was the Dabei earthquake with magnitude 7.1, about 90 km away from the earthquake, which occurred on May 11, 1974, and the closest was August 2, 1973. The earthquakes of M 5.4 in the northeast of Yiliang, Yunnan, are about 50 km apart, and the latest one is the Yanjin earthquake of M 5.1 in Yunnan on August 25, 2006. Recent small and medium-sized earthquakes in this region are also more active. On January 28, 2017, a Yunlian M4.9 earthquake swarm occurred. Experts from the China Seismological Bureau said that, on the whole, because of the deep focal depth, large sensible range and small instrument intensity near the epicenter, it was considered that the earthquake was a tectonic earthquake, and there was little possibility of more earthquakes in the original seismic area in recent days, but there was a possibility of sensible aftershocks.
