At 17:00 on June 1, 2022,Beijing time,an earthquake of magnitude 6.1 occurred in Lushan county(30.37°N,102.94°E),Sichuan Province. The China Earthquake Early Warning Network released the first early warning results in 5.7 seconds after the earthquake,and the automatic quick report results in 3 minutes after the earthquake. The official quick report was released by China Earthquake Network Center in 9 minutes after the earthquake. The overall emergency production accompanied with other institutes includes 9 types of data such as source parameters,historical earthquakes,seismic structures,focal mechanism,aftershock location,and estimated intensity. The results show that the earthquake occurred in the Longmenshan fault zone,at the intersection of many tectonic units,such as the Bayan Har block of the Qinghai-Tibet plateau,the Sichuan-Yunnan block,the Minshan structural belt,and the Sichuan-Yunnan structural belt. The focal mechanism solution indicates that the earthquake is from a thrusting event,and the precise location of aftershocks shows that the aftershocks are distributed in a near-NE direction,which is basically consistent with the fault trend in the epicenter area. Intensity Rapid Report speculates that the intensity of the extreme earthquake area reaches IX degree with a total area of about 2km²,and the total area of VIII degree and above is about 197km²,which is from five towns involved.
