At 01:28 on June 10,2022(Beijing time),an earthquake of magnitude 6.0 occurred in Maerkang city(32.25°N,101.82°E),Sichuan Province. The China Earthquake Early Warning Network released the first early warning results in 9.0 seconds after the earthquake,and released the automatic quick report results in 3 minutes after the earthquake. The official quick report results was released by China Earthquake Network Center in 7 minutes after the earthquake. Then,together with other institutes,the China Earthquake Network Center produced emergency production,including source parameters,historical earthquakes,seismic tectonics,focal mechanism,aftershock location,and estimated intensity,which gives a preliminary constraint on seismogenic structures of faults. The results show that the earthquake occurred in the Songgang fault zone,located in the Aba sub-block at the eastern part of the Bayan Har block on the Tibet plateau. The focal mechanism solutions indicate that the mainshock occurred on a strike-slip fault and the focal mechanism of the large aftershocks is similar to that of the mainshock. Based on the intensity rapid report,the intensity of the extreme earthquake area reaches Ⅸ degree,with a total area of about 70km²,and the total area of Ⅷ degree and above is about 734km²,which is from 7 towns involved.
