Research Center, said, "The overall level of seismic activity in the area of Rongxian County, Zigong, where three consecutive earthquakes of magnitude 4 or higher occurred, is low. According to current research, the earthquakes that occurred were all tectonic earthquakes triggered by natural causes. No local tectonic base and gestation conditions exist for destructive earthquakes of magnitude 6 or higher. The main reason for the high interest in earthquakes in this region is related to the high population density in the area. For buildings with adequate fortification standards, earthquakes of magnitude 4 or so generally do not cause major damage."

271:, there are nine smaller-scale ruptures within 100 km of the epicentre. Since the Sichuan earthquake network began observing earthquakes in 1970, five earthquakes of magnitude 4.0 or greater within 50 km of the epicentre have occurred. The largest earthquake of magnitude was a 4.8 magnitude earthquake that occurred on March 29, 1985. Since the Sichuan region was in a relatively active period of seismic activity at the time of this earthquake's occurrence, Rong County has also experienced continued active small earthquakes in recent years.

At 0:30 a.m., the next morning, a team of experts from the Ministry of Emergency Management, led by Yu Shuming, deputy director of the monitoring and forecasting division of the China Earthquake Administration, arrived at the disaster area in Rong County, and a working meeting was held at the on-site command of the Sichuan Provincial Earthquake Bureau.

Shuidagou Reservoir in Gao Shan Town. It is estimated that this earthquake caused a total direct economic loss of 13.99 million RMB.

Although the magnitude of this earthquake was not large, there were casualties. According to He Yulin, a senior engineer at the
Sichuan Earthquake Bureau's Engineering Seismology Research Institute, casualties occurred because some old buildings in the area did not meet the current seismic protection

Rongxian, Zigong City, Sichuan Province, at a depth of about 5 km. According to the investigation of Zigong City Earthquake and Disaster Prevention and Mitigation Bureau at that time, the earthquake was strongly felt in Rong County. There were isolated cases of cracking of houses

After the earthquake, the
Sichuan Province Earthquake Bureau activated a Level III emergency response. At around 14:00 on the same day, a 20-member field team led by Lei Jiancheng, deputy director of the Sichuan Earthquake Bureau, went to the Rongxian disaster area to investigate . On the same day,
