What happened to the Ya’an earthquake overnight?On-site direct hit experts talk about whether there are aftershocks
At 17:00 on June 1, an earthquake of magnitude 6.1 occurred in Lushan County, Ya’an City, Sichuan; at 17:03, an earthquake of magnitude 4.5 occurred in Baoxing County, Ya’an City. After the earthquake, the Sichuan Provincial Party Committee and the Provincial Government urgently deployed and mobilized, and rescue forces from all parties rushed to the epicenter.
Overnight, what happened to the Ya’an earthquake?Xinhua News Agency official accountAccording to the latest report, all forces rushed to help quickly, and the affected people were properly resettled.
At the resettlement site of Baoxing County Gymnasium, the reporter saw that the National (Sichuan) Emergency Medical Rescue Team has immediately set up triage points, divided treatment areas, and assisted in evaluating and disposing of the wounded. Relevant doctors of Ya’an People’s Hospital said that a total of 6 patients have been treated from Baoxing County, 5 of which are generally stable, and the other patient fell while running. Has returned to rest.
It is understood that at present, Ya’an City has organized more than 800 municipal-level reinforcements to carry out personnel search and rescue, wounded treatment, road rescue, and mass resettlement and transfer. The Sichuan Provincial Department of Finance has opened a “green channel” for fund allocation, and has urgently allocated 50 million yuan in earthquake relief funds for Lushan County and 50 million yuan in Baoxing County to support the two counties in ensuring emergency funds.
According to reports, the earthquake was located in the Longmenshan fault zone. The nearest fault is the Shuangshi-Dachuan fault, which is about 2 kilometers away. The focal mechanism is a thrust type. The earthquake occurred at the eastern boundary of the Bayan Har block, and the seismic activity was relatively strong in history.
The China Earthquake Network Center organized experts to study and analyze the seismic activity near Lushan, Sichuan. According to the characteristics of historical earthquake sequences, geophysical observation data, and a preliminary judgment, the earthquake is a main shock-aftershock type earthquake, and the aftershock area of Lushan will be in the short term. Another larger earthquake is unlikely.
According to @chinaseismic.cn quick report, in the past year, there were 79 earthquakes of magnitude 3 or above in Sichuan, including 61 magnitudes 3.0 to 3.9, 15 magnitudes 4.0 to 4.9, 1 magnitude 5.0 to 5.9, and magnitude 6.0 to 6.9. 2 times, 0 times above magnitude 7.0, the largest earthquake is this earthquake.
In addition, after the earthquake, China Earthquake Early Warning Network (trial operation) sent early warning information to Ya’an, Leshan and Meishan through the mobile app and early warning terminal. Netizens in Sichuan, Chongqing and other places said that TV sets and mobile phones have received earthquake early warning information, showing that the epicenter was located in Lushan County, Sichuan, and the early warning information came from the Chengdu Emergency Management Bureau.
Wang Tun, director of the Sichuan Key Laboratory of Earthquake Early Warning and Multi-hazard Early Warning Application Information Technology and director of the Chengdu High-tech Disaster Reduction Research Institute, also said that the earthquake was the result of aftershocks plus new energy accumulation, and cannot be simply understood as aftershocks.
After the earthquake occurred at 17:00 on June 1, Wang Tun and his team judged that a very small number of people would be injured and very few people would die. Judging from the current casualty situation, it is consistent with the original judgment.
Wang Tun and his team further judged that it is unlikely that the earthquake will cause more than double-digit deaths. “This is mainly due to the fact that after the (2008) Wenchuan earthquake and (2013) Lushan earthquake, local buildings are safer, emergency response capabilities and awareness of risk avoidance are getting higher. , played an important role in emergency hedging.”
