There are many mountainous areas in western Sichuan, with basins in the middle and earthquake-prone areas, most of which are concentrated in the western mountainous areas. Inspired by the Tangshan earthquake, Sichuan archaeologist Lin Xiang found that high-rise buildings were affected by seismic waves and would fall towards the epicenter. From the perspective of archaeology, he inspected the well-preserved high-rise pagodas around Chengdu. All the major earthquakes in history came from the northwest, and there was no major earthquake in Chengdu's history.
Chengdu is not in the seismic activity zone and has excellent damping layer, so it is the most stable area. The earthquake zones of Longmenshan, Songpan and Mao Wen, which are closest to Chengdu, have the greatest impact on Chengdu, with the intensity of 7 degrees during the Wenchuan earthquake.
From the historical and geological point of view, it is unlikely that there will be a major earthquake in Chengdu in the next century or even centuries.
Moreover, all the buildings now built in Chengdu have earthquake prevention measures, and earthquake early warning technology is now built. Earthquake early warning technology is realized by using the basic principle that electromagnetic waves are faster than seismic waves. After the earthquake, the sensors close to the earthquake source quickly transmit the news of the earthquake to a distant place through electrical signals, so people far away from the earthquake source can take appropriate measures to avoid danger before the arrival of seismic waves.
Shortly after the M6 earthquake occurred in Changning County, Yibin, Sichuan Province on the evening of June, 2065438 17, Chengdu, more than 300 kilometers away, received an earthquake warning signal. This warning signal arrived in Chengdu about 60 seconds ahead of the earthquake wave. With the existence of earthquake warning signals, it is believed that the disasters suffered by a large number of earthquakes can be reduced, at least people can run to safety in advance and reduce the deaths caused by earthquakes.
