Nandu News reporter Dong Xiaoyan on the evening of the 12th, a magnitude 5.2 earthquake occurred in Yulin, Guangdong Province, many places felt the earthquake. According to @China Seismological Network Quick Report: China Seismological Network officially determined that a 5.2 magnitude earthquake occurred at 22:55 on October 12 in Beiliu City, Yulin City, Guangxi (22.18 degrees north latitude, 110.51 degrees east longitude), with a focal depth of 10 km. According to the quick report of China Seismological Network, the epicenter of the earthquake is located at the junction of Guangxi and Guangdong, and there are obvious earthquake sensations in more than two provinces.
What are the causes of the Yulin earthquake? Why are there many earthquakes in Guangdong? Will there be any earthquakes in the future? Nandu correspondent contacted experts from Guangdong Seismological Bureau to explain the earthquake situation in detail.
What are the causes of the Yulin earthquake?
Expert: There are conditions for the formation of faults here. Small earthquakes occur frequently in recent half a year.
In the past six months, we have been paying more attention to this area, and there are indeed some anomalies. Deng Zhihui, director of the Forecasting Research Center of the Guangdong Seismological Bureau, told Nandu reporters that some conditions for the formation of fault structures had been discovered recently at the junction of Guangdong and Guangxi. Simply put, the crustal force is concentrated here, and the energy will accumulate here, which will easily lead to the enhancement of small and medium-sized seismic activity.
Deng Zhihui said that in recent years, there have been more earthquakes at the junction of the two places, with high frequency of earthquakes of magnitude 3 and 4. Especially in Western Guangdong and Eastern Guangxi, but it is not necessarily said that the seismicity will increase, then there will be large earthquakes, still need to continue monitoring attention.
Why is the earthquake strong in Guangdong?
Expert: The earthquakes are felt at the junction of Guangdong and Guangxi.
The epicenter of the 5.2 magnitude earthquake in Yulin, Guangxi, lies on the border between Guangdong and Guangdong. Many netizens in Foshan, Shenzhen, Guangzhou and Guanguan of Shandong have feedback of earthquake feeling.
Why is the earthquake strong in Guangdong? In response to the queries of many netizens, Deng Zhihui told reporters in Nandu that Yulin is relatively close to many places in Guangdong Province. It is normal for some areas of the province to have slight earthquake sensation, and citizens need not worry too much. ?
Will there be earthquakes in the future?
Expert: Not excluding the possibility of moderate to strong earthquakes, the public still need to take precautions.
After the earthquake, there is a discussion on the topic of there will be another M 2 aftershock on the Internet. Deng Zhihui said that the current network discussion on whether aftershocks will occur has no basis. Generally, after moderate and strong earthquakes, there will be smaller aftershocks, and the relevant technical departments can indeed predict the extent through real-time data and data.
With regard to the earthquake, we are currently conducting networking meetings with Beijing and Guangxi. From now on, we have information to analyze it. Next, there may be aftershocks, but the intensity will be lower and the impact will be smaller. Citizens need not panic. ?
But Deng Zhihui reminded the public that they still need to take precautions. According to the data available at present, the distribution and tectonic environment of the earthquake are not very different. However, due to the recent active crustal movement, it is not excluded that moderate-strong earthquakes may occur, or should be lower than the magnitude of 5.2, the public still need to take precautions.
