Many people ask why a 4.3-magnitude earthquake occurred in Fuyang, not in the traditional earthquake zone. In response to this question, Wang Xingzhou, director of the Anhui Earthquake Prediction Research Center, told the reporter that the epicenter was located in the northeast corner of the intersection of the east-west Linquan-Liu Fu fault and the northeast Wang Laoji fault, which is a normal phenomenon.

According to its introduction, there is no historical record of earthquakes in Fuyang area in history. "The earliest earthquake records can be traced back to 1644. The latest earthquake occurred in Lixin county of 1999, which is more than kilometers away from 10. There have even been two earthquakes of magnitude 6 or above near Fuyang 100 km. "

It is not uncommon for a small earthquake of magnitude 4.3 to cause death. "For example, the 20 12 Jiangsu Gaoyou M 4.9 earthquake also caused casualties."

The casualties caused by this earthquake are caused by many factors, such as the poor quality of some houses, the characteristics of the earthquake, and the unskilled application of hedging knowledge.

"In housing construction, seismic design is very important. Whether there are ground beams on the foundation of the house, whether the columns are reinforced concrete, the ring beams on the roof and the structure of the floor all have an impact on the seismic performance of the house. " Wang Xingzhou said, "However, in the vast rural areas, these designs were not considered when building houses due to reasons such as funds and building habits. This has buried many hidden dangers of earthquakes. "

Many people don't pay enough attention to the knowledge of shock absorption on weekdays, which leads to panic during the earthquake and aggravates casualties to some extent.

When talking about the large-scale house damage caused by small-scale earthquakes, Wang Xingzhou explained that the degree of earthquake damage is not linear with the magnitude. "The comprehensive determination of factors such as magnitude, focal depth, earthquake type and surface coverage requires collective analysis of specific situations."

"The focal depth is shallow and the destructive power will be greater. However, if the local surface coverage is thick, the attenuation of seismic energy will be relatively large, which will weaken the impact of the earthquake. "

When talking about the comments circulating on the Internet that there will be a major earthquake in Fuyang, Wang Xingzhou made it clear that "the rumors are not credible."

This earthquake is an isolated one. After this type of earthquake, there are few earthquakes, and even many will not have subsequent aftershocks. According to the analysis of observation data, there is probably no earthquake in Fuyang after the earthquake.

Since the Wenchuan earthquake in 2008, the seismic activity in mainland China has entered a relatively frequent period, and there have been many earthquakes of magnitude 3 and 4 in Anhui in recent years, but these are normal plate movements, and it cannot be inferred that a major earthquake will occur.
