Since 1970, there have been no earthquakes of magnitude 4 or above within the epicenter 100km, but there have been many earthquakes of magnitude 3.
At 5: 45 on March 10, 2008, an earthquake of magnitude 4.3 occurred at the junction of Fengqiu, Changyuan and Lankao in Henan (35.0 north latitude, 1 14.7 east longitude) (this earthquake was reported as magnitude 4.8).
This area is a region with low seismic activity in China, and the level of seismic activity is weak. Judging from the seismic activity, the Zhoukou M 4.7 earthquake occurred in an area with a low level of seismic activity. Most of the moderate and strong earthquakes in this area in history are single, and it is unlikely that earthquakes of magnitude 5 or above will happen again in the near future. Judging from the above historical data, there has never been a major earthquake in Sanmenxia area.
