A magnitude 3.0 earthquake occurred in Xinmi, Henan Province. What caused the earthquake?

A magnitude 3.0 earthquake occurred in Xinmi, Henan Province. Although the intensity of the earthquake is not great, it has also had a certain impact on people's production and life. The main reason for the formation of earthquakes is the movement between continental plates. The mutual extrusion between continental plates has caused the formation of earthquakes, which may not have much impact on the whole surface, but in front of nature, human beings are very small, so a slight earthquake will also have a serious impact on people's production and life. Therefore, when the earthquake comes, we must actively take measures to avoid risks and protect our own safety to the greatest extent.

1. An earthquake of magnitude 3.0 occurred in Xinmi, Henan Province. According to the monitoring by the Seismological Department of Henan Province, at 2 o'clock in the afternoon of September 20th, 2002 1 21year, the existence of seismic waves was detected in xinmi city, and an earthquake of magnitude 3.0 occurred in xinmi city. The earthquake of magnitude 3.0 is not very serious, and the sense of earthquake felt by human body is not very strong. People living in Zhengzhou are close to Xinmi, but they don't feel the shaking obviously.

Second, the cause of the earthquake is the movement of the continental plate. Many people may be suspicious of the earthquake in Henan, because Henan is located inland, not where the continental plates meet, and relatively speaking, it is not a place where earthquakes occur frequently. But at the same time, we should also know that Xinmi is basically a zone surrounded by mountains. The formation of mountains is due to the extrusion between plates, so it is normal to have earthquakes occasionally.

Third, when the earthquake comes, people should do a good job of avoiding risks. Man is very small in front of nature. According to the current technology, there is no way to predict earthquakes in advance, but when an earthquake occurs, we should take some positive measures, such as going to an open place and finding a hard triangular object to hide if it is indoors. Pay attention to safety after the earthquake, and try to avoid potential safety hazards caused by aftershocks.
