An aftershock occurred after the Tangshan earthquake. Will there be a big earthquake in the future?

On the morning of July 12, an earthquake with a magnitude of 5. 1 occurred in Tangshan, Hebei Province, and the Beijing-Tianjin-Hebei region was obviously shocked.

According to the news from the Seismological Bureau of Hebei Province, the earthquake occurred in the old earthquake area of Tangshan, and the nearest fault has not been named, about 6 kilometers away.

Subsequently, 33 aftershocks occurred continuously, but the magnitude was small and the sense of shock was not obvious.

What is the background of this earthquake?

5. The magnitude of1is not a strong earthquake, and no casualties have been caused at present. Maybe it happened in other places, which won't attract so much attention, just because the earthquake happened in Tangshan.

1976 Tangshan earthquake, I believe everyone is too unforgettable.

The earthquake occurred in the aftershock area of Tangshan earthquake with magnitude 7.8 on 1976.

The earthquake activity in the aftershock area of Tangshan earthquake is very rich, showing a fluctuating attenuation state, and there are still earthquakes of magnitude 4 and 5.

For example, an earthquake of magnitude 5.0 1995 occurred in guye district, Tangshan on June 6, and an earthquake of magnitude 5.012 occurred at the junction of Tangshan municipal district and Luanxian county on May 28.

Will there be a big earthquake in the future?

According to the analysis of experts' consultation, it is unlikely that an earthquake of magnitude 5 or above will occur in the original earthquake area recently.

However, even the authoritative experts of Seismological Bureau can only talk about the possibility. Judging from past experience, the possibility of a major earthquake is very small.

First, after a major earthquake, there will be no major earthquake for a long time (at least one hundred years), because the energy release of crustal movement has been completed, and it will take time to re-accumulate.

This is based on science, and past experience also supports this judgment.

Second, after 1976, there were many small-scale earthquakes in Tangshan area, which was equivalent to "flood discharge" for many times. The cumulative strength of the earth's crust should not be enough to support the occurrence of a major earthquake.

How to deal with the danger before the earthquake?

1, turn on the TV

Although the earthquake is unpredictable, it can be warned. Now Tangshan 5. 1 earthquake is included, and the early warning mechanism has all played its role.

At that time, the TV will raise the volume and warn that the earthquake wave will arrive in 30 seconds, which will allow us to respond effectively in advance.

Step 2 conduct exercises

When I was studying at school, I believed that all the teachers had organized earthquake drills.

In the family, it is also necessary to plan the hiding place and escape route in advance.

Once you hear the warning, immediately follow the plan to avoid and escape.

3. Systematically learn the knowledge of earthquake prevention.

How to avoid, how to escape, what preparations can be made, have quite professional knowledge, even if your location may not be an earthquake-prone zone, it is recommended to learn.

Generally speaking, earthquake early warning is not earthquake prediction, and earthquakes are unpredictable, so active preventive measures should be taken.
