Pinyin

According to statistics, more than 5 million earthquakes occur on the earth every year, that is, tens of thousands of earthquakes occur every day. Most of them are too small or too far away for people to feel; there are about ten or twenty earthquakes that can really cause serious harm to humans; there are about one or two earthquakes that can cause particularly serious disasters.

Earthquakes that people cannot feel must be recorded with a seismograph; different types of seismometers can record earthquakes of different intensities and distances. Thousands of various seismic instruments are operating around the world to monitor earthquake movements day and night.

Earthquakes

The current level of science and technology is still unable to predict the arrival of earthquakes, and earthquakes will also be unpredictable for a long time to come. The so-called examples of successful earthquake predictions are basically coincidences. Regarding earthquakes, what we should do more is to improve the seismic resistance level of buildings and prepare defenses instead of predicting earthquakes.
