Heaven is easier than earth. Why is the earthquake a worldwide problem?

This power is enormous, and whenever various natural disasters occur, it will always cause huge casualties and property losses to mankind. Therefore, human beings are particularly afraid of all kinds of natural disasters and man-made disasters, and man-made disasters are good, that is, all kinds of natural disasters. Earthquakes, in particular, are the most elusive among natural disasters. In the past, people thought that earthquakes often occurred in the earthquake zone, but in recent years, some earthquakes occurred outside the earthquake zone, which made people find it difficult to figure out the law. The reasons are as follows.

First of all, the seismograph itself is very expensive. Just some seismometers commonly used in our daily life, and their cost is very expensive. It is difficult to install such seismographs in every area. In fact, there are not many instruments installed at one time in this area in China, so how to make accurate and timely measurements is also a huge problem. As far as China is concerned, it is impossible to install seismographs in every region, let alone some other backward countries.

Second, earthquakes have become more and more frequent in recent years. Secondly, another reason is that the comments and frequency of earthquakes in recent years are hard to prevent. At the same time, it also caused some types of harm, and the casualties and property losses were terrible. More and more frequent earthquakes make people feel scared and think that this earth is very dangerous. So it will become a worldwide problem.

Third, there is no regularity. A very important reason is that earthquakes do not follow the law. In the past, people thought that some plate boundaries were prone to earthquakes, but now many non-plate boundaries are also prone to earthquakes. That is to say, many countries have been discussing and studying the occurrence law of earthquakes, so it is also one of the world's problems.
