All this reminds us that we must pay attention to earthquake disaster prevention. If we can know more about earthquakes and make more preparations before earthquakes occur, we will be able to reduce losses by one point when earthquakes occur. In the past 400 years, there have been 22 such earthquakes, mainly in the first half of the century; There were few disastrous earthquakes in the 1970s and 1980s. In the past three decades, the population in western Taiwan has soared. If there is another similar earthquake, the disaster will be even worse. Unfortunately, the active period of earthquakes in the first half of the century will come again. It is necessary for us to pay more attention to earthquake disaster prevention to prevent it before it happens. The eastern part of Taiwan has the most earthquakes in the world. The importance of earthquake disaster prevention should not be less than that of the western region.
