Is there an earthquake in Guangdong?

Earthquakes are the inevitable result of the internal movement of the earth. Through precise instrument measurement, there are 5 million earthquakes that can be detected every day in the world, but they are all too weak to be detected by instruments that are not precise enough. People need 3-4 degrees to feel it without the help of instruments, and buildings above level 5 will be damaged. The so-called "level" is a measure of the energy released by vibration. The energy released by an earthquake of magnitude 5 is equivalent to 1 bomb, magnitude 6 to 10, magnitude 7 to 100, magnitude 8 to 1000, and magnitude 9 to 10000. Since the Xinfengjiang Reservoir (now called "Lvwan Lake") was established in Heyuan in the 1950s, there have been earthquakes of magnitude 1 time in Guangdong almost every year, which can be felt by ordinary people, but there has not been any damage, which effectively released the geostress, prevented it from accumulating into a major earthquake, and protected the whole eastern Guangdong (including Heyuan, Meizhou, Huizhou, Shenzhen, Hong Kong, Guangzhou and Shanwei).
