Why is there no earthquake warning in Fengfeng mining area?

The situation of crustal movement is too complicated. According to inquirer Baba in official website, the biggest reason is that the movement of the earth's crust is too complicated and irregular to follow, which is different from the weather forecast through satellite cloud images. In earthquake-prone areas, various underground movements are quite frequent. At the present level of technology, scientists simply can't tell which movement is an earthquake.
