Before the earthquake comes, there may be some abnormal situations, such as cracks in the ground, abnormal groundwater, and animals will show panic. After all, before some strong earthquakes, animals will have some abnormal behaviors. The main reason is that animals have retained some organs that are relatively sensitive to earthquakes in the process of evolution.
01
As we all know, well water is actually connected to the ground. In general, before an earthquake comes, well water will overturn, bubble and even appear to swirl and so on. Of course, some fracture surfaces are constantly rubbing, at this point the delay may dissolve directly into the water.
02
During an earthquake, the ground will crack and contact with the earth gas. In fact, in many areas, due to the impact of the surface rock fracture, there will be a particularly large crack on the grou
03
In case of earthquake, near the epicenter may appear rupture, even because of the friction and piezoelectric effect and form sound and light, we call it a gigantic.
