What kind of weather abnormalities occurred before the Sichuan earthquake? What should Sichuan consider first?

Before an earthquake, there may be some signs due to plate movement and geothermal release. For example, there may be convective clouds caused by geothermal heat (generally small in scope), rapid changes in groundwater levels, warming of water temperatures, abnormalities in underground and water animals, etc. Due to limited scientific detection technology and complex underground physical phenomena, earthquakes cannot be predicted.

When there is an earthquake, there will be some corresponding phenological phenomena. On the other hand, when there are those phenological phenomena, there may not necessarily be an earthquake, or they may even have nothing to do with earthquakes.

The weather and climate you mentioned are abnormal, in fact this is the case in many places now. Climate anomalies are normal phenomena of atmospheric movement.

Meteorologists and seismologists are paying close attention to natural phenomena every day, so don’t worry.
