Why is cool weather related to earthquakes?

Cool weather is not directly related to earthquakes.

First of all, the cool weather is mainly due to the temperature drop, which leads to the condensation of water vapor in the air into water droplets or ice crystals, forming clouds and rainfall. Earthquakes are caused by movements inside the earth.

But before some earthquakes, there will be some natural anomalies, such as weather anomalies and animal anomalies. But these anomalies are not necessarily directly related to the occurrence of earthquakes, and may also be caused by other natural factors.

So there is no necessary connection between cool weather and earthquakes.
