Is it windy and cloudy every day an earthquake?

It's windy and cloudy every day-this is a common weather change, not an earthquake.

Earthquake, also known as ground motion and ground vibration, is a natural phenomenon in which the earth's crust vibrates in the process of rapid energy release, and seismic waves will be generated in this process. On the earth, plates collide with each other, resulting in dislocation and rupture at the edges and inside of plates, which is the main cause of ground vibration (that is, earthquake).

According to the magnitude classification can be divided into:

Weak earthquake: earthquake with magnitude less than 3;

Sensible earthquake: an earthquake with magnitude equal to or greater than 3 and less than or equal to 4.5;

Moderate earthquake: an earthquake with a magnitude greater than 4.5 and less than 6;

Strong earthquakes: earthquakes with magnitude equal to or greater than 6, among which those with magnitude greater than or equal to 8 are called giant earthquakes.
