Why is there an earthquake when the weather is cold?

Earthquakes are mainly caused by crustal movement and have nothing to do with the hot or cold weather.

The lithosphere on the earth's surface is called the crust. Earthquakes are called earthquakes, which are caused by the rapid rupture and dislocation of the crust and strata after being stressed. Earthquakes caused by geological tectonic activities are called tectonic earthquakes; Earthquakes caused by volcanic activity are called volcanic earthquakes; Earthquakes caused by the collapse of solid rocks (especially limestone) are called collapse earthquakes. Earthquake is a very common and common natural phenomenon. However, due to the complexity of the crustal structure and the non-intuition of the focal region, there is still no satisfactory answer to how earthquakes, especially tectonic earthquakes, are bred and occurred, and what are their causes and mechanisms. But at present, it is recognized by scientists that tectonic earthquakes are caused by crustal plate movements.

Because the earth's rotation and revolution are endless, and its internal materials are constantly differentiated, the crust around the earth's surface, or lithosphere, is also constantly generated, evolved and moved, which has contributed to the global crustal tectonic movement. Scientists have experienced long-term observation, description and analysis of crustal structure and land-sea changes, and have successively formed different hypotheses, ideas and theories. The theory of plate tectonics, also known as new global tectonics, was formed in the late 1960s and has been accepted by geoscientists.
