The weather pressure is low.

Gloomy weather and low air pressure cannot directly predict the occurrence of earthquakes. Earthquake is a natural phenomenon caused by the change of geological structure of the earth, and its occurrence is not directly related to weather and air pressure.

However, some studies show that some seismic activities may be related to weather and climate conditions. For example, some seismic activities may be affected by rainfall, changes in groundwater level or stress accumulation in seismic zones. In some cases, these factors may increase the risk of earthquakes.

However, these relationships do not directly predict the occurrence of earthquakes, but provide some background information about possible earthquakes. Therefore, if you are worried about the possibility of an earthquake, you'd better rely on the official information and guidance provided by professional earthquake monitoring institutions and local governments.
