Earthquake weather is a type of weather popularly believed to precede earthquakes. From the ancient histories of Herodotus to the modern writings of David Lance Goines, the notion that weather can somehow foreshadow coming seismic activity has been the topic of much discussion and debate.

The USGS website states that, In the 4th century B.C., Aristotle proposed that earthquakes were caused by winds trapped in subterranean caves. Small tremors were thought to have been caused by air pushing on the cavern roofs, and large ones by the air breaking the surface. This theory led to a belief in earthquake weather, that because a large amount of air was trapped underground, the weather would be hot and calm before an earthquake. A later theory stated that earthquakes occurred in calm, cloudy conditions, and were usually preceded by strong winds, fireballs, and meteors. A modern theory proposes that certain cloud formations may be used to predict earthquakes, however, this idea is rejected by most geologists

Geologists maintain that there is no connection between weather and earthquakes. They are the result of geologic processes within the earth and can happen in any weather and at any time during the year. Earthquakes originate miles underground. Wind, precipitation, temperature, and barometric pressure changes affect only the surface and shallow subsurface of the Earth. Earthquakes are focused at depths well out of the reach of weather, and the forces that cause earthquakes are much larger than the weather forces. Earthquakes occur in all types of weather, in all climate zones, in all seasons of the year, and at any time of day.
