There are claims that more earthquakes happen on hot, dry days - so-called "earthquake weather." But studies that have shown no tie between seismic activity and months or seasons.
The forces that drive weather are not likely to have much of an effect on the movement of continental plates several miles below the surface, geologists say.
Even the tide-causing gravity of the Moon and Sun apparently play no role in the onset of an earthquake. Scientists have looked for a seismic relationship to the tides, but nothing has been seen except for a small correlation with aftershocks in some volcanic regions.
