The U.S. Geological Survey's website states it in no uncertain terms: There is no such thing as "earthquake weather."  Yet, from at least the time of Aristotle, some people have professed links between atmospheric conditions and seismic shaking. For the most part, these hypotheses have not held up under scientific scrutiny and earthquake researchers have set them aside as intriguing but unfounded ideas. However, in the last decade new efforts to identify effects of weather-related, or in some cases climate-related, processes on seismicity have drawn new interest.
