Has anyone done a study comparing weather with devestating quakes, especially in California. The four big California quakes during my lifetime have all occured on cloudless days, above normal temperatures influenced by a high pressure ridge off the coast. The same weather conditions existed for the 1906 quake in San Francisco. I don't have the weather conditions for the 1933 Long Beach quake. With the exception of Loma Prieta, all the big California quakes happened in the early morning between 4:30 and 6:30. Loma Prieta happen just after 5 pm, thus all the big california quakes have occured within a couple of hours of sunrise/sunset. Could weather/air pressure or the solar/lunar position influence quakes? Maybe I could go into the earthquake non-prediction business. I won't be able to tell you when we will have a major quake, but I can say it won't be at 12 noon on a cold, cloudy or rainy day.
