How do you know MineralMan? Just because no one has proven a relationship between weather and earthquakes doesn't make it an impossibility. No one seems to have carefully studied the relationship between earthquakes and tides/moon phases before Jim Berkland did, and he seems to be on to something. (Note that the Parkland quake has occurred during a full moon at high tide.)
Well. let's see. In central CA today, there was a major on shore push of the marine layer, breezy, with coastal drizzle. Not exactly the warm and still conditions of so called earthquake weather. Someone mentioned they had "earthquake weather" in San Diego - only problem is, San Diego is over 300 miles south of the area affected by this quake.
Changes in atmospheric pressure have no effect on the parts of the earth where earthquakes begin. There is no such thing as "earthquake weather."
P.S. Berkland is a fraud.
