Clear skys here. It's cold, however. I remember seeing some weird weather the night before the Whittier Narrows quake. I was living not far from the epicenter at the time. We had a sudden gust of warm wind carrying ice-cold rain. A co-worker's wife joked that it was "earthquake weather". The next day, he told her not to make jokes like that.

Thats why I asked. Wind has come up here in last 20 mins or so. Seems that the weather has gotten weird a few times right before a quake. Another interesting note, I live right under the departure path of Lindbergh Field, about 1 mile from the airport in Point Loma, and from the time this thread was posted, was about 45 mins before another plane took off. Not normal, had us wondering.

Here is the Shake map .

Didn't feel a thing down here in orange county >

But I thought I heard thunder about the time this happened and went outside and could not see anything that would account for the noise.

The moon was visible through the clouds and there was a light mist and could not see any clouds that might account for the noise.

"Earthquake weather"

Think about the physics. How could any atmospheric conditions affect fault planes at 45,000 feet below the earth's surface? There might be something to "earthtides" and minor quakes, but no valid statistical study has ever concluded that "great quakes" (those with a Richter magnitude over 8.0 and over) are associated with phases of the moon, planetary alignments, or weather patterns.

In fact, if you look at the forces generated by plate tectonic processes, they dwarf the others mentioned above.
