First of all, I am asking this question from a very limited observation standpoint.

Why do the severe earthquakes always seem to happen in good weather (at the epicenter)? I personally can't remember an earthquake of a large magnitude in recent years that has occurred during the rain/snow. Most assuredly, I remember earthquake victims who were displaced from their homes then living outside exposed to the rain/snow that have followed the earthquake, but I do not remember hearing about a large earthquake occurring during a rainstorm/snowstorm.

I have not looked up any historical co-relations of these large earthquakes and the weather. I am strictly basing this on my very limited memory of large events in the news in my lifetime. And I've heard/read about earthquake weather -- hot, dry, possibly windy. But I've never heard anything about (large) earthquakes occurring during rain/snow storms. Do they happen then?
