<p>Though I imagine it's unlikely there is any significant correlation because daily and annual temperature variation really only impact a fairly shallow layer of the crust, I wondered whether the actual data backs that up.  I could envision a few unlikely causes, such as the expansion\contraction, rainfall amounts, or crazy things like the little differences in earth-sun distance.  So what say you?</p>

Are there any seasonal or diurnal trends in earthquakes?
