I have not seen much in their reports that gives a geographical break down.
However, there was an article in their Investors Newsletter (p4) of Sep 2012 which discussed the strategy on Domestic Insurance. In the article they indicated that over the last 3 years they have been trying to get away from accepting policies from just anywhere, and focussing on "insuring owners of newer homes in metropolitan areas".
On this basis, they should be reasonably well covered.
At the worst, in some of the 2010 and 2011 catasrophes, Calliden ended up with 1% of the claims. If you take the indicative 100 houses to date damaged/destroyed, then their exposure could be say $250,000 to $750,000, so hardly material.
However my heart goes out to those effected. It must have been terrifying
