I think you will find a possible answer in my signature link (look at the date it was posted)
Is this place near area 51? could be underground base if so.
so say so. cal. and the epicenter is reno. Pacific? or Mexico? North? 
If it turns out to be Volcanic, I would head away from Reno, which ever way would be fastest North or South. It all depends on where your at and relative to Reno, or technically Mugal, Nevada.
So if the wells and springs drop or dry up, you have maybe 72 hours before hell on earth. Lets hope nothing happens.
Note: If your in Sacramento or San Francisco that is the worst area to be at.
