"Hope it's not a foreshock!"
Probably not. A 4.+ earthquake is not a big deal. There are a few every month, somewhere in CA.
Yeah, a 4.+ earthquake is not a big deal, unless it's a foreshock to an 8.0!
Er, I live in fly over country and we don't normally have earthquakes so I need to ask: is there really such a thing as foreshock???
It may have been , since link just above to info on 4.9 at 1:53 this afternoon.
