Right after it stopped I told my assistant who’s never experienced an earthquake I guestimated 5.7. Just threw it out. Guess they upgraded to 5.8 so our guesses average to perfection :)
Ha Ha! The person I was working with hadn’t been through one either! She didn’t like it much. I figure if you feel it but can still walk around, it’s between 4.0 and about 6.3.
