Oh, you experienced and knowledgable people...

However, I also feel obligated to point out that running out of the house is a bad idea!

Even if you're on the second story and the rattling building might collapse into the downstairs part, crushing you all beneath a huge pile of rubble, when outside is a magical fairyland of trees and veggie gardens and sweet sweet safety, unlike this inside terribly-quakey bit with all its shakiness?

Thanks for the advice!
