What about 7?
Does California care about earthquakes below a 5.7? >

under 4.0 = "was that an earthquake?"
over 4.0  = "that was definitely an earthquake."
over 5.0 = getting up off the couch in case it gets bigger
over 6.0 = getting into the door jamb out of bad 1980s instinct
but that's just me. can't fight that stupid 80s instinct to get in the fucking door jamb
