No, it won’t warn you of an impending Earthquake, but it will make your bed shake like one. I guess you could show your bed partner how prophetic you are, but that would just be darn cruel. You know what else would be darn cruel? Setting this thing at max volume, which is 113 decibels (an aircraft taking off has a 100 decibel rating). Probably more effective than the Flying Alarm Clock or the Axbo.
