N Lakeport, CA / Light shaking (MMI IV) / 2-5 s : Cats ran away, a sudden jolt, that sound again. I rolled off my bed and lay my chest towards the ground. Another jolt as I whimpered in fear with tears streaming down my face. Could this be the one that sends magma spewing from clear-take Volcano? The wife knelt down and slap me (she slaps hard) and said, "you know what that one was for!" I lay, post crying sniffles for about an hour. | 2 users found this interesting.
