I was on holiday in California with my (then) Dutch girlfriend, soon to be first (now, ex-) wife in 1989 and we were staying just outside San Jose for a reason that defeats me. Anyway, she wakes me up in the middle of the night screaming with the hotel room wobbling from side to side (I remember to this day the painting on the wall penduluming). She eventually woke me up and I said "Go to sleep, it's probably just an earthquake" and went back to sleep. She was furious the next morning. Presumably all night actually but, as I said, I just went back to sleep so I wouldn't know. Two months later, the big one hit California.
That was quite a trip. We almost got hit by lightning at the Grand Canyon as well. I swear a lightning bolt hit the middle of the road, of all places, about 50 yards in front of us. First time I had ever seen a woman with a square mouth, frozen in shock. Never a dull moment with me around :)
