I guess it's ok to make a few jokes after the facts, especially if no one got hurt or killed.
I experienced a strong one when I was 15-years-old. Don't remember the magnitude but it must have been close to an 8 on the Ritcher scale. I remember, though back then being measured on a different scale, perhaps the Mercalli scale. I also remember being an ondulating one as opposed to an oscillating one and me and family living in a tent city for about a month and a half. It scared the bejesuses out of me. Imagine being in the middle of the street (you had to walk as far away from buildings) and waving from side to side or shaking in your bed and things falling off shelves and the house squeaking. Well, during those first shakes I don't think joking about was appropriate just as I don't think it's appropriate to joke about this one w/o knowing of the consequences. But that's me and that's how I feel.
Btw, in the one I experienced hundreds of people died.
Looks like Japan got hit pretty hard after all.
Sometimes making a joke about something is the only way to cope.
My son was in Japan for awhile. He has stories too. He's in San Diego now:'(
Where was the earthquake you experienced?
