Well an aftershock rocked Japan in the last few hours. It happened last night at 3:30 am. It was not very strong but strong enough to wake me up. But it didn't wake me up all the way like the strong one. It woke me up enough to be mad and in my semi-awake state yell "Go away earthquake, I am trying to sleep." It stopped and I fell alseep again. Here is the info on it
I am not quite so scared of them, having felt some of the minor ones and now single handedly intimidating an earthquake into stopping.
