It's an easy prediction. It's called the ring of fire for a reason. I remember my first earthquake living in Portland. I wasn't expecting any such thing, I thought it was my neighbors making noise until the next day, even yelled at them to keep it down. I had work to do the next day!
Seriously though people please give a few bucks to help Japan. I'm going to be helping soon through eBay sales so make like me and rule.
