I have this program on my ipad that shows all the plates and when earthquakes happen, plus tornadoes and hurricanes. It's kinda interesting to look at it and see all the earthquakes that have been happening in Japan. A few days ago rumbles started in Myanmar, so I'm not surprised this happened. The ones in Japan have been getting fewer and farther between. So far today they've only had 3 that were above a 5. It looks like Myanmar is having aftershocks about every 2 hours. There was also a 5.2 today south of the Kermadec Islands.
