BBC News reports that some seismologists who study Japan believe that the recent 9.0 earthquake off the coast of Eastern Japan may have slightly increased the chances for a large earthquake in the Tokyo area. I pray it does not happen in our lifetime but unfortunately it will happen. People and governments should be aware of that. The map below shows the plate boundaries around Japan. As you can see, Tokyo is right at the juncture of three plates, the Pacific Plate, the Eurasian Plate, and the Philippine Plate. You could say that Tokyo is in the middle of a gigantic crunch zone.
