Earthquake!!!

There was just a pretty strong Earthquake! In Japan's classification, it was a level 4 where I live, and a weak level 5 in the center. The Japanese system is based on what is felt by people, so a one is weak, felt be people that aren't moving. Level 2 rattles doors and windows. Level 3 shakes buildings and rattles things loudly. 4 is supposed to shake buildings strongly, knock over objects, splash water out of water holding containers, and cause people to panic and run outside, while five can cause cracks in walls. I would say it was a weak 4 where I live since nothing fell over, but I could defiantly feel my apartment building swaying. The TV says that Tokyo and Yokohama were level 4. I think I'll live in a reinforced cement building next time I move.
