Yet another earthquake in Japan!
The experts predict in the coming weeks other replicas generated by the magnitude 9 earthquake that hit Japan on March 11. After this event all tectonic forces in the region have been disrupted, and these aftershocks are a kind of adjustment at regional level. But the powers of shocks will decrease with time.
In March, the biggest damage was done by the tsunami, no earthquakes.
I believe that Japan is well prepared for earthquakes. I hope it will go well. Good luck.
