We have never experienced such a huge earthquake.
The epicenter distributes in a north-south direction with 500 hundred kilometers, and this epicenter in the Pacific Ocean is facing close to the north-eastern part of Japan. It is most regrettable that over 10,000 people killed or missing. This disaster in the north-eastern part of Japan is caused by seismic sea wave which is Tsunami. Tokyo and Yokohama area shook badly during the earthquake, fortunately west from Tokyo and Yokohama area are away from the south end of the epicenter and received almost no effects from Tsunami. Another concern is radiation leak from a reactor which is deadly damaged by the Tsunami. We are doing as much as we can and I am sure we will recover soon.
