I heard a spokesman from AFLAC being interviewed, that company insures 1 out of 4 Japanese. They'll take a hit but I would imagine they've covered the risk with reinsurance agreements.
Also saw that this quake did not occur where the 'big one' was predicted to occur. Meaning, the 'big one' in Japan is still possible.
This one was certainly big enough,
it moved the coast of Japan by 8 feet and moved the Earth's axis by 4 inches! The physics required to do that is just staggering.
