At 2:46 p.m. Tokyo time, Japan was hit with what early news reports are calling the most powerful earthquake in a century. An 8.9 magnitude quake occurring about 230 miles northeast of Tokyo set off muddy tsunami waves washing across land (videos below). Houses floated "like rafts" from the tsunami waves, thousands of people were evacuated from their homes, train and air transportation were severely disrupted, and "major damage across wide areas," was announced by Japanese Prime Minister Naoto Kan.
As of now, hundreds are estimated to be believed dead according to Japan's Kyodo News agency, the Associated Press and the Los Angeles Times, and tsunami alerts were issued for "dozens of countries" including Hawaii, Alaska and the West coast of California north of Santa Barbara and up to Oregon. The White House has issued a statement (via AP) saying that Obama "has told the Federal Emergency Management Agency to be ready to assist Hawaii and any other U.S. states and territories that might be affected. He said he's ready to support the Japanese people 'in this time of great trial.'"
Of the economic damage already done to Japan, the Wall Street Journal reported that yen and Tokyo stocks fell, while government bonds gained. "The natural disaster could derail the country's nascent economic recovery and increase Japan's already massive public debt, which is 200% of gross domestic product," the Journal noted.
