Several elements of the federal government are responding to the Japanese earthquake by deploying personnel and observing the response from Washington. Here’s a department-by-department breakdown of agency activities as of Monday afternoon.


All U.S. government personnel in Japan are accounted for, according to the State Department. U.S. citizens in Japan in need of emergency assistance, or people seeking information on the whereabouts of friends, family or colleagues, should send an e-mail to

The federal agency chiefly responsible for assisting foreign governments with disaster response has deployed urban search-and-rescue teams from Fairfax, Va., and Los Angeles to Japan. The rescue teams, which also deployed to Haiti after last year’s quake, include about 150 personnel and 12 dogs trained to find live victims.

USAID’s Disaster Assistance Response Team is also in Japan coordinating the U.S. government’s response.

The Japanese government has formally requested U.S. assistance in responding to nuclear plant cooling issues, and the NRC is considering ways to respond, the agency said Monday.

Two of the agency’s boiling-water reactor experts deployed with the USAID response team to provide technical assistance to Japanese officials. Agency officials are also monitoring developments from its Rockville headquarters.

The NRC is led by a five-member commission and crafts the nation's nuclear policies and regulations. It has said that the steps taken thus far by Japanese officials are in line with what they would have done if U.S. nuclear plants were similarly affected.

It will not comment on the specifics of the Japanese response, however. “This is an ongoing crisis for the Japanese who have primary responsibility,” the agency said in a statement.


The U.S. military has about 50,000 personnel stationed in Japan, many of whom are already providing disaster assistance.

The Navy has P-3 Orion aircraft flying to help survey the wreckage and spot potential survivors.

The U.S.S. Ronald Reagan Carrier Strike Group is operating off the east coast of the island of Honshu, with more ships on the way, according to the Pentagon.

The U.S.S. Tortuga, which contains MH-53 heavy-lift helicopters, is also headed to the east coast of Japan to provide assistance. It is carrying 90 Japanese Self-Defense Force vehicles and personnel.

Other U.S. ships are expected to arrive in the area by Thursday, the Defense Department said.

No U.S. bases are in the danger zone for radioactivity, and there are no plans to evacuate any U.S. personnel or their families, according to Pentagon spokesman Col. Dave Lapan.
