The U.S. Northern Command has set up two reception centers on the West Coast to arrange temporary lodging, food, pet care and other accommodations for U.S. military families who are returning from Japan after the earthquake, tsunami and nuclear reactor crisis.

Northern Command, based at Peterson Air Force Base, Colo., said Tuesday the centers had been set up at Seattle-Tacoma Airport in Washington and Travis Air Force Base in California.

Officials said another reception center could be opened if necessary.

Northern Command is responsible for the military defense of U.S. soil and supporting civilian agencies in natural or human-caused disasters.
