Two Southern California ports on March 11 took precautionary measures in response to the tsunami advisory issued after a major earthquake struck Japan.

The Port of Los Angeles said it temporarily suspended transfer of hazardous materials and bunkering fuel operations as a precaution, but that normal cargo operations were not interrupted.

The Port of Long Beach reported minor interruption in operations, and port officials monitored the situation in cooperation with the U.S. Coast Guard and other government agencies. The port cited a 2007 report that showed it faced a minimal risk of inundation by tsunami.

The 8.9 magnitude earthquake off the eastern coast of Japan triggered a tsunami warning for Southern California.

UPS said the tsunami was affecting UPS service in areas of Hawaii and northern California. FedEx suspended all pickups and deliveries in East Japan.
