Guam - The U.S. Coast Guard Sector Guam crew worked through Friday and into Saturday morning to close, assess and reopen the ports of Guam, Saipan, Tinian and Rota after a major marine seismic event passed through the area Friday night. Crews had verified the waterways were safe for use and had reopened them by Saturday morning.
Damage assessments were conducted inside Apra Harbor on Saturday after two U.S. Navy submarines were detached from their mooring lines overnight. The tsunami caused minor fluctuations in sea levels in Guam and the CNMI just hours after a major earthquake hit the coast of Japan. Upon notification, the Coast Guard evacuated all personnel to high ground and sortied all three Coast Guard cutters.
The cutters have since returned to port Saturday morning. The public is asked to use precaution when boating.
