Tug boats from Naval Base Guam responded quickly to the situation and safely moored both submarines.
USS Frank Cable (AS 40) moored at Alpha wharf and USS Oklahoma City (SSN 723) remained safely moored throughout the tsunami event.
At 7:45 pm, PNC News received several reports from witnesses at the Hagatna Marina who said they saw a sudden drop in the water level there of about 2 feet.
In all, National Weather Service Science Office Roger Edison reported a series of six surges, or waves, swept past the island Friday night. Edison said the waves arrived 30 to 40 minutes a part. The highest 3.5 feet.
National Weather Service Warning Coordination Meteorologist Chip Guard said the Warning was extended because the intensity of the first few waves did not decrease, as expected. Eventually they did and the ALL CLEAR was eventually sounded at anout 10:40 pm Friday night.
