U.S. Army Kwajalein Atoll is issuing a Tsunami Bulletin for July 30th, 2025, from 5:00pm till 6:00pm
A Tsunami Bulletin has been issued from the National Weather Station due to an 8.0 Magnitude Earthquake off the coast of Kamchatka Russia.
Tsunami waves reaching 0.3 to 1 meter above the tidal level are possible for some coastal areas of the Marshall Islands.
This would put Kwajalein Atoll at a potential Max of 6.5 feet above sea level.
Tsunamis: Kwajalein has a low risk for devastating effects from tsunamis. For a tsunami to produce devastating inundation and damage along coastlines, the sea floor must gradually rise up to the shoreline. This forces the tsunami to slow down and build in height, producing a high amplitude wave that can wash inland and cause significant damage. In contrast, Kwajalein Atoll, along with the other atolls of the Marshall Islands, has an extremely steep drop-off from the reef front into deep ocean waters. This prevents a tsunami from building up and allows them to predominantly pass with little noticeable effect.
Personal watercraft owners should check their watercraft mooring lines accordingly.
Small watercraft should restrict operations until after advisory.
