A huge freak wave smashed down a door at a US Army barracks as the site was evacuated on Saturday night.
Furniture was sent flying when three to four-foot "weather-induced waves" hit Roi-Namur - an island in the northern part of the Kwajalein Atoll on the Marshall Islands.
The two sets of waves caused an evacuation of "non-mission personnel" before flooding struck two airports at Ailinglaplap Atoll - a ring-shaped island.
Army Public Affairs Officer Mike Brantley confirmed that one person suffered injuries to their lower body and received treatment.

In a statement, the US Army said: "We have accountability of all employees and evacuated all non-mission essential personnel to Kwajalein".
Other islands in the atoll also reported flooding which caused damage.
Airports in the area are said to be closed for a number of weeks.
The video, which has gone viral online, shows the moment the wave storms through the doors.

Footage shows the waves forcing its victims out of the way as people are spotted trying to grab onto anything that will stop them from floating away.
According to Marianas Variety, the first wave entered the base and the second one entered the dining hall, reaching a height of five feet.
The Army said: "US Army Garrison-Kwajalein Atoll and mission partners have established an Emergency Operations Cell to oversee and coordinate all recovery efforts."

A small island just three miles of Rio-Namur was unaffected by the wave blast and the overall flooding, David Paul, a Kwajalein Member of Parliament said.
An investigation by the Army found "how water inundation washed over" Rio-Namur, and flooded "at least one-third of it".
Roi-Namur hosts some of the US Army's most advanced space tracking equipment which is part of the Ronald Reagan Ballistic Missile Test Site.
