Large swells from the north-northeast with heights up to 5 meters (16 feet) combined with unusually high tides inundated much of the Republic of the Marshall Islands on March 2, 2014.

Waves wash over a road on Roi-Namur Island, Kwajalein Atoll in the Republic of the Marshall Islands, during a particularly high tidal event. USGS is studying how slightly reduced rainfall combined with sea-level rise affect freshwater sources on low-lying Pacific coral islands.

Some areas that would be inundated (in red) during the SAFRR tsunami scenario. Top, in Oakland and Alameda, in the eastern San Francisco Bay area, large parts of the Oakland Airport would be flooded.

Maximum current speeds for the Port of Los Angeles (POLA) and the Port of Long Beach (POLB) generated during the SAFRR tsunami scenario. The ports are protected by a breakwater, but during the tsunami there would be dangerously fast currents around the port entrances in the wall, locally referred to as “Angels Gate” (at POLA) and “Queens Gate” (at POLB).

Hundreds of catsharks, or chainlink dogfish, rest on one of the "Billy Mitchell" Fleet shipwrecks. The shipwreck has also been occupied by colonies of anemones, starfish, and hydroids.
