Tsunami impacts hit West Coast after volcano eruption in Pacific; stay away from beaches, officials warn Updated 6:04 pm EST Jan. 15, 2022

West Coast authorities pleaded with residents to stay out of the Pacific Ocean and away from beaches on Saturday as the impacts of a tsunami caused by a volcanic eruption in the South Pacific began hitting the coast.

While forecasted waves were generally less than 3 feet, tsunami impacts create unpredictable currents and tides that could endanger swimmers and boaters. The waves are expected to arrive in pulses throughout the day.

"There are extremely powerful currents associated with the surges and if you are pulled into the water it will overpower you," the Marin County, Calif. Sheriff tweeted, sharing a photo of a damaged dock in the area.
