Tsunami waves from Tonga arrive in California (VIDEOS)

A massive underwater volcanic eruption in the South Pacific caused flooding in the US

A tsunami warning was put into effect for the US West Coast, Alaska, and Hawaii on Saturday, after a volcano erupted in the South Pacific near the island of Tonga. Videos of the ensuant flooding have been posted on social media.

“A tsunami is occurring,” the US National Weather Service announced, after tidal waves hit Tonga. 

Officials in California told those near coastal areas to move to higher ground, although they said the waves were not expected to reach more than two feet. Residents were warned that “pulses of surging water” could be just as dangerous as high waves, however.

Although there was none of the kind of major damage in the US that tsunamis usually create, footage posted online showed flooding in Santa Cruz and Sacramento, and the effect on beachside businesses.

In Hawaii, the waves reportedly carried boats onto docking areas, but no significant damage has otherwise been reported, with flooding being the key concern.

The eruption in Tonga led to numerous other nations issuing warnings over the weekend, including Japan, which suffered a devastating tsunami in 2011.
