Much of the West Coast is under a tsunami advisory on Saturday.

This includes the states of California, Oregon, Washington, and Alaska.

Residents in Los Angeles woke up to a tsunami notification on their phone.

They warned that the conditions are likely to cause strong rip currents.

The National Weather Service told people to stay away from beaches and water.

The tsunami alert was caused by an underwater volcanic eruption near Tonga.

The Hunga-Tonga-Hunga-Ha’apai volcano erupted on Friday.

It sent ash clouds and gas steam over 12.4 miles into the air.

The volcano erupted later on Saturday, causing tsunami warnings.
