A submarine volcano located near Tonga in the Southern Pacific region called Hunga Tonga Hunga Ha’apai volcano erupted on Saturday afternoon local time in Tonga. This last impressive explosion comes after a series of strong eruptions happening since December 2021. The volcano is located about 18.6 miles southeast of Tonga's Fonuafo'ou island.

There was a large explosion that began on January 14, which sent ash about 12 miles up in the air, prompting tsunami warnings for the Tonga residents.

The eruption of January 15 produced a mushroom-like explosion that launched ash about 11 miles up in the air, this time there are also advisories for airlines. There was a magnitude 4.0 earthquake registered in Tonga shortly after the eruption.

Tsunami warnings are in effect for the entire U.S. West coast.

Tsunami waves of between 3 and 4 feet stroke, Nuku’alofa, the capital of Tonga, as the ash clouds were also seen obscuring the sun. Pacific islands like Fiji, and American Samoa, have also registered small tsunami waves. The Vanuatu Islands recorded larger tsunami waves between 3 and 8 feet.

In Hawaii, tsunami waves have pushed boats out of the water and onto docks.

The entire west coast of the United States, from Alaska through Southern California is also under a tsunami warning as tsunami waves arrive in the area.
