A tsunami advisory has been issued for the West Coast of the United States and Alaska

The news follows an underwater volcanic eruption near Tonga.

The National Tsunami Warning Center has issued a tsunami advisory in effect for the entire West Coast and Alaska following an underwater volcanic eruption near Tonga.

Almost all coastal areas of California, Oregon, Washington State, Southeast Alaska, Southern Alaska, the Alaska Peninsula, and the Aleutian Islands are l subject of a tsunami advisory. British Columbia is also under notice.

A tsunami warning means that a tsunami could produce strong currents or waves near the shore. However, a tsunami advisory does not indicate a major tsunami where water is actively entering coastal communities. Under these circumstances, the tsunami is only dangerous to those in the water or on the immediate beach, such as swimmers and boaters.
