The Washington Post:

The powerful eruption of an undersea volcano near the Tonga islands in the Pacific Ocean sent tsunami waves around the world on Saturday, closing beaches, flooding marinas and activating emergency plans from Japan to California.

Experts say the Tongan volcano is capable of producing an explosion that massive roughly every 1,000 years, akin to a weapons-grade chemical explosion.
