The Pacific nation of Tonga gave a tsunami warning Saturday after an undersea well of lava erupted.

Video presented via web-based media showed enormous waves washing aground in coastal regions.

The Tonga Meteorological Services said a wave cautioning had been placed in power for all of Tonga.

The eruption Saturday was the most recent in a progression of fabulous ejections from the Hunga Tonga Hunga Ha’apai volcano.
