Dallol

Cratere esplosivo · Ethiopia · 48 m (sottomarino)

Colorful hot brine pools up to about a meter in diameter with terraces at hot springs at Dallol. Numerous phreatic explosion craters dot the Salt Plain NNE of the Erta Ale Range in one of the lowest areas of the Danakil depression. These craters mark Earth's lowest known subaerial volcanic vents. The most recent of these craters, Dallol, lies 48 m below sea level and was formed during an eruption in 1926.

Sintesi geologica

Numerous phreatic explosion craters are present across the Salt Plain NNE of the Erta Ale Range in one of the lowest areas of the desolate Danakil depression. The most recent of these craters, Dallol, lies 48 m below sea level and was formed during an eruption in 1926. Colorful hot brine springs are found in the Dallol area. Another phreatic explosion was observed in January 2011.

Sintesi da Wikipedia

Riassunto in inglese

Dallol is a unique, terrestrial hydrothermal system around a cinder cone volcano in the Danakil Depression, northeast of the Erta Ale Range in Ethiopia. It is known for its unearthly colors and mineral patterns, and the very acidic fluids, commonly noted as some of the most acidic on Earth, that discharge from its hydrothermal springs.
