Bubble burst explosion, Kīlauea Volcano, Hawai‘i...

Detailed Description

Bubble-burst explosion caused by subsidence of an active lava delta, which allows seawater to gain access to part of the lava tube system within the delta. Bubble bursts are characterized by sporadic bursts of molten, dome-shaped lava sheets emanating from a circular rupture in the roof of a tube a few meters inland from the shoreline. Individual bubbles can reach diameters of 10 m in less than 2 seconds before they burst.
