USGS June 11th and 12th Videos -Lava Flow to the Ocean in Hawaii


First published at 10:26 UTC on June 13th, 2018.

Aerial views of the ocean entry on Kilauea Volcano's lower East Rift Zone on June 12, 2018, around 6:30 a.m. HST, show multiple small lava streams spilling into the ocean along the southern portion of the lava delta in Kapoho Bay. The interaction of molten lava and ocean water creates "laze," a corrosive mixture of seawater steam, hydrochloric acid, and fine volcanic glass particles that can irritate the skin, eyes, and lungs. The helicopter overflight traveled from north to south along the coast

The interaction of molten lava flowing into cool seawater causes pulsating "littoral explosions" that throw spatter (fragments of molten lava) and pieces of solidified glassy lava (black sand, Pele's hair, limu o Pele) high into the air. In this aerial view of the Kapoho ocean entry, these dark-colored lava particles are blasted skyward through billowing white clouds of seawater steam (laze). Ocean entry littoral explosions can create hazardous conditions both on land and at sea.

The three closely spaced lava fountains at Fissure 8 continue to feed a channelized flow trending north and then east to the ocean entry at Kapoho.

Three closely spaced lava fountains at fissure 8 continue to feed a channelized flow trending north and then east to the ocean entry at Kapoho Bay. This video is from an HVO helicopter overflight of the braided lava channel this morning around 6:30 a.m. HST. Minor overflows of the channel levees have occurred at several places along the channel, but have been short-lived and do not pose an immediate threat to areas not previously covered by lava.
