HAWAII VOLCANOES NATIONAL PARK – The lava ocean entry continues at Kamokuna inside the Hawaii Volcanoes National Park.

Mick Kalber recorded this video on October 5, over the lava flow aboard Paradise Helicopters.

Last week, scientists with the USGS Hawaiian Volcano Observatory noted that cracks running parallel to the coast have developed in the large, 12.9 acre eastern delta. HVO says this indicates that the delta is becoming increasingly unstable and could collapse further into the sea.

The National Park Service Eruption Crew staff reported a collapse of the eastern portion of the delta sometime between Sunday evening and Tuesday afternoon.

Hazardous delta collapses occur without warning and can trigger explosions of hot flying debris as seawater contacts newly exposed molten lava.

Kilauea volcano’s East Rift Zone eruption began in January 1983, and centers around the vent at Pu’u O’o. Over the decades there have been numerous changes in the ongoing eruption.

On May 24, the 61g lava flow began, breaking out on the east flank of Pu’u O’o, and eventually heading south, down the pali, and towards the sea.

The new ocean entry began early in the morning on July 26.
