HVO Provides Eruption Update

Hawaiian Volcano Observatory on Wednesday morning reports that eruptive activity and ground cracking continues in the area of Leilani Estates and Lanipuna Gardens subdivision.

The middle portion of the fissure system continues to produce the most robust eruptive activity in the Lower East Rift Zone.

HVO officials say the most active fissures have been 22,19, 6, 5, and 23.

A faint glow was seen from Fissure 9, but no flows, and methane was observed burning in road cracks overnight.

In addition, the ocean entry remains active and is producing occasional small explosions.

HVO reports that observers noted the height of the perched lava pond/channel had reached 11 meters/36 feet above the ground level.

Volcanic gas emissions remain very high from these fissure eruptions.

HVO reports that magma continues to be supplied to the lower East Rift Zone.

Elevated earthquake activity continues, but earthquake locations have not moved farther downrift in the past couple of days, and there were only a few earthquakes located on Tuesday in the rift zone.

Small ash emissions from the Overlook crater occurred frequently throughout the night. Moderate trade winds were blowing to the southwest and ashfall may be noticed in downwind locations.

Earthquakes in the summit area continue at a moderate rate, as does deflation of the summit region.

HVO says that additional explosive events that could produce minor amounts of ashfall downwind are possible at any time. Volcanic gas emissions at the summit remain high.
