Kilauea Volcano Lower East Rift Zone

Vigorous eruption of lava continues from the lower East Rift Zone (LERZ) fissure system in the area of Leilani Estates and Lanipuna Gardens.

Fissure 8 maintained high fountains through Wednesday with sustained heights exceeding 200 feet and the presence of multiple secondary fountains that reached to 60 feet. This fountaining continued to feed a lava flow that moved downslope along Highway 132. Advance rates were less than 100 yards/hour for the three lobes of the flow. The flow moved north of Highway 132 in the vicinity of Noni Farms and Halekamahina roads, from which the two easternmost lobes advanced in a more east northeasterly direction while the westernmost lobe advanced in a northeasterly direction.

The Fissure 18 flow also remained active, moving downslope toward Highway 137 at rates of much less than 100 yards per hour. During the day, sporadic bursts of activity were also observed from Fissures 22, 6, and 13.

Pele's hair and and other lightweight volcanic glass from high fountaining of Fissure 8 are falling to the west of the fissure and accumulating on the ground within Leilani Estates. Winds my waft lighter particles to greater distances. Residents are urged to minimize exposure to these volcanic particles, which can cause skin and eye irritation similar to volcanic ash.

HVO field crews are on site tracking the fountains, lava flows, and spattering from multiple fissures as conditions allow and reporting information to Hawaii County Civil Defense. Crews are also checking on the status of ground cracks on Highway 130.

Volcanic gas emissions remain very high from the fissure eruptions. Wind conditions for Wednesday, May 30, are forecast to result in widespread vog over the Island of Hawaii.

Magma continues to be supplied to the lower East Rift Zone. Earthquake locations have not moved farther downrift in the past few days and the number of located earthquakes remains low.

Additional ground cracking and outbreaks of lava in the area of the active fissures are possible. Residents downslope of the region of fissures should heed all Hawaii County Civil Defense messages and warnings.

USGS/HVO continues to monitor the lower East Rift Zone activity 24/7 in coordination with Hawaii County Civil Defense.

Kilauea Volcano Summit

Ash continued to erupt intermittently from the vent within Halema?uma?u crater, at Kilauea's summit. The National Weather Service observed an ash column rising to 12,000 ft at around 11 am this morning but visibility was very poor on the ground and ground observers could confirm the event. Additional explosive events that could produce minor amounts of ash fall downwind are possible at any time. Earthquake activity is elevated at the summit, with a few felt events reported overnight. Volcanic gas emissions at the summit remain high and will combine with wind conditions to produce widespread vog across the Island of Hawaii on Wednesday.

For forecasts of where ash would fall under forecast wind conditions, please consult the Ash3D model output here: Hawaiian Volcano Observatory

Information on volcanic ash hazards and how to prepare for ash fall maybe found at Public Information | IVHHN (health impacts) OR Volcanic Ash Impacts & Mitigation - Volcanic Ash Impacts & Mitigation (other impacts).
