New Lava Fissures Possible as Residents Near Kilauea Warned to be on Alert

Eruption of lava from Kilauea continues in the area of Leilani Estates and Lanipuna Gardens subdivision on the island of Hawaii.

The middle portion of the fissure system (centered on Pohoiki Rd.) continues to produce the most robust eruptive activity in the Lower East Rift Zone. Field crews observed that fissure areas 2, 7, 8 and 3, 14, 21 (between Luana and Kaupili St. in Leilani Estates) reactivated and are spattering. Intermittent signals recorded on sensors closest to the two ocean entries suggest they remain active.

Volcanic gas emissions remain very high from the fissure eruptions.

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.

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. The number of located earthquakes remains low.

USGS/HVO continues to monitor the lower East Rift Zone activity 24/7 in coordination with Hawaii County Civil Defense. Geologists are onsite to track fissure activity and the advance of lava flows.

Ash emissions from the Kilauea summit reached 6,000 feet during the most energetic explosions above sea level as observed in the National Weather Service radar, but dispersed quickly.

Earthquakes in the summit area continue at a moderate rate, as does deflation of the summit region. The earthquakes and ash explosions are occurring as the summit area subsides and adjusts to the withdrawal of magma from the summit.

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