Kīlauea 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.
Fountaining at Fissure 8 continued unabated during the day, feeding a channelized lava flow to the northeast along Highway 132 that has crossed Highway 137 at the intersection of the two highways at 9:30 AM this morning. The flow continued advancing into Kapoho Crater and Kapoho Beach Lots. At 10 AM, lava entered Green Lake within Kapoho Crater producing a large steam plume. By 1:30 PM the steam plume had ceased and by 3 pm, a Hawaii County Fire Department overflight reported that lava had filled the lake and apparently evaporated all the water. Other branches of the Fissure 8 lava flow were inactive.
The only other lava flow noted by the morning overflight was at Fissure 16, which was weakly active.
Pele's hair and other lightweight volcanic glass from high fountaining of Fissure 8 are falling downwind of the fissure and accumulating on the ground within Leilani Estates. Winds may 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.
The most recent map of lava flows can be found at https://volcanoes.usgs.gov/volcanoes/kilauea/multimedia_maps.html.
HVO field crews are on site tracking the fountains, lava flows, and spattering from multiple fissures as conditions allow and are reporting information to Hawaii County Civil Defense.
Volcanic gas emissions remain very high from the fissure eruptions. Trade wind conditions are bringing vog to the south and west sides of 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. Seismicity remains relatively low with numerous small magnitude earthquakes and low amplitude background tremor.
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.
Kīlauea Volcano Summit
Earthquake activity at the summit overnight was low. Ash emissions are low as revealed by webcam views this morning. Small explosive events could produce minor amounts of ash fall downwind at any time. Volcanic gas emissions at the summit remain high.
For forecasts of where ash would fall under forecast wind conditions, please consult the Ash3D model output here: https://volcanoes.usgs.gov/observatories/hvo/activity_2018.html
Information on volcanic ash hazards and how to prepare for ash fall maybe found at http://www.ivhhn.org/information#ash (health impacts) OR https://volcanoes.usgs.gov/volcanic_ash/ (other impacts).
