Fissure 8 was active throughout Tuesday and into Wednesday morning sending fountains of lava at a sustained height of 200 feet with multiple secondary fountains that reached 60-feet.
This increased activity continued feeding a lava flow that moved towards Highway 132 at the rate of approximately 600 yards/hour. The flow moved north of Highway 132 in the vicinity of Noni Farms and Halekamahina roads, advancing along the steepest descent path that could take the flow to the Four Corners area.
Adding on to yesterday’s eruption, flow from fissure 18 increased further moving downslope toward Highway 137 at rates of less than 100 yards per hour. Overnight, sporadic bursts of activity were also observed from Fissures 7 and 15.
Pele's hair and other lightweight volcanic glass from high fountaining of Fissure 8 are falling to the west of the fissure and continue 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.
On the other hand, Kīlauea Volcano Summit saw relatively few activities on Tuesday and into Wednesday. Ash continued to erupt intermittently from the vent within Halemaʻumaʻu crater, but vertically high ash plumes were not recorded.
USGS warns that explosive events that could produce minor amounts of ash fall downwind are possible at any time. 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.
