Low-Level Eruptive Activity Continues Along Fissure System

Low-level eruption of lava continues from multiple points along the northeast end of the active fissure system, according to Hawaiian Volcanoes Observatory at 10:40 a.m.

Spattering continues from Fissure 17 but the lava flow erupted from the fissure has not advanced significantly over the past day.

HVO field crews are on site tracking the lava flow and spattering from multiple fissures as conditions allow and reporting information to Hawaii County Civil Defense.

Volcanic gas emissions remain elevated throughout the area downwind of the vents. Weak winds today means that other areas of Hawaii Island may experience varying levels of vog.

This eruption is still evolving and additional outbreaks of lava are possible. Ground deformation continues and seismicity remains elevated in the area.

Future outbreaks could occur both uprift (southwest) and downrift (northeast) of the existing fissures, or, existing fissures can be reactivated. Communities downslope of these fissures could be at risk from lava inundation. Activity can change rapidly.

Just after 4 a.m. this morning, an explosion or series of explosions from the Overlook vent within Halemaumau crater at Kilauea Volcano’s summit produced a volcanic cloud that reached as high as 30,000 ft asl based on NWS radar information. The cloud drifted generally northeast and traces of ash fell with rain in the Volcano Golf Course, Volcano Village, and other areas immediately around the Kilauea summit.

At this time, based on HVO web cameras, a robust plume of gas, steam, and some ash is billowing out of the Overlook vent and drifting generally southwest.

At any time, activity may again become more explosive, increasing the intensity of ash production and producing ballistic projectiles very near the vent. Communities downwind should be prepared for ashfall as long as this activity continues.

Seismicity and deformation continue at the Kilauea summit. Deflation is ongoing. Additional earthquakes in the Kilauea summit area are expected as long as the summit continues to deflate.
