Eruptions continue at Kilauea Volcano’s summit and East Rift Zone. The lava flow to the southeast of Pu’u’O’o continues to spread and advance, still posing no threat to nearby communities. The lava lake at Halema’uma’u Crater continues to circulate and spatter, and the lake level has been relatively steady over the past day. Low rates of seismicity are observed across the volcano, and long-term deformation trends show continued inflation beneath the summit and uppermost Southwest Rift Zone.
Gentle inflationary tilt continues. The summit lava lake at Halema’uma’u continues to circulate and spatter. This morning, the lake surface is roughly 27 m (~90 ft) below the adjacent crater floor, and spattering in the lake was visible from HVO. Low rates of seismicity in the summit caldera region are noted, with minor fluctuations in seismic tremor related to variations in lava lake circulation and spattering. Sulfur dioxide emissions from the summit vent over the past week ranged from 3,500 to 7,000 metric tons/day.
HVO webcams show several incandescent vents on the floor of Pu’u’O’o crater, as usual. Tilt has been affected by rainfall over the past day. There are no significant changes in seismic activity at Pu’u’O’o. Sulfur dioxide emission rate from all East Rift Zone vents when last measured on June 22 was about 350 metric tons/day.
Lava Flow Observations:
The active lava flow southeast of Pu’u’O’o continues to advance and spread. A satellite image from Friday, June 24, showed that the flow was 5.2 km (3.2 miles) long, and a small area of the flow front had entered the northern portion of the abandoned Royal Gardens subdivision. During last week the flow front advanced at a rate of roughly 100 m per day (330 ft per day). Bright incandescence is visible in the overnight webcam views of the active lava flow field, marking lava tube skylights and scattered breakouts near the flow front.
This map shows recent changes to Kilauea’s active East Rift Zone lava flow field. The areas covered by the recent breakouts at Pu’u’O’o as of June 16 are shown in pink, while widening and advancement of the active flow as mapped on June 23 is shown in red. The area covered by the inactive June 27th flow is shown in orange. Pu’u’O’o lava flows erupted prior to June 27, 2014, are shown in gray.
