Eruptions continue at Kilauea Volcano’s summit and East Rift Zone. The lava flow to the southeast of Pu’u ‘O’o continues to advance and does not pose a threat to nearby communities. The lava lake at Halema’uma’u Crater continues to circulate and spatter, and the lake level lowered several meters (yards) during the past day. Low rates of seismicity are observed across the volcano.
Tiltmeters at the summit continued to record a deflationary trend during the past 24 hours, and the level of the summit lava lake at Halema’uma’u lowered by about 6 m (20 ft). The lava level is about 40 m (131 ft) below the Halema’uma’u Crater floor this morning, a drop of at least 15 m (49 ft) since June 28. 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 3,400 to 6,000 metric tons/day.
Pu’u ‘O’o Observations:
HVO webcams show several incandescent vents on the floor of Pu’u ‘O’o crater, as usual. There are no significant changes in seismic activity at Pu’u ‘O’o. A tiltmeter on the north flank of Pu’u ‘O’o has recorded very little change during the past few days, and suggests that Pu’u ‘O’o has not yet responded to the deflationary trend at the summit. Sulfur dioxide emission rate from all East Rift Zone vents when last measured on June 27 was about 320 metric tons/day.
Lava Flow Observations:
The active lava flow southeast of Pu’u ‘O’o continued to advance during the past day. Geologists reported yesterday afternoon that the flow reached the base of the pali along the western boundary of the abandoned Royal Gardens subdivision. The flow advanced about 0.6 km (0.4 miles) between Tuesday and Wednesday afternoon, making the flow about 7.5 km (4.7 miles) long and about 3.5 km (2.2 miles) from the ocean. Bright incandescence is visible in the overnight webcam views of the active lava flow field, marking lava tube skylights and activity near the flow front.
Smoke from burning trees and open channels of lava could easily be seen Tuesday from Kalapana as the lava flow from Kilauea’s Pu‘u ‘O‘o vent traveled down Pulama pali.
Using a satellite image taken Monday, Hawaiian Volcano Observatory said the flow was more than 3.9 miles long and was advancing down the western boundary of the abandoned Royal Gardens subdivision at about 0.2 miles per day.
