Eruptive activity continues at Kilauea Volcano’s summit and East Rift Zone. Seismicity and deformation rates throughout the volcano remain at background levels. Scattered lava flow activity continues on the June 27th lava flow field within about 5.7 km (3.5 mi) northeast of Pu’u ‘O’o . These flows currently pose no threat to nearby communities.
The lava lake within the Halema’uma’u Overlook crater remains active and was measured at 29.5 m (97 ft) below the crater rim on Friday, April 29, 2016. Tiltmeters at Kilauea’s summit have recorded deflationary tilt. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. The summit sulfur dioxide emission rate averaged 4,900 metric tons/day on April 25.
Pu’u ‘O’o Observations:
Webcam images over the past 24 hours show persistent glow at long-term sources within the crater and from skylights in the lava tube on the northeast flank of the cone. Small pahoehoe ooze outs continue on the crater floor from the eastern vent within the crater. Seismic activity remains low at Pu’u ‘O’o. A tiltmeter on the cone recorded no significant change since yesterday when we noted the tilt was flat. The sulfur dioxide emission rate from all East Rift Zone vents was about 300 metric tons/day when last measured on April 20.
June 27th Lava Flow Observations:
Webcam images show continued surface flow activity on the June 27th flow field. The active flows are comprised of small breakouts scattered northeast of Pu’u ‘O’o, where they have been occurring for the past several months. This pattern is consistent with field observations on April 12, when the most distant breakouts were about 5.7 km (3.5 mi) northeast of Pu’u ‘O’o. The flows are not currently threatening any nearby communities.
