Kilauea, Hawai : The lake surface height fluctuated .

Activity Summary:
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 6 km (4 mi) northeast of Pu’u ‘O’o . These flows currently pose no threat to nearby communities.

Summit Observations:
The lava lake remains active within the Halema’uma’u Overlook crater. The lake surface height fluctuated slightly over the past day during spattering and non-spattering intervals but remains approximately 35 m (121 ft) below the crater rim this morning. No significant tilt was observed at summit tiltmeters over the past day. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. The summit sulfur dioxide emission rate averaged 5,300 metric tons/day on January 21 and 22.

Pu’u ‘O’o Observations:
Webcam images over the past 24 hours show persistent glow at long-term sources within the crater and high on the northeast flank of the cone. Seismic activity remains low at Pu’u ‘O’o. A tiltmeter on the cone has recorded steady, gentle deflationary tilt change over the past several days. The sulfur dioxide emission rate from all East Rift Zone vents was about 220 metric tons/day when it was last measured on January 21.


A closer view of Pu’u ‘O’o, just above the center point of the photograph. View is towards the southwest. In the foreground, the circular lava pond that was active in July 2014 is visible. The lava tube feeding the active flows on the June 27th lava flow is evident by the line of white fume sources extending off the right side of the photograph.

June 27th Lava Flow Observations:
Webcam images show continued surface flow activity on the June 27th flow field, with smoke plumes where lava is igniting forest. Yesterday’s HVO field crew verified that active flows are within about 6 km (4 mi) northeast of Pu’u ‘O’o and are not currently threatening any nearby communities.
