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.
The lava lake remains active within the Halema’uma’u Overlook crater. The lake height fluctuated slightly over the past day due to changes in spattering, remaining at approximately 39 m (128 ft) below the crater rim this morning. No significant change in tilt was observed at summit tiltmeters over the past day. Seismicity is within normal, background rates with tremor fluctuations associated with lava lake spattering. For the period December 30, 2015 – January 5, 2016, the summit sulfur dioxide emission rate averaged 6,200 metric tons/day.
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. The HVO field crew working at the cone on 1/19 reported continued activity at established vents within the crater. Seismic activity remains low at Pu’u ‘O’o. A tiltmeter on the cone recorded no significant tilt change over the past day. The sulfur dioxide emission rate from all East Rift Zone vents was about 270 metric tons/day when it was last measured on January 4.
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.

Viewing conditions into Pu’u ‘O’o Crater were exceptional today, providing clear views of the crater floor. This view is towards the northwest. The inner, deeper crater formed in mid-2014 following the opening of the June 27th vent, and occasional small flows on the crater floor are evident by their dark color. The smaller, circular pit in the west portion of the crater has contained a small, active lava pond in recent months. Very little of the original cone, formed in the early part of the Pu’u ‘O’o eruption in the mid-1980s, remains visible on the surface. The tan colored area in the foreground, and the brown sections of the crater rim in the upper part of the photograph, are the original portions of the cone and consist of cinder and scoria.
