Kilauea , Hawai : Eruptive activity continues at Kilauea Volcano’s summit

Activity Summary:
Eruptive activity continues at Kilauea Volcano’s summit and East Rift Zone. Seismicity and deformation rates throughout the volcano remain within 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. Summit tiltmeters recorded deflationary tilt starting this morning at about 2 am. The level of the lava lake this morning is similar to that measured yesterday, at about 34 m (110 feet) below the crater rim. Seismic tremor has been weakly variable, reflecting small changes in the vigor of spattering on the lava lake. 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. Several very small lava flows erupted yesterday afternoon on the crater floor, but these were very brief. Seismic activity remains low at Pu’u ‘O’o. A tiltmeter on the cone recorded slight deflationary tilt starting yesterday at noon, but there has been an overall inflationary trend since early January. 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 and satellite images show continued surface flow activity on the June 27th flow field. Smoke plumes are visible in the webcam images where lava is igniting forest. The most distal active lava is within 6 km (4 mi) northeast of Pu’u ‘O’o and is not currently threatening any nearby communities.
