Kilauea , Hawai : A moderate-size of the crater wall collapse into the summit lava lake.

Activity Summary:
Kilauea Volcano continues to erupt at its summit and from its East Rift Zone. Scattered surface flows remain active on the ‘June 27th’ flow field within 6.0 km (4 mi) of Pu’u ‘O’o and do not currently threaten any nearby communities. Seismicity and deformation are within normal levels throughout the volcano.

Summit Observations:
Kilauea Volcano continues to host a lava lake at its summit; with a current height of approximately 50 m (165 ft) below the rim of the Overlook crater. Tiltmeters continued to record slightly inflationary tilt, though two apparent excursions at one tiltmeter early this morning were determined to be due to instrumental noise. Rates of seismicity continue to be normal, with periods of tremor associated with spattering within the Overlook vent. A moderate-size collapse of the crater wall into the summit lava lake early yesterday was visible on summit webcams and sent a sprinkling of ash to the caldera rim. When last measured by vehicle in late January, the summit sulfur dioxide emission rate averaged 5,300 metric tons/day.

Pu’u ‘O’o Observations:
No significant change in the incandescent vents is visible on thermal webcam images of Pu’u ‘O’o crater. Minor deflationary tilt continued through the past day and seismic activity was at background rates. The sulfur dioxide emission rate from all East Rift Zone vents was about 300 metric tons/day when it was last measured on February 16, 2016.

June 27th Lava Flow Observations:
Webcams continue to show scattered surface flow activity on the ‘June 27th’ flow field. All active flows are within 6 km (4 mi) northeast of Pu’u ‘O’o and do not currently threaten any nearby communities.
