Eruptions continue at Kilauea Volcano’s summit and East Rift Zone. Seismic activity and deformation rates throughout the volcano are within background levels. East rift zone webcams show a new fuming, incandescent, but otherwise inactive, spot on the east rim of Pu’u ‘O’o crater and persistent scattered activity on the June 27th lava flow field within 6 km northeast of Pu’u ‘O’o vent. Lava flow activity poses no threat to nearby communities.
The lava lake remains active and circulating within Halema’uma’u Overlook crater. Seismic tremor levels have been variable but within background values. Tiltmeters resumed recording weak deflationary tilt overnight and the lava lake surface fell several more meters. Summit sulfur dioxide emission rates averaged around 4,200 metric tons/day for the week ending December 1.
Pu’u ‘O’o Observations:
Webcam images still show the new incandescent, fuming source on the east rim of the crater mentioned in yesterday’s update (far right edge of PNcam view). Seismic activity remains low. Pu’u ‘O’o tiltmeters recorded slightly more than one microradian of deflationary ground tilt since noon on December 07. The sulfur dioxide emission rate from all East Rift Zone vents was about 280 metric tons/day when measurements were last measured on November 30, 2015.
June 27th Lava Flow Observations:
Webcam views confirm continued activity mostly within the Pu’u ‘O’o flow field with minor burning along the forest edge. Active flows persist within roughly 6 km (4 mi) of Pu’u ‘O’o and are not threatening any nearby communities.
