Kilauea , Hawai : The lava lake within the Halema’uma’u Overlook crater continues to be active.

Activity Summary:
Kilauea Volcano continues to erupt at its summit and from its East Rift Zone. The summit is currently experiencing deflationary tilt consistent with the beginning of a DI event. Overall seismicity and deformation rates are within normal range. Scattered surface flows persist in the ‘June 27th’ flow field; all within 6 km (4 mi) of Pu’u ‘O’o.

Summit Observations:
The lava lake within the Halema’uma’u Overlook crater continues to be active. For most of the past 24 hours it had a height of about 29 m (95 ft) below the rim of the Overlook crater. At 2:00 AM HST, the level began to drop and as of 8:30 AM HST is at 33 m (108 ft) below the crater rim. The change in lava lake level coincided with a change from minor inflationary to deflationary tilt, consistent with the beginning of a summit DI event (see link below for definition). Rates of seismicity remain low with periods of tremor associated with spattering within the Overlook vent. 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:
Thermal webcam images show no significant changes in Pu’u ‘O’o crater; persistent glow continues at long-term sources. Only minor inflationary tilt was recorded on a nearby tiltmeter and the seismicity rate remains at background level. The sulfur dioxide emission rate from all East Rift Zone vents was about 345 metric tons/day when it was last measured on February 2, 2016.

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