Eruptive activity continues at Kilauea Volcano’s summit and East Rift Zone. The two new lava flows from Pu’u ‘O’o are still active but have not advanced significantly overnight. At the summit, deflationary tilt continues and the lava lake level has changed little. Scattered lava flow activity continued on the June 27th lava flow field within about 5 km (3 mi) northeast of Pu’u ‘O’o. None of the Pu’u ‘O’o flows currently pose a threat to nearby communities.
Deflationary tilt continued at the summit over the past day. This morning the lava lake level was measured at 39.5 m (130 ft) below the floor of Halema’uma’u crater. Tremor fluctuations associated with lava lake spattering continue. Sulfur dioxide emissions from the summit vent ranged from 4,100 to 7,000 t/d during the past week. Data from GPS networks and interferometric satellite radar (InSAR) show continued long-term inflation of the summit and upper Southwest Rift Zone magma reservoirs.
Pu’u ‘O’o Observations:
The two new lava flows from Pu’u ‘O’o, which began on May 24, are still active but have not advanced significantly over the past day. One lobe extends about 1.2 km (4,100 ft) to the northwest and another extends about 1.2 km (4,100 ft) to the southeast. Webcam views of both breakouts overnight show continued surface activity feeding these flows. Neither lava flow has extended beyond the existing Pu’u ‘O’o flow field. For recent photographs and maps of these two new active flows, see web links below. Deflationary tilt at Pu’u ‘O’o continued over the past day. Persistent glow from spatter cones within the crater continues; slight subsidence of the crater floor was observed overnight. The sulfur dioxide emission rate from all East Rift Zone vents was about 460 metric tons/day when last measured on May 24.
June 27th Lava Flow Observations:
In addition to the new lava flows on the flanks of Pu’u ‘O’o, surface flow activity on the June 27th flow field continues, with small breakouts scattered northeast of Pu’u ‘O’o where they have been occurring for the past several months. Recent satellite images indicate that the active breakouts are within about 5 km (3 mi) northeast of Pu’u ‘O’o. The flows are not currently threatening any nearby communities.
