Kilauea , Hawai : Kilauea Volcano continues to erupt at its summit and East Rift Zone.

Activity Summary:

Kilauea Volcano continues to erupt at its summit and East Rift Zone. At the summit, the lava lake within Halema’uma’u Overlook vent continues to circulate and spatter. A gas plume during the day and glow at night are visible. At the East Rift Zone eruption sites, webcams show persistent incandescent outgassing sites at Pu’u ‘O’o and active lava breakouts within an area reaching roughly 8 km (5 mi) northeast of Pu’u ‘O’o. Updates of the June 27 (2014) lava flow map via data from remote sensing sources show expansion of the flow field from a number of breakout locations. Seismic activity continues at low levels.

Summit Observations:

Lava lake circulation and spatter within the Overlook vent continue, with no significant changes at Kilauea summit evident in the daily tilt or seismic records. Lava lake level measured and posted Friday morning was 46.5 m (152 ft) below the rim of the Overlook vent. Very low levels of background seismicity continue, with the principal registration being persistent volcanic tremor and changes in tremor strength, rather than discrete seismic events. Available measurements of sulfur dioxide emission rates for the week ending July 7 ranged from 2,000 to 3,300 tonnes/day to 9,100 tonnes/day.

Pu’u ‘O’o Observations:

No significant changes are evident at Pu’u ‘O’o . Webcams show multiple incandescent outgassing vents persisting within the crater. Low levels of background seismic activity continue. The sulfur dioxide emission rate from all East Rift Zone vents was roughly 700 tonnes/day when last measured on June 19, 2015.

kilauea The wind direction and development of clouds just upstream of Pu’u ‘O’o, prevented us from flying over the collapse pit and the crater itself.

June 27th Lava Flow Observations:

Webcam images show active lava breakouts continuing within an area extending about 8 km (5 mi) northeast Pu’u ‘O’o . Map updates available via remote sensing sources show expansion of the flows since July 6, with gradual northward advance of the most western/northward-pointing branch of the flow field, which would appear at the left edge of the R3 (Mobile Cam 3) webcam view.
