The lava lake at Kilauea’s summit remains active. Summit tiltmeters recorded slow deflationary tilt. The East Rift Zone lava flow northeast of Pu’u ‘O ‘o remains active within 8 km (5 mi) of the vent and does not currently pose a threat to communities. Normal levels of seismic activity continue across the volcano.
The lava lake level fluctuated but remained at about 58 m (190 ft) below the floor of Halema’uma’u as measured Friday morning. Seismic tremor associated with spattering on the surface of the lava lake continued. Tiltmeters at Kilauea’s summit recorded a gentle transition to weak deflationary ground tilt. Winds were weak and variable; the summit gas plume is rising to the south or southwest this morning. Summit sulfur dioxide emission rates ranged from 1,700 to 2,700 metric tons per day for the week ending September 1.
Pu’u ‘O ‘o Observations:
Normal activity (continuous gas release and glow at night) continued from vents within the crater. The sulfur dioxide emission rate from all East Rift Zone vents was about 390 metric tons per day when measurements were last possible on August 13, 2015.
June 27th Lava Flow Observations:
Clear webcam views yesterday and overnight showed continued scattered activity on the flow field northeast of Pu’u ‘O ‘o. Active lava breakouts remained within about 8 km (5 mi) of Pu’u ‘O ‘o and were not threatening any communities. Some breakouts are marked by smoke plumes where lava is creeping into the forest.
