Kilauea summit tilt began a new deflationary episode yesterday just before noon, and the trend is continuing this morning. The summit lava lake remains active, and the level dropped 11 m (36 ft) with the deflation. The East Rift Zone lava flow is active northeast of Pu’u ‘O’o, and all breakouts remain within 8 km (5 mi) of the vent. The flow does not currently pose a threat to communities. Low levels of seismic activity continue across the volcano.
Tiltmeters at Kilauea’s summit recorded another deflationary episode during the past day, and the deflation continues this morning. The summit lava lake remains active, and the lake level dropped about 11 m (36 ft) between about noon on August 10 and 7:45 am on August 11. The lake level was 63 m (207 ft) below the Overlook crater rim this morning. Seismicity remains at low levels. Summit sulfur dioxide emission rates ranged from 2,600 to 5,500 metric tons/day for the week ending July 28.
Pu’u ‘O’o Observations:
Webcam views of Pu’u ‘O’o during the past day showed no changes in the persistent incandescent crater vents. Seismic activity remains low. The sulfur dioxide emission rate from all East Rift Zone vents was about 500 tonnes/day when measurements were last possible on July 23, 2015.
June 27th Lava Flow Observations:
Webcam views overnight show continued activity on the flow field. The June 27th lava flow is active, with surface flows scattered in 3 areas northeast and east of Pu’u ‘O’o. As mapped during an overflight of the flow field on August 4, all active flows are within 8 km (5 mi) of Pu’u ‘O’o. Location of the most distant flows are marked by smoke plumes that are produced where they are creeping into the forest and burning vegetation.
