Kilauea Summit Update – 7/1/15
Hawaiian Volcano Observatory conducted an overflight assessment of the Puʻu ʻŌʻō and June 27, 2014 lava flow areas on Tuesday. During the overflight geologists, noticed two incandescent vents in the southern portion of the Puʻu ʻŌʻō crater and a “robust outgassing plume coming from the wall of a pit in the northeast part of the crater.”
In addition, HVO reported observations of a crusted-over lava pond deep in a large circular pit in the west area of the Puʻu ʻŌʻō crater. This pond was reportedly bubbling over along its own margin.
Observations of the June 27, 2014 lava flow conducted during the Tuesday overflight confirmed recent webcam visuals. HVO reports that active lava breakouts were visible and extended to the northeast of Puʻu ʻŌʻō by about 5 miles.
Between HVO’s June 19 overflight assessment and Tuesday’s assessment, geologists reported seeing no downslope advancement of the June 27, 2014 flow. Expansion of flow margins, within moderate levels, was observed.
Tilt at the summit of Kilauea remains flat, according to HVO, who reported that tiltmeters at the summit have not record significant tilt trends since Friday.
Lava within the Overlook crater’s lava lake measured Wednesday morning has dropped about 15 feet since the previous day. The surface of the lake is now about 155 feet below the current crater rim.
Seismic rates below Kilauea’s summit remain at background levels as bursts of seismic tremor in association with periods of vigorous spattering of the lava lake continues.
