- Little activity and little advance at the flow front this morning, civil defense reports.
- Small breakout flows upslope from the leading edge along the north flank have also decreased in activity.
- Inflationary tilt at the summit of Kilauea began Monday evening and is continuing as of Tuesday morning, reports USGS Hawaiian Volcano Observatory. Scientists believe there is a connection between summit inflation and increased activity on the lava flow.
This morning’s assessment shows lava flow activity continues along the edges of the front or leading surface lava flow however, the flow front had not advanced much since yesterday. The small breakout flows upslope from the leading edge along the north flank have also decreased in activity and had advanced approximately 20 yards in a north direction. All current flow activity does not pose an immediate threat to area communities.
No evacuation is needed at this time and area residents will be given adequate notice to safely evacuate should that be necessary.
Smoke conditions were light to moderate with light trade winds out of the northeast and a light rain was present in the area. There is no fire threat at this time.
HELCO crews are continuing with work in the Government Beach road area. This will result in the road being blocked and the access will be limited to beach road residents only to minimize disruption and delays to the operations.
The public is reminded that the flow is not visible and cannot be accessed from any public areas. Access to the Kaohe Homesteads subdivision will remain restricted to area residents only.Hawaii County Civil Defense on Sept. 27
The June 27th lava flow remains active. An HVO overflight on Monday observed breakouts of lava where the flow first enters the crack system about 8 km (5 mi) behind the stalled front, and where it exits the crack system about 3 km (2 mi) back from the front. At the leading edge of the flow, two lobes of weak surface activity were observed at 125 m (410 ft) and 580 m (1900 ft) behind the front. Both lobes are creeping northeast around the north side of the existing flow. Lava continues to move through the tube from Puʻu ʻŌʻō, but the volume is low compared to that measured two weeks ago, during the period of rapid flow advance.
Puʻu ʻŌʻō Observations: There was no net change in ground tilt at Puʻu ʻŌʻō over the past day. Glow was visible overnight above several outgassing openings in the crater floor. The most recent sulfur-dioxide emission-rate measurement for the East Rift Zone was 550 tonnes per day (from all sources) on September 25, 2014. Seismic tremor is low and constant.
Summit Observations: After holding steady for much of Monday, inflationary tilt began Monday evening and is continuing as of Tuesday morning. The lava level within the summit vent rose accordingly to about 50 m below the Overlook crater rim. USGS Hawaiian Volcano Observatory on Sept. 27
