- There has been no advancement of the lava flow in any of the down slope flow areas. Civil Defense reports there are multiple breakouts along both margins upslope of the flow front, which “provide indication that the tube system continues to be supplied and lava from the source is making its way to the down slope areas.” All current activity does not pose an immediate threat to area communities, Civil Defense says.
- Smoke conditions were light to moderate with a light south wind blowing the smoke in a north/northeast direction
Hawaii County Civil Defense message for Feb. 10th:
This morning’s assessment continues to show no advancement of any of the down slope flow areas. Multiple surface breakouts and breakouts along both margins upslope of the flow front continue and provide indication that the tube system continues to be supplied and lava from the source is making its way to the down slope areas. All current activity does not pose an immediate threat to area communities. The Hawaii County Civil Defense Agency and Hawaiian Volcano Observatory are maintaining close observations of the flow. Residents and businesses down slope will be informed of any changes in flow activity and advancement.
Smoke conditions were light to moderate with a light south wind blowing the smoke in a north/northeast direction. Smoke conditions may increase in some areas and individuals who may be sensitive or have respiratory problems are advised to take necessary precautions and to remain indoors. A light rain was occurring in the area this morning and no burning activity related to the recent brush fire was noted. There is no fire threat to any nearby communities and the fire conditions will be monitored closely.
On behalf of the Hawaii County Civil Defense Agency and our partners we would like to thank everyone for your assistance and cooperation. Hawaii County Civil Defense on Feb. 10 at 7:15 a.m. HST
Activity Summary: Kīlauea Volcano continues to erupt at its summit and from its East Rift Zone. The inactive distal tip of the June 27th lava flow remains roughly 500 m (~550 yd) from Highway 130 in the area west of the Pāhoa Fire and Police Stations. The flow has not advanced downslope in about 2 weeks, but many breakouts remain active upslope. Tiltmeters located at the summit recorded little change in the past 24 hours; a tiltmeter at Puʻu ʻŌʻō recorded inflationary tilt that correlates with rainfall at the vent. No significant changes have occurred at the volcano during the past 24 hours.
June 27th Lava Flow Observations: Observers on the Civil Defense overflight Tuesday morning report continued surface flow activity upslope of the inactive distal flow tips. Webcam images also show these lowermost breakouts and the breakout near Puʻu ʻŌʻō were active during the past 24 hours.
Puʻu ʻŌʻō Observations: A small amount of inflationary tilt was recorded by the tiltmeter on the north flank of Puʻu ʻŌʻō during the past 24 hours, which correlates well with rainfall at the vent. Webcams show a few spots of fluctuating glow emanating from small pits within the crater, and seismic tremor has remained low. The rate of sulfur dioxide emission from all East Rift Zone vents was about 200 tonnes per day, measured on January 7 (unfavorable wind conditions have prevented more recent measurements).
Summit Observations: Tiltmeters operating around the summit recorded no change in tilt during the past 24 hours. The level of lava within the summit eruptive vent remained relatively steady in the past 24 hours with little variation. Emission rates of sulfur dioxide ranged from around 4,400 to 5,100 tonnes/day during the week ending on January 27 (unfavorable wind conditions prevented measurements during the past week). There was no significant change in seismicity on Kīlauea during the past day; seismic tremor at the summit remained low.USGS Hawaiian Volcano Observatory on Feb. 10 at 9:06 a.m. HST
