Activity and advancement has reached a lull for the June 27 lava flow.

Hawai’i County Civil Defense’s Wednesday morning overflight assessment showed that the leading edge of the flow front continues to remain stalled about 0.5 miles from the Highway 130 and Pahoa Village Road intersection, as it has for about a week and a half. The once active breakout on the south margin of the flow has also remained stalled along with the flow front.

Civil Defense reported that the active and recently slow moving breakout 1-1.5 miles upslope from the stalled flow front has shown no noticeable activity since Tuesday. The last noted advancement of this north breakout is between Monday and Tuesday morning, when it advanced 20 yards in a northeast direction in that time period.

Hawaiian Volcano Observatory observed during its Tuesday afternoon overflight that small breakouts were active in an area in the crack system that has persistent activity, near the True/Mid-Pacific geothermal well pad, about 4 miles from Pahoa. HVO officials say that no additional breakouts were observed upslope from the well pad area.

Additional activity also continues above the flow front and in further upslope areas along both the south and north margins. Civil Defense says none of the activity is posing any immediate threat to communities in the area and, along with HVO, will continue to monitor activity.

A brush fire that broke out on Tuesday evening as a result of the lava flow activity has been contained within the fire break. Brush fire activity as of Wednesday morning was limited to hot spots and smoldering, according to Civil Defense. The Hawai’i Fire Department remains on the scene monitoring fire conditions.

For the third day in a row heavy smoke and vog conditions were reported as a south-west wind was blowing smoke in a northeast direction over lower Puna and into Hilo. Officials advise individuals who are sensitive or who have respiratory issues to take necessary precautions and remain indoors.
