Yesterday, the US Geological Survey downgraded the volcano alert level for the June 27th flow from a “Warning” to a “Watch.”
There is no lava activity whatsoever in the bottom eight miles of the flow from the start of the crack system to the distal tip at Pahoa. The bottom eight miles are virtually inactive with almost no flowing lava, no burning trees, and no smoke or steam. Surface flows anywhere near the geothermal pad have also ceased, leading the USGS to downgrade the volcano alert level for this flow from “Warning” to “Watch.”
Lava still flows up to four or five miles east-northeast of the Pu’u ‘O’o vent and a great deal of surface lava was observed within four miles of the Pu`u `O`o vent. The north flank flow of the vent is still active, with several sizable breakouts seen there. Lava continued to flow in pahoehoe toes and larger outbreaks at numerous places downslope from the vent, and is weakly burning the forest about a mile and a half below Pu’u ‘O’o. Perhaps the most vigorous surface lava is about four miles below the vent, but still several miles from the beginning of the crack system.
