After four months of continuous activity, lava effectively ceased flowing into the ocean and coastal flats due to a large surface breakout high atop, and above, the Pulama Pali.
On this mornings USGS/HVO Kilauea status update they had this to say about this unfolding event: Lava from the TEB vent flowed a short distance down slope before coming to the surface in the saddle between two rootless shields at around the 2,000 ft elevation. A few spots of incandescence were recorded by webcam there last night; in addition, persistent MODIS and GOES thermal anomalies suggest at least a low level of continuing activity. HVO geologists will conduct an overflight and inspection of the area tomorrow if the weather is good. In Kalapana, flows and the ocean entries at Puhi-o-Kalaikini delta have stalled.

The lava fields and tube system will continue to hold molten lava beneath the ground for weeks and months whether they become reenergized with fresh lava or not. In past years we have had complete pauses of lava flowing down the pali tube system for a few days and then suddenly they fire back up to previouse intensity. If the recent rootelss shield tube rupture has completely severed then this scenario is far less likely I would think.
The July Quarry Flow of this year began in late June into early July after the TEB eruptive site fed lava part way towards the top of the Pulama Pali where it re-formed into large mounds that swelled with molten lava, and storing it there. These mounds are termed ‘rootless shield's; rootless meaning not connected to the main magma source or vent, and building up on top of, or near to, an established lava tube system.
I hiked up to the base of that rootless shield area on July 9th , two days after the shields had burst open and sent major rivers of lava part way down the pali, which was the beginning of the lava flow that covered such a large area of coastal flats land, covered roads and surged into the edge of Kalapana Gardens July 17th & 18th, destroyed a home and poured into the ocean July 25th , and claimed a second occupied home last Saturday, November 27th before ending two days later when the rootless shield broke out.

It will be very interesting to see what comes next with these big changes to the TEB eruption… Will we get an entirely new surface flow and subsequent new ocean entry? Pele will be the director of all further island building, just as she has done for millions of years right here…
