Lava Flow Update – Activity at Flow Front “Appears” to Stall But Surface Flows Remain Active

The June 27th flow remains active, but surface flows at the very farthest reaches of the flow appear to have stalled today.

The lava flow front consisted of an isolated pad of lava that emerged from a deep ground crack several days ago. Today, this pad of lava appeared inactive at the surface, with no sign obvious activity in the adjacent crack. On today’s overflight, the farthest active surface flows were on the main body of the June 27th flow, and were 8.5 km (5.3 miles) from the vent on Puʻu ʻŌʻō, or about 6 km (3.7 miles) from the eastern boundary of the Wao Kele o Puna forest reserve.

A closer view of the southern lobe of the June 27th lava flow. Smoke plumes originate from active surface breakouts, the farthest today reached 8.5 km (5.3 miles) from the vent on Puʻu ʻŌʻō. The spot at which this lobe plunged into a deep ground crack last week can be seen near the bottom of the photograph. In the upper right portion of the photograph, smoke originating from active breakouts on the northern lobe can be seen.

A comparison of the normal photograph (see above) of the south lobe of the June 27th flow with an equivalent view from the thermal camera. The thermal camera clearly shows the extent of the farthest active breakout, which was relatively small.

Top: Another view of the south lobe of the June 27th flow, which plunged into a deep ground crack last week (this spot is visible at the right side of the photograph). This wide view, looking west, also shows another deep crack nearby, a short distance to the south of the active flows (which are producing the smoke plumes). This immediate area contains many ground cracks, which are part of Kīlauea’s East Rift Zone. Puʻu ʻŌʻō can be seen in the distance.

Bottom: The isolated pad of lava that emerged from the deep ground crack several days ago did not have any active breakouts at the surface today, but incandescent lava could be seen in numerous cracks on the surface. This likely represents lava that had ponded within the flow and remains hot, but immobile.
