The leading tip of the June 27th flow has not advanced significantly over the past week, and remains roughly 500 meters (550 yards) upslope of Highway 130, west of the fire and police station.

Breakouts persist upslope, however, and these areas of activity can be spotted in this photograph by small smoke plumes where the lava is burning vegetation on the flow margins.

This comparison of a normal photograph and a thermal image shows the position of active breakouts relative to the inactive flow tip. The white box shows the rough extent of the thermal image on the right.

In the thermal image, active breakouts are visible as white and yellow areas. Although active breakouts are absent at the inactive tip of the flow, breakouts are present just a short distance behind the tip, and are also scattered further upslope.

A small breakout from the lava tube is burning forest just left of the center of the photograph. In the upper left, thick fume is emitted from Puʻu ʻŌʻō. Near the top of the photograph, the snow-covered peak of Mauna Loa can be seen.
