The June 27th lava flow remains active with scattered breakouts northeast of Pu‘u ‘Ō‘ō. The farthest active breakout today was about 6.5 km (4 miles) from Pu‘u ‘Ō‘ō. This photograph shows activity along the northern flow boundary, where breakouts continue to burn vegetation.

This view looks west towards Pu‘u ‘Ō‘ō, which can be seen in the upper left. The most distant active breakouts today were located near the center of the photograph, at a spot roughly 6.5 km (4 miles) from Pu‘u ‘Ō‘ō.

This wide view shows the lava lake active within the Overlook crater, which is set within the larger Halema‘uma‘u Crater. There have been no major changes in the lake in recent weeks. This morning the lava lake was roughly 60 meters (200 feet) below the rim of the Overlook crater. The dark region surrounding the Overlook crater is lava that spilled out onto the floor of Halema‘uma‘u Crater in April and May of this year, when the lake level was much higher.

There has been no significant change on the flow field northeast of Pu‘u ‘Ō‘ō, and some of the active flows continue to creep into the forest along the north edge of the flow field, as seen here, looking roughly northwest. Activity has been remarkably stable and consistent, with no overall advancement of the flows, for the last several weeks.

View of Pu‘u ‘Ō‘ō crater, looking northwest. The floor of the crater was paved in late August by lava that erupted from a vent at the northeast edge of the crater, which is the heavily fuming area to the right. There are also vents at the southeast edge of the crater (note the incandescent vent just left of center) and at the northwest edge (hidden by fume just above center). A western pit, outside the left edge of the crater (hard to see in this photo), hosts a small sluggish lava pond. The vent supplying the June 27th lava flow is on the flank of Pu‘u ‘Ō‘ō beyond the right edge of the photo.

Photo of Pu‘u ‘Ō‘ō west of the crater, looking north-northwest. The west edge of the crater is to the right. The western pit, with the lava pond, is just above and left of center. Notice the vaguely arcuate line of fume that wraps from the south edge of the crater, around the western pit, and back to the northwest edge of the crater in the background. This fuming arc corresponds closely to the rim of the crater that was present in 2011. The surface of the crescent-shaped area bounded by this arc is sulfur stained and, when on the ground there, is found to be very hot, suggesting that there may be pockets of magma below the ground there. In time, other pits may form in this area, or the western pit may continue to widen, and eventually the entire crescent-shaped area could collapse and become part of the crater again.
