An HVO geologist maps the margin of the June 27th lava flow using GPS. Mapping on foot like this can be difficult in thick forest due to downed trees covering the edge of the flow.

A pāhoehoe toe oozes out of the northern margin of the June 27th lava flow in thick forest, about 300 meters (328 yards) upslope of the leading edge of the flow

Sluggish pāhoehoe breakouts were present along the south margin of the June 27th lava flow on Saturday morning about 100 meters (109 yards) upslope of the leading edge of the flow.

A methane explosion in the ground adjacent to the flow margin threw these blocks of older lava, some up to half a meter (yard) in diameter, a distance of several meters (yards) onto the flow surface. Just to the left of the geologists is a crater of disrupted ground, with overturned blocks of older lava up to a meter (yard) in size.

This small-scale map shows the June 27th lava flow in Kīlauea's East Rift Zone in relation to lower Puna. The area of the flow on October 30, 2014, at 12:00 PM is shown in pink, while widening and advancement of the flow as mapped on October 31 at 12:25 PM is shown in red.

A few small breakouts remain active near the transfer station, seen at lower right. One breakout, active for several days now, is slowly creeping toward the southern edge of the transfer station, and was about 35 m away today. Another breakout started overnight on the south side of the flow opposite from the lobe heading toward the transfer station.

A hole is left behind by a large tree that was surrounded by lava, burned through at its base, and collapsed onto the solidified flow surface a short time before this photo was taken. The end of the tree trunk is glowing, and flames from burning wood are emanating from the hole. This represents an under appreciated hazard of the lava flow field.

This is a closer view of the leading part of the flow, looking toward Pāhoa Village Road, which cuts across the top of the photo. The smoke marks where an active breakout is advancing downslope along the north side of the finger which stalled yesterday after crossing through private property.

This map uses a satellite image acquired in March 2014 (provided by Digital Globe) as a base to show the area around the front of the June 27th lava flow. The area of the flow on October 30, 2014, at 12:00 PM is shown in pink, while widening and advancement of the flow as mapped on October 31 at 12:25 PM is shown in red.

The June 27th lava flow remains active in and upslope from Pāhoa. Yesterday, the tip of the flow was stalled about 155 meters (170 yards) from Pāhoa Village Road, which crosses the photo at lower right. A few small toes of pasty lava continue to leak from the sides of the flow just upslope from the front today.

This large-scale map shows the distal part of the June 27th flow in relation to nearby Puna communities. The area of the flow on October 30, 2014, at 12:00 PM is shown in pink, while widening and advancement of the flow as mapped on October 31 at 12:25 PM is shown in red.

The June 27th lava flow came into contact and inflated against an artificial berm on private property on Thursday afternoon. Note that the flow has inflated to a level much higher than that of the berm.

Minor breakouts of lava ooze from the margin of the June 27th lava flow on the afternoon of Thursday, October 30, 2014. These breakouts are located about 100 meters (110 yards) behind the leading edge of the flow.

Lava near the leading edge of the June 27th flow oozed over a concrete slab and towards a tangerine tree before solidifying Thursday afternoon.

This map uses a satellite image acquired in March 2014 (provided by Digital Globe) as a base to show the area around the front of the June 27th lava flow. The area of the flow on October 28, 2014, at 1:00 PM is shown in pink, while widening and advancement of the flow as mapped on October 29 at 11:30 AM is shown in red.

A comparison of a normal photograph with a thermal image of the flow front. The white box shows the extent of the thermal image. The thermal image shows that most of the activity in this region is focused at the leading edge of the flow (white and yellow areas show active surface lava).
