The contact (red arrow) between Huckleberry Ridge Tuff ignimbrite members A and B is marked by a time break of probably weeks to a month or so.

This large-scale map shows the distal part of the June 27th flow in relation to nearby Puna communities. The black dots mark the flow front on specific dates. Small breakouts were scattered across the surface of the flow upslope from the stalled front.

The June 27th lava flow remains active, with breakouts a short distance behind the stalled flow front.

Preview image for video: gives a quick aerial overview of activity at the front of the June 27th lava flow. The flow remains active, with slow-moving breakouts about 2.5 km (1.6 miles) upslope of Apa‘a St. and 3.5 km (2.2 miles) from Pāhoa Village Road.

This small-scale map shows the June 27th flow in Kīlauea's East Rift Zone in relation to lower Puna. The area of the flow on September 26, 2014, at 11:15 AM is shown in pink, while widening and advancement of the flow as mapped on September 29 at 10:30 AM is shown in red.

A normal photograph of the front of the June 27th lava flow is compared here with an equivalent view from a thermal camera. The thermal image shows the extent of active breakouts more clearly. These breakouts have been advancing slowly over the past few days, and were present a short distance upslope of the stalled flow front.

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. Surface activity near the flow front was advancing slowly northeast in two lobes. The lobe farthest from the vent (the closest to Pāhoa) was about 125 m (137 yards) behind the stalled flow front.

This small-scale map shows the June 27th flow in Kīlauea's East Rift Zone in relation to lower Puna. The area of the flow on September 24, 2014, at 10:45 AM is shown in pink, while widening and advancement of the flow as mapped on September 26 at 11:15 AM is shown in red.

This large-scale map shows the distal part of the June 27th flow in relation to nearby Puna communities. The black dots mark the flow front on specific dates.

Annotated photo showing the terminus of the June 27th lava flow. Small, sluggish breakouts remain active upslope from the stalled front of the flow, near Kaohe Homesteads. More vigorous breakouts are active even farther upslope, midway along the length of the flow and on a pad of lava within the crack system.

This map uses satellite imagery acquired in March 2014 (provided by Digital Globe) as a base image to show the area around the front of the June 27th lava flow. The flow front closest to the transfer station was inactive, but small, sluggish breakouts were scattered across the surface of the flow upslope from the stalled front.

The leading edge of the June 27th flow stalled over the weekend, but active breakouts persist near the flow front, a short distance behind this stalled front. Today, lava was slowly advancing on a different front, along the north margin of the flow.

Another view of the flow front region, looking northeast. Pāhoa can be seen near the top of the photograph, and is about 3.3 km (2.1 miles) from the stalled flow front.

The thermal image on the right provides a different view of the flow front, and clearly shows the scattered breakouts in this area. Most of these active breakouts were at, or upslope from, the slowly advancing flow front on the north margin of the flow. The leading edge of the stalled flow front, not surprisingly, did not have any active breakouts.

This large-scale map shows the distal part of the June 27th flow in relation to nearby Puna communities. The black dots mark the flow front on specific dates. The latitude and longitude of the most-active, slowly advancing breakout on September 24 was 19.473080, -154.981264 (Decimal degrees; WGS84).

This small-scale map shows the June 27th flow in Kīlauea's East Rift Zone in relation to lower Puna. The area of the flow on September 19, 2014, at 11:45 AM is shown in pink, while widening and advancement of the flow as mapped on September 24 at 10:45 AM is shown in red.

Several skylights provided views into the June 27th lava tube today, and the fluid lava stream could be seen moving downslope.

Preview image for video: shows an HVO geologist sampling lava on the June 27th lava flow using a rock hammer. The lava is placed into a bucket of water to quench the sample. Lava samples like this are routinely collected for chemical analysis, which provides insight into the magmatic system feeding the eruption.
