Another view of the flow front and Cemetery Rd./AP‘A‘ā St., looking east. The flow front is entering an open pasture.

HVO geologists can be seen in the pasture mapping the flow front position.

A wider view of the flow front, and its position relative to Pāhoa. This morning the flow front was 1.2 km (0.7 miles) from Pāhoa Village Road, as measured along a straight line. Pāhoa Village Road is at the bottom of the photograph.

Another view of the two lobes that make up the flow front. Vehicles for scale.

Just upslope of the flow front, the flow can be seen here parallel to the dirt road. The flow in this section was only about 30 m (100 feet) wide.

Preview image for video: shows a close-up view of the flow front, and its proximity to Cemetery Rd./AP‘A‘ā St. The transfer station is also shown.

Preview image for video: shows a wider view of the flow front, and pans to the right to show the flow's proximity to Pāhoa.

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 22, 2014, at 1:50 PM is shown in pink, while widening and advancement of the flow as mapped on October 24 at 12:10 PM is shown in red.

A comparison of a normal photograph with a thermal image of the flow front. The white box shows the approximate area of the thermal image. The thermal image shows that high temperatures are concentrated around the leading tip of the flow, which is consistent with lava focused at the front to sustain a higher advance rate.

A closer view of the flow front, which has split into two separate lobes. As of 2 PM, the flow was only 135 m (approximately 150 yards) from Cemetery Rd./AP‘A‘ā St., which spans this photo. HELCO crews can be seen working to protect utility poles along the road.

Another view of the leading tip of the flow, as it moves into the open pasture.

The June 27th flow remains active, and has advanced at an increased rate over the past two days. This afternoon (2 pm), the flow front was pushing ahead as a narrow lobe, and was just 135 m (150 yards) from Cemetery Rd./AP‘A‘ā St. The vent for the June 27th flow is on Pu‘u ‘Ō‘ō (top of photograph), which is nearly 19 km (12 miles) away.

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 20, 2014, at 1:00 PM is shown in pink, while widening and advancement of the flow as mapped on October 22 at 1:50 PM is shown in red.

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 20, 2014, at 1:00 PM is shown in pink, while widening and advancement of the flow as mapped on October 22 at 1:50 PM is shown in red.

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 20, 2014, at 1:00 PM is shown in pink, while widening and advancement of the flow as mapped on October 22 at 1:50 PM is shown in red.

Another view of the flow front, showing the numerous smoke plumes arising from active breakouts burning vegetation at the flow margin. Kaohe Homesteads is in the left side of the photograph.

A comparison of a normal photograph of the flow front with a thermal image. The white box shows the approximate extent of the thermal image. The thermal image shows that active breakouts (white and yellow areas) are focused along the narrow lobe at the leading edge of the flow, but are also scattered for about 2 km (1.2 miles) behind the flow front.

HVO geologists walk over the surface of the flow to track surface breakouts along a portion of the flow margin, about a kilometer (0.6 miles) upslope of the flow front.

Preview image for video: provides an aerial overview of the flow front.

A view of the flow front from the ground, showing the pāhoehoe lava slowly moving through thick vegetation and creating thick plumes of smoke. Frequent methane explosions were occurring. These result from the cooked vegetation releasing methane, which then ignites.
