Another wide view of the flow front and its position relative to Pāhoa.

The June 27th lava flow, named for the date in 2014 that the flow started, threatened to inundate different parts of Pāhoa and cross Highway 130 between September 2014 and March 2015. The leading tip of the flow is about 18 km (11 mi) in a straight line distance from the vent located on the flank of Pu‘u ‘Ō‘ō.

This annotated photograph shows the notable features around the flow front. The photo was taken at 11:30 am, and also shows the distance the flow front has traveled between Cemetery Rd./AP‘A‘ā St. and Pāhoa Village Rd.

A slightly closer view of the flow front. AP‘A‘ā St. is in the lower portion of the photograph, and the transfer station is in the lower right. Pāhoa Village Road is in the upper left portion of the photograph.

Preview image for video: This Quicktime movie, taken at 11:30am, gives an aerial overview of the flow front and its position relative to Pāhoa. The movie is fairly large in size and may take several minutes to download.

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 26, 2014, at 12:30 PM is shown in pink, while widening and advancement of the flow as mapped on October 27 at 11:30 AM is shown in red.

A typical portion of the pāhoehoe flow margin near the flow front, just downslope of Cemetery Rd./AP‘A‘ā St. The horizontal incandescent cracks seen in the center and right portions of the photo indicate that the flow was inflating. pāhoehoe inflation is driven by continued supply of lava beneath the surface crust, which slowly raises the surface.

Some of the flow front had the appearance of "slabby" pāhoehoe, which is the type of pāhoehoe in which the surface consists of numerous broken, overturned slabs.

An HVO geologist walks across the surface of the flow, which covers the short access road to the cemetery. As is typical for pāhoehoe, the flow has inflated over the past day and was chest high in many places.

The area of the flow on October 24, 2014, at 12:10 PM is shown in pink, while widening and advancement of the flow as mapped on October 25 at 5:00 PM is shown in red.

After slowly moving downslope from Kīlauea Volcano’s East Rift Zone since June 27, 2014, this active lava flow in Hawaiʻi reached the town of Pāhoa just before Halloween, destroying roads, a cemetery, and private property in this community.

An HVO geologist takes a GPS waypoint at the flow front. This measurement is done sequentially throughout the day to measure flow advance rates. The flow front was moving through tall grass in an open field downslope of AP‘A‘ā St. today.

A section of the flow margin near the flow front, showing a continuous horizontal incandescent crack that indicates ongoing flow inflation. HVO geologist for scale. The flow here was only about a meter thick, but slightly farther upslope where the lava has had more time to inflate the thickness was closer to two meters.

One of the rotated surface slabs presses against the fencing that runs along the small road to the cemetery.

As of 10 AM, HST, on October 26, 2014, the June 27th flow front remains active and continues to advance towards the northeast. A portion of the front is still moving through the open field (shown here), while the leading tip of the flow has advanced through the Pāhoa cemetery.

The June 27th lava flow crossed AP‘A‘ā Street / Cemetery Road at 3:50 AM, HST, Saturday morning, October 25, 2014. In this photo, which was taken at about 9 AM Saturday, the flow is moving from right to left, with burning asphalt visible along it's NW margin. A utility pole, far right, was surrounded by lava but remained standing at the time of the photo.

At 11 AM Saturday, the June 27th flow was advancing down the grassy driveway that leads to the Pāhoa cemetery. This view is looking upslope towards AP‘A‘ā Street along the cemetery driveway.

The June 27th lava flow advances across the pasture between the Pāhoa cemetery and AP‘A‘ā Street, surrounding a barbed wire fence.
