On October 26, 2014, lava from Kilauea Volcano's "June 27 breakout" flow continues to advance towards the northeast, approaching the small town of Pahoa, Hawaii. 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 Pahoa cemetery. #

On the morning of June 27, 2014, elevated pressure within Kilauea's Pu'u 'O'o cone reached a breaking point, with magma intruding through the cone and erupting from fissures on the northeast flank. These new vents fed a vigorous channelized flow that had reached about 1.5 km (0.9 miles) northeast of Pu'u 'O'o by 11 am. #

By July 18, the front of the June 27th lava flow, seen here as the silvery lava, surrounds what little remains of Pu'u Kahauale'a, a forested volcanic cone several hundred years old. #

On August 12, a skylight reveals the fluid lava stream within the main tube of the June 27 lava flow, revealing complex structure within the lava tube. The bright incandescent area is the fluid lava stream, which was slowly but steadily flowing through the tube. #

August 14. This collapse of a portion of the roof above the June 27 flow has produced a skylight, and a direct view of the fluid lava stream several meters beneath the surface. #

September 1, near the leading edge of the lava on the surface, a swiftly moving stream of lava pours into a deep ground crack (center). Pu'u 'O'o is at the top of the photograph. #

On October 22, 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. #

On October 24, Hawaii Electric Light Company crews enclose utility poles in insulating jackets and cinder/cement barriers, working to protect the poles along Pahoa's Cemetery Road from the encroaching lava flow. #

The June 27th lava flow crossed Apa'a 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. The hope is that the protective insulation and cinder/cement barrier around the pole will prevent it from burning through. #

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

October 25, some of the flow front had the appearance of "slabby" pahoehoe, which is the type of lava in which the surface consists of numerous broken, overturned slabs. #

On October 27, a wider view of the flow, showing its proximity to Pahoa Village Road. Pahoa Village Road spans the bottom portion of the photograph, Hawaii Electric Light Company trucks visible, working to protect utility poles. The flow front was heading towards a low spot on the Pahoa Village Road, between Apa'a St. and the post office (area at bottom center of this photo). This photo was taken at 11:30 am October 27, when the flow front was 540 meters (0.3 miles) from Pahoa Village Road. #

A Google Maps street view of the low point in Keaau-Pahoa Road, where geologists predict the June 27 flow is headed within the next few days. The lava is approaching from the right side of the image. See it on Google Maps, here. #
