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 wider view of the flow front, showing its proximity to AP‘A‘ā St. and the transfer station. The vent for the June 27th lava flow is on Pu‘u ‘Ō‘ō cone, which can be seen in the upper right portion of the photograph. The residential area in the lower left corner is in the western portion of Pāhoa.

A closer view of the flow front from the air, showing the narrow lobe of lava moving along the dirt road. Kaohe Homesteads is in the left side of the photograph. Pu‘u ‘Ō‘ō can be seen in the upper right.

An HVO geologist marks the coordinates of the flow front with a GPS unit.

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.

Preview image for video: was captured at the flow front, and shows a small channelized portion of the pāhoehoe flow pouring over the dirt road embankment. Gas trapped within the flow is released via occasional small bubble bursts.

The June 27th lava flow remains active, and continues to advance towards the northeast along the northern boundary of Kaohe Homesteads subdivision. Over the past day, the leading edge of the flow has moved ahead as a narrow lobe, and covered part of a dirt road. The flow front today was 815 meters (0.5 miles) from AP‘A‘ā St., as measured along a straight line.

This satellite image was captured by the Advanced Land Imager instrument onboard NASA's Earth Observing 1 satellite. Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see. Bright red pixels depict areas of very high temperatures, and show active lava. White areas are clouds.

Gathering this type of information helps USGS scientists to document the changes in beach and nearshore morphology (or form and structure), caused by seasonal variations and storms.

Preview image for video: shows the small explosion of spatter that occurred at Halema‘uma‘u on Sunday, October 19. Spatter landed around the Halema‘uma‘u Overlook (closed to the public).

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 17, 2014, at 7:40 AM is shown in pink, while widening and advancement of the flow as mapped on October 20 at 1:00 PM is shown in red.

Upslope from the flow front, several breakouts are active around the crack system. These surface flows (marked by the smoke plumes) have filled in a ground crack that is immediately north of another crack. The southern crack, marked by the white dotted line, is the main crack that lava is traveling along below the surface.

Pu‘u ‘Ō‘ō Crater remains filled with thick fume, but recent views with the naked eye and thermal camera confirm that little change has occurred in the crater over recent weeks. The fume masks a handful of small incandescent openings on the crater floor.

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 17, 2014, at 7:40 AM is shown in pink, while widening and advancement of the flow as mapped on October 20 at 1:00 PM is shown in red.
