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.

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.

Photograph shows a USGS scientist navigating an all-terrain vehicle equipped with GPS, collecting topographic data on Rio Del Mar State Beach in Aptos, California. 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 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 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.

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.

A comparison of a normal photograph of the flow front with a thermal image. Although the leading edge of the flow has advanced only a slight amount over the past week (about 100 m, or 110 yards), active portions behind the flow front have moved at a faster rate.

The June 27th lava flow remains active, with no significant advancement of the flow front since Friday, Oct 17. The flow is active along the northern boundary of Kaohe Homesteads subdivision, with brush fires along the flow margins creating thick plumes of smoke.

A collapse of rock from the wall of Halema‘uma‘u Crater occurred yesterday (Sunday, October 19) around 1:15 am, with rocks impacting the lake and triggering an explosion of spatter. The scar left by this collapse is visible as the light-colored area marked in the photo.

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 15, 2014, at 10:30 AM is shown in pink, while widening and advancement of the flow as mapped on October 17 at 7:40 AM is shown in red.
