A close up view of the ‘A‘ā channel.

This image shows a thermal map of the flow on the pali and coastal plain, created from airborne thermal images. White pixels are hot, and show areas of active surface breakouts. The background image is a satellite image collected before the current lava flow was active.

Map of Kīlauea's active lava flow as of July 19, 2016. Red shows the extent of new breakouts since July 8; pink shows the flow prior as of July 8, and gray shows areas covered by earlier Pu‘u ‘Ō‘ō lava flows (1983-2016).

The active lava flow continues to creep across the coastal plain on Kīlauea's south flank. Breakouts of pāhoehoe (foreground) are fed by lava traveling through lava tubes from the Pu‘u ‘Ō‘ō vent and down Pūlama pali (top background). USGS photo.

The HVO field crew mapped new breakouts on the lava flow by recording GPS points along the active flow margin.

A long, hot hike was not needed to see red lava today. Vigorous spattering from Kīlauea Volcano's summit lava lake was visible from the Jaggar Museum Overlook in Hawai‘i Volcanoes National Park as of this afternoon. The lava lake surface, measured at 25 m (82 ft) below the vent rim this morning, was high enough for the spattering to be seen from afar.

Kīlauea Volcano's lava flow remains active, with pāhoehoe lobes, like the one shown here, slowly advancing on the coastal plain. Breakouts upslope of the leading edge continue to widen the flow margins. Today, the active flow front was approximately 850 m (0.5 miles) from the ocean, and 720 m (0.4 miles) from the road.

The flow remains active on the pali and coastal plain, with scattered breakouts of pāhoehoe lava. Over the past week, however, the leading tip of the flow has advanced only a short distance. Today, the flow front was 850 m (0.5 miles) from the ocean. In this photograph, the current lava flow is the lighter color area in the center of the photo.

Only a few short sections of road in Royal Gardens subdivision remain uncovered by lava. In this kipuka, about 200 m (220 yards) of Orchid Street is still exposed.

This photograph looks downslope at the uppermost section of the Episode 61g flow. The vent is in the lower left corner of the photo. Several collapses have occurred over the lava tube, and the trace of the tube can be seen by the fuming sources extending downslope.

The large hole on the northeast flank of Pu‘u ‘Ō‘ō remains open, providing a view of forked lava streams. Since the last overflight on Friday, July 15, the lava streams have started to crust over, reducing the glow in the pit.

This map shows recent changes to Kīlauea's East Rift Zone lava flow field. The area of the active flow field as of July 8 is shown in pink, while widening and advancement of the active flow as mapped on July 19 is shown in red. Older Pu‘u ‘Ō‘ō lava flows (1983-2016) are shown in gray.

The flow front remains active on the coastal plain, but has only moved about 60 m (~200 ft) closer to the ocean in the past three days. As of midday on July 15, the slow-moving pahoehoe is roughly 870 m (~0.5 mi) from the ocean. Activity upslope continues to widen the flow margins. The light gray surface in this image is the new pahoehoe of the 61G flow.

This map is a georeferenced thermal image mosaic showing the distribution of active and recently active breakouts on the Pūlama pali and coastal plain. The thermal images were collected during a helicopter overflight on July 15. The episode 61g flow field as mapped on July 8 is outlined in yellow to show how the flow has changed.

This nitrogen-fixing lichen, Stereocaulon vulcani, is frequently abundant on ‘A‘ā lava flows on the Island of Hawai‘i, particularly in wet environments. Photo courtesy of Tim Tunison.

This satellite image was captured on Wednesday, July 13, by the Advanced Land Imager instrument onboard NASA's Earth Observing 1 satellite. The image is provided courtesy of NASA's Jet Propulsion Laboratory. Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see.

This image shows a thermal map of the flow on the pali and coastal plain, created from airborne thermal images. White pixels are hot, and show areas of active surface breakouts. The background image is a satellite image collected before the current lava flow was active.

Surface breakouts remained active on the pali and coastal plain, but the leading tip of the flow has advanced little since mapping on Sunday. This morning, the flow front was about 940 m (0.6 miles) from the ocean. Activity upslope of the flow front was widening the flow margins. In this photo, the active flow is the lighter colored area.
