This map shows recent changes to Kīlauea's active East Rift Zone lava flow field. The area of the flow on June 30 is shown in pink, while widening and advancement of the flow as of July 7 is shown in red. The yellow line is the active lava tube. Pu‘u ‘Ō‘ō lava flows erupted prior to June 27, 2014, are shown in gray.

Active pāhoehoe lava is scattered over a broad area northeast of Pu‘u ‘Ō‘ō, but has not advanced significantly over the past month. Today, the farthest active lava was about 7.5 km (4.7 miles) from the vent on Pu‘u ‘Ō‘ō, with the leading tip of this breakout burning vegetation. Aerial view towards the southwest. Pu‘u ‘Ō‘ō is in the upper left.

A closer view of the one of the pāhoehoe breakouts near Pu‘u Kahauale‘a. The dark flakes on the surface are bits of crust from the underlying flow that get stuck to the front of the newer flow, and end up on the top surface as the nose of the new flow inflates.

This map overlays a georeferenced thermal image mosaic onto the flow field change map to show the distribution of active and recently active breakouts. The thermal images were collected during a helicopter overflight of the flow field today (June 30). The June 27th flow is outlined in green to highlight the flow margin. The yellow line is the active lava tube.

This 1891 map shows much of the saddle between Mauna Kea (at top of map) and Mauna Loa. Lava flows depicted as black irregular shapes in the lower half of the map were erupted from Mauna Loa, with labeled ages ranging from "ancient" to 1881.

This satellite image was captured on Tuesday, June 23, 2015 by the Landsat 8 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.

Scattered breakouts remain active northeast of Pu‘u ‘Ō‘ō on the June 27th lava flow, but have not advanced significantly over the past month. This photo shows the farthest reach of active lava on the flow field today, which was about 8 km (5 miles) northeast of the vent on Pu‘u ‘Ō‘ō. Minor brush fires were active where lava was entering forest.

Little has changed in Pu‘u ‘Ō‘ō over the past month, and a small lava pond still exists within the circular pit in the western portion of the crater. This pit can be seen through the fume in this photo, and a tiny area of incandescence at the edge of the active pond is barely visible.

Scattered breakouts were active at the margins of the June 27th flow, with only minor expansion of the flow margins over the past two weeks. This photo shows an active breakout on the south margin of the June 27th flow, moving over older ‘A‘ā from Pu‘u ‘Ō‘ō.

A natural levee separates the smooth surface of the active lava lake from overflows of pāhoehoe in foreground. Photo by Thomas A. Jaggar, Jr.
