This map overlays a georegistered mosaic of thermal images collected during a helicopter overflight of Kīlauea's active East Rift Zone lava flow west of Kaohe Homesteads on February 27 at about 11:35 AM. The perimeter of the flow at that time is outlined in yellow.

Another view of the leading tip of the June 27th flow, looking downslope towards Highway 130.

This photograph looks southeast at the fork in the June 27th flow that is just west of Kaohe Homesteads. The east branch (top portion of photo) crossed AP‘A‘ā St. and entered Pāhoa in late October, and this branch is now inactive. The west branch (lower portion of photo) has headed towards areas at the north end of Pāhoa, and remains active.

The breakout on the north flank of Pu‘u ‘Ō‘ō that began last weekend remains active, but has advanced only a minor distance over the past four days. The new breakout is visible as the light-colored area just to the right of the center of the photograph. Pu‘u ‘Ō‘ō Crater is in the upper left portion of the photograph.

A closer look at some of the activity at the breakout on Pu‘u ‘Ō‘ō.

This view looks north and shows Pu‘u ‘Ō‘ō. Much of the original cone has been covered by subsequent lava flows, many of which poured out of the crater. Within the crater, a depression holds a number of smaller pits, some of which contain active lava ponds.

This view looks west and shows the depression within Pu‘u ‘Ō‘ō Crater. This depression formed following the start of the June 27th lava flow.

A closer look at a glowing hole in the northeast pit in Pu‘u ‘Ō‘ō Crater. Recent overflows from the opening created the dark flows filling the bottom of the pit.

This lava pond was active in the southern pit in Pu‘u ‘Ō‘ō crater. The diameter of the lava pond was roughly 18 m (60 ft). Weak spattering was active on the pond margin.

A closer look at the hole in the northeast pit. An active, bubbling lava surface could be seen a couple meters (yards) below the rim.

After serving as Scientist-in-Charge of the USGS Hawaiian Volcano Observatory for more than 10 years, Jim Kauahikaua, shown here at HVO's Centennial Celebration in 2012, steps aside on March 8, 2015. Kauahikaua will remain on HVO's staff as a research geophysicist, the position he originally held starting in 1988. USGS photo.

The leading tip of the June 27th lava flow remains stalled, but breakouts persist upslope of the stalled tip. Today, one of these breakouts (marked by the arrow) had advanced a short distance towards the north, reaching one of the fire break roads.

This comparison of a normal photograph and a thermal image shows the position of active breakouts relative to the inactive flow tip. The white box shows the rough extent of the thermal image on the right. In the thermal image, active breakouts are visible as white and yellow areas.

This photograph looks east, and shows the breakout on the north flank of Pu‘u ‘Ō‘ō that began over the weekend. The breakout, visible as the lighter colored region in the center of the photograph, occurred from the area of the June 27th vent (upper right portion of photograph).

This large-scale map uses a satellite image acquired in March 2014 (provided by Digital Globe) as a base to show the area around the front of Kīlauea's active East Rift Zone lava flow. The area of the flow on February 19 is shown in pink, while widening and advancement of the flow as of February 23 is shown in red.

This map overlays a georegistered mosaic of thermal images collected during a helicopter overflight of the distal part of Kīlauea's active East Rift Zone lava flow on February 23 at about 12:30 PM. The base image is a satellite image acquired in March 2014 (provided by Digital Globe). The perimeter of the flow at that time is outlined in yellow.
