One month ago the summit lava lake was at the rim of the Overlook crater (the small crater in the center of the photo), spilling lava onto the floor of Halema‘uma‘u Crater (the larger crater that fills much of the photo), creating the dark flows surrounding the Overlook crater.

This small-scale map shows Kīlauea's active East Rift Zone lava flow in relation to lower Puna. The area of the flow on May 21 is shown in pink, while widening and advancement of the flow as of June 4 is shown in red.

This map shows recent changes to Kīlauea's active East Rift Zone lava flow field. The area of the flow on May 21 is shown in pink, while widening and advancement of the flow as of June 4 is shown in red. Pu‘u ‘Ō‘ō lava flows erupted prior to June 27, 2014, are shown in gray.

Activity at Pu‘u ‘Ō‘ō remains relatively steady. This photograph looks towards the southwest, and shows outgassing from numerous areas in Pu‘u ‘Ō‘ō crater. On the far side of the crater, the small circular pit (right of center) had a small lava pond that was too deep to see from this angle.

Recent lava on the June 27th flow cascaded over the overhanging rim of this collapse pit on an earlier portion of the flow field.

Scattered breakouts remain active northeast of Pu‘u ‘Ō‘ō. On today's overflight, breakouts were active as far as 8 km (5 miles) northeast of Pu‘u ‘Ō‘ō. Some of this activity was at the forest boundary, burning vegetation.

Halema‘uma‘u Crater, looking west. The dark area on the crater floor consists of recent overflows from the Overlook crater. The Overlook crater is near the left edge of the photo, and a portion of the active lava lake surface can be seen below the rim.

As shown in the May 21 field photos, the small forested cone of Pu‘u Kahauale‘a has been slowly buried by flows over the past several months. All that remains today are narrow portions of the rim standing above the lava.

Earthquakes at Mauna Loa from June 2013 to June 2015. Green circles are 0-5 km (0-3 mi) deep and similar to ones prior to 1975 and 1984 eruptions, but cluster of 5-10 km (3-6 mi) deep quakes missing.

Kīlauea Volcano's summit lava lake dropped from nearly overflowing on April 26, 2015 (left), to about 62 m (203 ft) below the newly created (by multiple overflows) vent rim on May 15, 2015 (right). USGS photos.

This Voyager 1 image mosaic shows a large area of Io's volcanic plains, with numerous volcanic calderas and lava flows. Loki Patera, an active lava lake 1,000 times large than Kīlauea Volcano's summit lava lake, is the black horseshoe-shaped feature in the lower part of the image. Credit: NASA/JPL/USGS

The most distant active tip of the June 27th flow, visible at the left edge of the photo, was about 8.5 km (~5.3 miles) from Pu‘u ‘Ō‘ō today. This lobe of the flow intersected an old lava tube earlier in the week that transported lava a short distance downslope, where it emerged from skylights to make several small isolated pads of lava (center of the photo).

This sequence of HVO webcam images of Kīlauea Volcano's summit vent, recorded between 1:28 and 1:32 p.m., HST, on May 12, 2015, captures the moment a section of the dark-colored "bathtub ring" (a veneer of fresh lava that coats the vent wall as the lava lake level drops) fell into the lava lake (center).
