The lava lake within the Overlook crater in Halema‘uma‘u, at Kīlauea volcano, continues to rise. It was measured at 12 m (~39 ft) below the floor of Halema‘uma‘u at about 8 AM this morning, when this photo was taken.

This grainy evening photo shows the lake at 6:30 PM, when it was a mere 7 m (23 ft) below the Halema‘uma‘u Crater floor.

This photo, taken at mid-day, shows the lava lake as seen from the west side of Halema‘uma‘u, which offers a different perspective. The lava lake was about 10 m (33 ft) below the floor of Halema‘uma‘u at this time.

Preview image for video: The lava lake in the Overlook Crater, within Halema‘uma‘u Crater at the summit of Kīlauea Volcano, has been rising over the past few days. Today the lava was as high as 14 meters (46 feet) below the Overlook crater rim. Several areas of spattering were active along the lake margin.

The level of the lava lake within the Overlook crater, set within Halema‘uma‘u Crater at the summit of Kīlauea Volcano, continues to rise. Today, the level was as high as 14 meters (46 feet) below the Overlook crater rim.

This map shows recent changes to Kīlauea's active East Rift Zone lava flow field. The area of the flow on April 9 is shown in pink, while widening and advancement of the flow as of April 23 is shown in red. Pu‘u ‘Ō‘ō lava flows erupted prior to June 27, 2014, are shown in gray.

Breakouts on the June 27th lava flow remain active northeast of Pu‘u ‘Ō‘ō. A new, small, breakout appeared recently from the tube adjacent to Pu‘u Kahauale‘a, the small forested cone near the center of the photograph. The new breakout is the light-colored curved flow in the left portion of the photograph. Pu‘u ‘Ō‘ō is in the upper right portion of the photo.

The farthest active breakout on the June 27th flow reached about 8 km (5 miles) northeast of the vent on Pu‘u ‘Ō‘ō. The tip of this breakout was narrow and burning forest. Pu‘u ‘Ō‘ō is at the top of the photograph.

A small breakout from an inflated portion of the June 27th flow. Large gas bubbles reach the surface near the source of the breakout, and are then carried and deformed as the surface advances and cools.

The June 27th flow covers much of the top of the photograph, and recent expansion of the flow margins has sent lava cascading into one of the ponds on the 2007 perched lava channel. This 2007 lava fills the bottom of the photograph, and is covered with yellow alteration.

Over the past week small flows have filled the bottom of Pu‘u ‘Ō‘ō Crater. These flows originated from vents in the south portion of the crater, and one of the flows can be seen near the center of the photograph.

The Overlook crater lava lake, within Halema‘uma‘u Crater at Kīlauea's summit, has been rising over the past few days, and today reached the highest point yet measured for the current summit eruption. The lava lake this afternoon was 20 meters (66 feet) below the Overlook crater rim.

Another view of the lava lake, with several areas of spattering active.

The lava level was high enough at the lava lake this evening that bits of spatter were reaching the rim of the Overlook crater.

This satellite image was captured on Monday, April 20, 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.

Active surface flows on the northeast flank of Pu‘u ‘Ō‘ō on March 12, 2015. The activity is a continuation of a breakout that began on February 21, which diverted lava from the tube system and helped to starve the supply of lava to the June 27th flow front near Pāhoa.
