The summit lava lake in Halema‘uma‘u Crater was at a high level earlier in the week, and partly visible from the Jaggar Museum Overlook at times. But over the past few days, the lake level has dropped slightly.

The two new flows that broke out on the flanks of the Pu‘u ‘Ō‘ō cone on Kīlauea Volcano's East Rift Zone on May 24 remained active early this morning. The flows were spreading laterally near the vent, but making little forward progress; as a result, they were not posing a threat to any community.

The second flow from the eastern breakout on Pu‘u ‘Ō‘ō—in the area of the "Peace Day" flow that broke out in September 2011—remained active as of this morning, and its total length was about 1.2 km (0.75 mi) long. This lava flow was slowly spreading laterally, but the flow front had stalled.

Amidst steam created by rain falling on the hot lava, another HVO geologist uses a rock hammer to collect a sample of the active flow. Analyses of this sample will yield data on the temperature and chemical makeup of the lava, information that is needed to help determine what's happening within the volcano.

As of 8:30 a.m., HST, today, May 25, 2016, lava continued to flow from two breakout sites on the flanks of the Pu‘u ‘Ō‘ō cone, which was shrouded by rain and steam during HVO's morning overflight.

This small-scale map shows Kīlauea's active East Rift Zone lava flow field in relation to the eastern part of the Island of Hawai‘i. The new breakouts from Pu‘u ‘Ō‘ō that began on May 24 are shown in red, as mapped on May 25. The area of the original June 27th lava flow field is shown in pink, as last mapped in detail on May 9.

This morning (May 25, 2016), the northern breakout on Pu‘u ‘Ō‘ō was feeding an impressive channel of lava that extended about 950 m (0.6 mi) northwest of the cone. This channel was about 10 m (32 ft) wide as of 8:30 a.m., HST.

Despite heavy rain, which resulted in blurry spots on this photo due to water droplets on the camera lens, HVO scientists were able to do some of the work they hoped to accomplish during this morning's overflight. Here, an HVO geologist maps the location of active lava from the eastern breakout on Pu‘u ‘Ō‘ō.

The two breakouts that began at Pu‘u ‘Ō‘ō yesterday (May 24) are still active. This morning, the active portions of both flows remained relatively short, extending no more than 1 km (0.6 miles) from their breakout points.

Two new breakouts at Pu‘u ‘Ō‘ō began this morning just before 7:00 a.m., HST. The larger of the two breakouts, shown here, originated on the northeast flank of the cone, at the site of the vent for the ongoing June 27th lava flow. This breakout point fed a vigorous channelized flow that extended about 1 km (0.6 miles).

Another breakout occurred just east of Pu‘u ‘Ō‘ō, about 500 m (0.3 miles) from the crater, in the area of the "Peace Day" flow that broke out in September 2011. This second breakout was smaller than the one on the northeast flank, but was still feeding an impressive lava channel.
