Heavy rains in recent weeks resulted in water accumulating in the case of the KWcam, a webcam monitoring the summit of Kīlauea. HVO staff visited the site today to replace desiccant and dry out the enclosure. USGS photo by M. Patrick.

Weak, wispy gas plumes rise vertically in the slack winds from the central portion of Halema‘uma‘u, at the summit of Kīlauea. Nothing unusual was observed today at the summit. USGS photo by M. Patrick.

During the March 21, 2024 lahar evacuation drills, thousands of students walked to the Washington State Fairgrounds in Puyallup, Washington to practice evacuating from a lahar generated by Mount Rainier. A lahar, or volcanic mudflow, could reach this area in about 3 hours.

HVO geologists made a routine visit to check on equipment at the summit of Kīlauea today, and had clear views across the floor of Halema‘uma‘u. The central portion of this photo is the region where much of the lava lake activity has occurred over the previous few years, with the area now showing only wispy plumes of weak gas emission.

This photo shows the eastern portion of Halema‘uma‘u, at the summit of Kīlauea. The circular area of yellow coloration, near the top of the photo, is spot where the first lava fountain emerged in the September 2023 eruption. In the lower portion of the photo, the remains of Crater Rim Drive and the Halema‘uma‘u parking lot are visible.

HVO geologists observed the new eruption within Kīlauea summit caldera during an eruption-monitoring overflight the morning of September 11, 2023. Multiple minor fountains remain active in the eastern portion of Halema‘uma‘u crater floor and on the downdropped block within Kīlauea's summit caldera.
