Photo & Video Chronology — May 7, 2025 — Kīlauea summit views of the pause after episode 20

By Hawaiian Volcano Observatory May 8, 2025

Episode 20 of the ongoing Halemaʻumaʻu eruption ended after four and a half hours of lava fountaining during the evening of May 6. USGS Hawaiiian Volcano Observatory geologists visited the eruption site on May 7, during the ongoing pause. The rapid rebound of recorded summit tilt from deflation to inflation at the end of episode 20 suggests another episode is likely

A view of north vent of the ongoing eruption within Halema‘uma‘u at Kīlauea volcano, about 12 hours after the end of episode 20. The solidified lava with a smooth silvery appearance in the center of the photo was produced as lava overflowed from north vent. The darker rougher solidified lava on the right formed are "spatter-fed" flows, formed as material from the lava fountain fell onto the rim of north vent, and was hot enough to consolidate and flow. The south vent is partially visible on the left edge of the photo, with a white plume of volcanic gas (mostly water vapor) rising from it. USGS photo by N. Deligne.

On May 7, 2025, about 13 hours after the end of episode 20 of the ongoing eruption at Kīlauea volcano, USGS Hawaiian Volcano Observatory scientists observed a lava ooze-out (center left in image) north of north vent (right side of image). Residual ooze-outs have occurred despite eruptive activity ceasing at the vents, as adjustments and changes in pressure in the molten material beneath the solidified crater floor result in material oozing out. Both the north and south vents are seen degassing in this image on the right side. USGS photo by N. Deligne.

Telephoto view looking into north vent (center) of the ongoing eruption within Halema‘uma‘u at Kīlauea volcano, about 13 hours after the end of episode 20. A conduit approximately 20 meters (66 feet) across is visible inside north vent (center bottom of image), which is approximately 60 meters (197 feet) across. The conduit is approximately 9 meters (30 feet) below the rim of north vent. USGS photo by N. Deligne.

A view looking down on north vent (center) of the ongoing eruption within Halema‘uma‘u at Kīlauea volcano, about 13 hours after the end of episode 20. The south vent is degassing (white vapor rising) on the right side of the photo. From this perspective looking southeast, a conduit approximately 20 meters (66 feet) across is visible inside north vent, which is approximately 60 meters (197feet) across. The conduit is approximately 9 meters (30 feet) below the rim of north vent. Lava flows from episode 20 have a silvery appearance. USGS photo by N. Deligne.
