June 24, 2025 — Kīlauea monitoring network fieldwork

USGS Hawaiian Volcano Observatory physical science technicians leave the field after installing two webcams and a continuous laser at the summit of Kīlauea, to help monitor the ongoing lava fountains. The landscape here is now covered by a thick carpet of tephra from the recent lava fountaining episodes, changing much of the appearance of the western caldera rim. In the distance to their left, the vent produces an outgassing plume that hugs the ground and is carried downwind. USGS photo by M. Patrick.
