Hawaiian Volcano Observatory images of eruptive activity, field work, and more.
This photo was captured during the July 2 mission to the northwest side of Halema‘uma‘u crater, which was done with permission from and coordination with Hawai‘i Volcanoes National Park. The two USGS Hawaiian Volcano Observatory scientists pictured here are collecting tephra from a deposit exposed in the northwest crater wall.

Displacement field showing the horizontal (red arrows) and vertical (blue arrows) components of motion recorded by Global Positioning System (GPS) positions at each campaign benchmark site from surveys conducted between 2025-2026. The arrows point in the direction of motion and lengths represent how far positions were displaced over the past year.

View looking down the north vent, taken during a USGS Hawaiian Volcano Observatory monitoring overflight on June 30, 2026. Glow and flames have been intermittently seen since episode 50 of lava fountaining in Halema‘uma‘u ended on June 27, 2026, but no glow was observed from the north or south vents during the overflight.

Photo compilation of lava fountaining episodes 1–50 in the ongoing eruption at the summit of Kīlauea, including webcam imagery and photos taken by USGS Hawaiian Volcano Observatory scientists on the ground and during helicopter overflights. In all photos except for episode 7, the south vent is on the left and the north vent is on the right.

Aerial photograph taken during a USGS Hawaiian Volcano Observatory monitoring overflight on June 30, 2026, looking to the east across lava flows that have accumulated in Halema‘uma‘u during the 50 lava fountaining episodes that have occurred since December 23, 2024. The black lava flows are rubbly ʻaʻā lava flows and the shiny, gray, smooth lava flows are pāhoehoe.

Aerial photograph taken during a USGS Hawaiian Volcano Observatory monitoring overflight on June 30, 2026, to characterize the tephra and lava flows from Kīlauea summit fountaining episode 50 that occurred on June 27, 2026. The north and south vents have a robust plume coming from them with fresh black and gray lava flows covering much of Halema‘uma‘u crater floor.

While visiting the closed area of Hawai‘i Volcanoes National Park, USGS Hawaiian Volcano Observatory scientists found volcanic bombs (fragments that are larger than 2.5 inches or 64 mm) that were deposited during Kīlauea summit eruption lava fountaining episode 50, which were strewn across the tephra cone on the southwest side of Halema‘uma‘u crater.

This reference map depicts the Kīlauea summit eruption within Halema‘uma‘u crater that began on December 23, 2024. Most of the data for this map were collected during a Hawaiian Volcano Observatory helicopter overflight on June 9, 2026. As such, the provided statistics are reflective of the first forty-eight episodes of the eruption through June 1, 2026.

Along the south portion of Halemaʻumaʻu crater, a portion of Crater Rim Drive that fell into the crater during the 2018 Kīlauea summit collapse is close to being covered with lava flows. The block that the road is located on is tilted, allowing lava flows to traverse up it like a ramp from the lower left part of the photo.
