A helicopter overflight on June 16, 2023, allowed for aerial visual and thermal imagery to be collected of Halema‘uma‘u crater at the summit of Kīlauea. The eruptive activity has consisted of lava fountaining supplying lava flows covering the southwest portion of the crater floor.

This compilation shows a sequence of thermal maps of the ongoing eruption in Halema‘uma‘u crater, at the summit of Kīlauea. The high initial eruption rates in the opening day of the eruption supplied numerous lava fountains that covered the entire crater floor with new lava.

View—looking southwest—of the Kīlauea summit eruption within Halemaʻumaʻu, as captured during a Hawaiian Volcano Observatory helicopter overflight the morning of June 16, 2023. Lava can be seen erupting from a vent on the southwest crater wall in the background.

View from the southern rim of Halemaʻumaʻu crater at the summit of Kīlauea on Friday, June 16, 2023, showing the southwest eruptive vent that is currently spattering and feeding lava flows on the crater floor. The fountaining is continuous, with lava bombs being thrown at least 10 m (33 ft) upwards and at least twice that distance away from the vent.

This reference map depicts the Kīlauea summit eruption on June 14, 2023. The provided eruption statistics are derived from helicopter overflight data collected on Monday, June 12, but map features have been updated based on Wednesday, June 14 webcam views.

An overview of eruptive activity in Halemaʻumaʻu crater at the summit of Kīlauea during the evening of Wednesday, June 14, 2023. The eruptive vent in the southwest wall of the crater (right) appeared to be the only active vent, and it was supplying lava into a lake in the southwestern portion of the crater. USGS photo by M. Patrick.

On June 12, 2023, HVO scientists conducted an overflight of the eruption within Halemaʻumaʻu crater at the summit of Kīlauea volcano. This aerial photo shows the darker parts of the crater floor, most which have been covered with new lava since the eruption began on June 7.

The island, which was created in the very first hours of the 2020 Halema‘uma‘u lava lake eruption, is still visible. Fresh lava from the opening of the 2023 eruption has risen high around the edges and covered part of the surface. Hawaiian Volcano Observatory geologists wonder how much longer this feature will survive. USGS photo by J. Schmith.

This compilation shows thermal maps of the initial days of the ongoing eruption in Halema‘uma‘u crater, at the summit of Kīlauea. The high initial eruption rates in the opening day of the eruption supplied numerous lava fountains that covered the entire crater floor with new lava.

In this telephoto view of the eruption within Halema‘uma‘u crater, lava flows from right to left from an outlet in lower right side of photo. As lava flows, the outlet slowly grows a soft crust of dark lava fingers. USGS photo by J. Schmith on June 12, 2023.

From the southwest part of Halema‘uma‘u crater rim, Hawaiian Volcano Observatory geologists were able to view into vent perched on the western wall. On June 12, they observed that lava was still spattering inside the vent, but rarely making it out of the top. USGS photo by J. Schmith.
