Geologist observing the eruption in Halemaʻumaʻu - June 7, 2023

Detailed Description

A Hawaiian Volcano Observatory scientist makes measurements of the rising active lava lake using a laser rangefinder mid-day on June 7, 2023. These data are used to track the evolving features on the crater floor Halema‘uma‘u, such as the height of the lava fountains, and the geometry of the fissure in the southwest wall of Halema‘uma‘u crater as it built up a spatter cone.
