Close-up view of active western fissure in Halema‘uma‘u, February 12,

This close-up view of the active western fissure in Halema‘uma‘u was captured through the lens of a laser rangefinder device, used by HVO scientists to measure distances to features within the crater. Lava is flowing into the lake at a bubble-like inlet near the base of the spatter cone that has been formed by the fissure. The cone was measured to be approximately 30 m (98 ft) tall.
