October 8, 2021 — Kīlauea summit eruption
In this overflight photo of the Halema‘uma‘u lava lake, captured on October 8, 2021 and looking from the northeast, two western fissures are visible: one inactive from the December 2020–May 2021 Kīlauea summit eruption (center), and another actively feeding lava into the lake at this time (upper-right). The older fissure is is being partially overlapped by short lava flows, but it has not been completely drowned because field measurements show that it is floating within the lake. The presently erupting fissure has formed a horseshoe-shaped spatter cone around its source. USGS image.
