December 21, 2020—Kīlauea summit eruption reference map

The recent eruption at Kīlauea Volcano's summit, within Halema‘uma‘u crater, has generated a lava lake that is being fed by two fissures. Halema‘uma‘u crater has previously been occupied by a water lake (July 2019 to December 2020) and a lava lake (2008 to 2018). The current lava lake is larger than both previous lakes; though it occupies a similar (but larger) location of the former water lake, its location is slightly more north than the former lava lake.  USGS map by M.
