November 4, 2021—Kīlauea summit eruption reference map

November 4, 2021


Color map of lava lake at volcano summit
This reference map depicts the ongoing Kīlauea summit eruption on November 4, 2021. One eruptive vent is active within Halema‘uma‘u at this time, along the western edge of the rising lava lake. Similar to the last eruption—from December 2020 until May 2021—the eastern end of the lava lake has stagnated and solidified, and sits several yards (meters) lower than the actively circulating western end. Still, lava ooze-outs from the northeast edge of the lake have started to lap onto the lowest remaining down-dropped block from the 2018 collapse event within the summit caldera. Note that this map depicts contour elevations in feet, with the surface of the active lava lake now at approximately 2,618 ft (798 m) above sea level. At this time, active lava is visible from two public visitor overlooks in Hawai‘i Volcanoes National Park: a site along the trail between Kīlauea Overlook and Uēkahuna can see the southeastern edge of the lava lake, and a section of the Keanakāko‘i Overlook can see the eruptive vent.
