October 20, 2021—Kīlauea summit eruption reference map

This reference map depicts the ongoing Kīlauea summit eruption on October 20, 2021. Only 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 still-active western end. Note that this map depicts contour elevations in feet, with the surface of the active lava lake now at approximately 2,598 ft (792 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 fountains at the eruptive vent.
