March 4, 2022—Kīlauea summit eruption reference map

This reference map depicts the ongoing Kīlauea summit eruption on March 4, 2022. One eruptive vent is intermittently active within Halema‘uma‘u, in the western end of the crater. When this vent is effusing lava, it pours into a lava lake, colored red on this map. During eruptive pauses, the only active lava is within a pond just north of the vent, colored dark purple on this map. The eruption statistics provided here are current as of the last HVO overflight on March 2, 2022; the volume-averaged surface of the whole lava lake was approximately 2,726 ft (831 m) above sea level at that time. When the eruption is vigorous, lava is visible from three public visitor overlooks in Hawai‘i Volcanoes National Park: Keanakāko‘i Overlook and KUPINAI Pali (Waldron Ledge) can see the eruptive vent and lava lake, while Kīlauea Overlook can occasionally see lava ooze-outs in the southeast part of the crater.
