This reference map depicts the fissure and lava flows from the Kīlauea middle East Rift Zone eruption of Sunday, September 15, 2024. The eruption occurred between approximately 9:00 and 10:00 p.m., in a remote and closed area of Hawaiʻi Volcanoes National Park. This map was constructed from data collected during a Hawaiian Volcano Observatory overflight the following morning, Monday, September 16. Geologists observed two lava pads covering 16,500 square meters (4 acres) that had erupted from a 480-meter (1600-foot) long fissure, which was eruptively inactive but still emitting volcanic gases at the time of the flight.
