A plume rises near active fissures in the crater of Hawaii's Kilauea volcano on Monday, Dec. 21, 2020. People are lining up to try to get a look at the volcano on the Big Island, which erupted last night and spewed ash and steam into the atmosphere. A spokeswoman for Hawaii Volcanoes National Park says the volcanic activity is a risk to people in the park Monday and that caution is needed. (M. Patrick/U.S. Geological Survey via AP)
