Hawaii’s Kīlauea volcano on the Big Island entered a new, intense eruptive phase early Monday, according to the U.S. Geological Survey. Episode 48 of the Halemaʻumaʻu eruption began at 4:40 a.m. HST after a series of overflow events over the weekend. Lava fountains at the summit have exceeded 650 feet, with plumes rising to about 24,000 feet above sea level. Tephra, including pumice and Pele’s hair, has fallen across Hawaiʻi Volcanoes National Park and nearby communities, affecting Highway 11 and residential areas. USGS has set an Orange aviation code and Watch alert, warning of ongoing seismic, air quality, and physical hazards.
