A large ash plume rose from the Halemaumau Crater of Hawaii’s Kilauea volcano on May 15, as seen in this footage.The ash plume rose between 10,000 to 12,000 feet above sea level at its peak, the United States Geological Survey (USGS) reported. The plume prompted USGC to raise their alert from an orange to red warning, meaning: “Major volcanic eruption is imminent, underway, or suspected with hazardous activity both on the ground and in the air.” Credit: Kimberly Bishop via Storyful
