A part of Nanda Devi glacier broke off in Uttarakhand's Chamoli district on February 7, 2021, striking the Rishiganga Hydroeletric Dam and causing a surge of flood water along the Dhauliganga river. At least seven people were killed, and up to 150 people were missing in flooding after glacier broke off, media quoted the state's Chief Secretary.
