Why in news
A satellite study by Suhora Technologies revealed the expansion of four out of five high-risk glacial lakes in Arunachal Pradesh's Tawang district over the last decade.
Background
The study analyzed five glacial lakes in the Tawang district of Arunachal Pradesh. Sanhapo Lake was identified as the highest-priority lake for hazard modeling due to its significant expansion and potential for Glacial Lake Outburst Floods (GLOFs).
Facts for Prelims
- PlaceTawang district is located in the state of Arunachal Pradesh.
- S&TGLOF (Glacial Lake Outburst Flood) refers to the sudden release of water from a lake formed by melting glaciers.
