New paper today in @science.org focused on unraveling the chain of events that led to the 2023 Teesta disaster, which resulted in about 130 people either dead or missing in Sikkim, India. Short thread to follow. 🧪⚒️ doi.org/10.1126/scie...

Our new paper in Science (Sattar et al 2025) analyses the causes, process and impacts of the 3-4 October 2023 landslide-triggered GLOF along the Teesta River in Northern India. This was an amazing event - I've provided a summary of the research on the Landslide Blog:- eos.org/thelandslide...
