Enhanced glacial lake activity threatens numerous communities and infrastructure in the Third Pole

T. Zhang, W. Wang, et al.

This groundbreaking research conducted by Taigang Zhang, Weicai Wang, Baosheng An, and Lele Wei investigates the increasing risk of glacial lake outburst floods (GLOFs) in the Third Pole. With accelerated proglacial lake expansion and intensifying events since 1980, their findings reveal that over 6,353 km² of land is at risk, posing threats to communities and infrastructure. Discover the urgency for disaster mitigation strategies in this crucial study!

Abstract

Glacial lake outburst floods (GLOFs) are a significant cryospheric hazard in the Third Pole. This study assesses GLOF risks by combining high-resolution satellite imagery, GLOF modeling, and downstream exposure data. Accelerated proglacial lake expansion drives glacial lake changes. GLOF frequency has increased since 1980, intensifying in Southeastern Tibet and the China-Nepal border. Approximately 6,353 km² of land is at risk, threatening infrastructure and communities. The study highlights the urgent need for disaster mitigation strategies and regional cooperation.
