Satellite assessment shows 73% reduction in Bhutan’s lake after GLOF
A satellite assessment reveals that Bhutan's Sintaphu Tsho glacial lake experienced a 73% reduction in surface area following a glacial lake outburst flood (GLOF) in late October. The study, conducted by Suhora Technologies, highlights the significant environmental impact of the event on the Himalayan landscape.
Why it matters
GLOFs pose a severe threat to downstream communities and infrastructure, making real-time satellite monitoring essential for disaster mitigation and climate change adaptation.
GUWAHATI An almost real-time satellite-based assessment of the impact of the glacial lake outburst flood (GLOF) in Bhutan’s Gasa district on October 29 has revealed a 73% reduction in the surface area of Sintaphu Tsho, the affected Himalayan glacial lake. The assessment by Suhora Technologies, a Noida-based geospatial intelligence company, also shows a 24.4% reduction in the surface area of a supraglacial lake adjoining Sintaphu Tsho. A supraglacial lake is a temporary body of meltwater that collects in surface depressions on a glacier or ice sheet.
