Supraglacial lake outburst in Tibet caused Bhotekoshi flooding

Reports by hydrology department and ICIMOD say satellite image analysis of a glacial lake upstream confirms it caused Tuesday’s flooding.

An outburst of a previously unnoticed supraglacial lake formed in Tibet above the Rasuwagadhi border point is responsible for Tuesday’s devastating flood on the Bhotekoshi river, according to two separate reports by the Department of Hydrology and Meteorology and the International Centre for Integrated Mountain Development (ICIMOD).
