A glacial lake outburst flood in Bhutan’s Gasa district damaged roads and a bridge and prompted high alerts in Assam, India, on 29 October. Earlier, the sudden release of water from Shintaphu Lake led Indian authorities to issue flood advisories for districts in West Bengal and Assam and to monitor the Sankosh River. The flood also forced the evacuation of more than 10,000 residents in West Bengal and saw disaster response teams from the National Disaster Response Force and state forces deployed to the affected areas.

    It’s always the communities downstream who bear the brunt when these sudden disasters hit, often with little warning or support. I wonder how well-equipped local authorities really are to protect people whose homes and livelihoods can be wiped out in a flash like this.
