🏔️ GLOF WATCH Glacial lake outburst flood risk · today & 2050/2100 · free

Will a glacial lake
flood your valley — today, or by 2100?

A 2026 simulation projected potential glacial-lake outburst floods (GLOF) for over a thousand basins worldwide, under three warming scenarios. No public tool lets you search it by place — until now.

What these scores mean

Each basin carries four scores (1–5) from the source simulation: Hazard (physical likelihood/severity of an outburst), Vulnerability (how exposed the terrain is), Exposure (people/infrastructure in the flood path) and Risk (the combined verdict). The map shows the simulated flood extent polygon for the scenario selected — the same shape the source paper computed hydraulically, not a buffer or an estimate drawn after the fact.

Limits, stated first. Resolution is per-basin, not per-village: the score applies to the whole simulated catchment, and distance to the basin centroid is shown above. The simulation is a 2026 projection under SSP climate scenarios, not a forecast of a specific date or a warning of an imminent event — it does not model sudden ice-dam collapses or earthquake-triggered events outside its own hydraulic model. Coverage concentrates on basins with an active glacier feeding a lake; many inhabited valleys near glaciers are not in this dataset at all, and a "no data" address does not mean zero risk.
