Hazard vulnerability risk assessment
Hazard vulnerability risk assessment
 
 
 

Through hazard vulnerability risk assessments, we characterise the diversity of hazards and subsequent risks affecting communities whether it be at regional or local scale. Our assessments combine the use of field-based investigation and mapping, high resolution remote sensing, analysis of past events, and modelling of current and future scenarios.

The output of our assessments are then used to analyse risk prioritisation, construct hazard, risk and vulnerability maps, and design mitigation and prevention measures, such as early warning systems.

 
 

Oblique view from one of our multi-hazard risk assessment projects located in the province of Badakhshan, Afghanistan. This example shows active landslide areas (in yellow) and catchments with debris flow/flash flood activity (blue valley segments) overlain in a google earth image. Risk maps were created by identifying settlements affected by various modelled hazard scenarios.

 
 

Image showing several valleys with settlements, represented as white points, where glacial lakes, mapped with high resolution satellite imagery were identified. Qualitative runout potential was evaluated for GLOF lakes at regional scale. The coloured lines indicate downstream paths for three different runout distance classes (adapted from published literature). Note these are not modelled runout distances for discrete GLOF events.
