Abstract:
The physical, tectonic, environmental and climatological settings and anthropogenic activities coupled with the climate change in northern Pakistan, provide an ideal landscape for the frequent and damaging multi-hazards mainly landslides, debris flows, GLOF and earthquakes. However, given the complex terrains and data-poor region, comprehensive multi-hazard, vulnerability and risk assessment are rarely available for effective disaster management. Methodologies are developed to utilize the available data, techniques and models for regional-scale landslide, debris flow, GLOF and seismic hazards and risk assessments. Manual and semi-automatic techniques are applied to develop multi-hazard inventories that are related to the physical and environmental settings; and potential triggers to acquire the susceptibility and hazard assessments. The elements at-risk database comprising the settlement’s footprints, typological information, communication network, land use, critical infrastructure, and social vulnerability indicators are utilized for vulnerability and eventually risk analysis. The morphometric analysis of the drainage basins and statistical models are useful for investigating the watershed susceptible to debris flows and for applying local scale simulation models. The element-at-risk features on the alluvial fan of the respective watersheds are analyzed for their exposure, vulnerability and risk analysis. Seismic site characterization maps are produced through field-based measurements of the shear wave velocities and relevant proxies such as the geology and terrain slope. The GLOF hazard and risk are accomplished for the high-risk glacial lakes. The integrated multi-hazard is analyzed with the element at-risk databases for the multi-hazard vulnerability and risk assessment. Considering the unprecedented devastation caused by the intense monsoon in 2022, dynamic and quantitative risk assessment and adaption/mitigation planning are critical for disaster risk reduction and therefore offer opportunities for collaboration for joint research studies on climate change impacts on dynamic multi-hazard risk assessment in the region.
