Kathmandu Valley Single Hazards and Multi-Hazard Interrelationships Database

This Kathmandu Valley Single Hazards and Multi-Hazard Interrelationships Database uses a systematic review of blended evidence types (academic literature, grey literature, media, databases, and social media) to compile single hazard and multi-hazard interrelationship exemplars of natural hazards in the context of Kathmandu Valley.We identify 58 sources of evidence for single hazard types and 21 sources of evidence for multi-hazard interrelationships. These sources evidence 21 single hazard types across six hazard groups, and 83 multi-hazard interrelationships that could influence Kathmandu Valley. Of these multi-hazard interrelationships, 12 have direct case study evidence of previous influence in Kathmandu Valley.This Excel database accompanies the paper Thompson et al. (2024).The Kathmandu Valley Single Hazards and Multi-Hazard Interrelationships Database comprises the following sheets:          A. Single Hazards Evidence            B. Hazard Interrelationships Evidence            C. Hazard Interrelationships Matrix            D. Matrix Evidence            E. Definitions (Source Types)            F.

References  In Sheet A, each row in the database describes a separate source of evidence of a single hazard influencing Kathmandu Valley. In each column, we describe the evidence using the qualifiers outlined below:Hazard typeSource information and linkSource contentHazard interrelationships and anthropogenic processesVideo evidenceSource reflectionsMajor event typical frequency reflectionAny other reflection on a single hazardImpactIn Sheet B, each row in the database describes a separate source of evidence of a multi-hazard interrelationship influencing Kathmandu Valley. In each column, we describe the evidence using the qualifiers outlined below:Hazard typeSource information and linkSource contentHazard sequenceSource reflectionsImpactInput from practitioner stakeholdersInput from practitioner stakeholders - prioritisationWe refer the reader to Thompson et al.
