Developed as part of the Tomorrow's Cities GCRF Urban Disaster Risk Hub project for risk-informed decision making in urban planning. details: 'The dataset includes: (i) earthquake hazard GeoTIFFs for two scenarios - Sc1 using NGA-West2 GMPEs (Abrahamson et al 2014, Boore et al 2014, Campbell & Bozorgnia 2014, Chiou & Youngs 2014) representing active shallow crustal sources, and Sc2 using subduction zone GMPEs (Atkinson & Boore, Zhao et al), each providing PGA and Spectral Acceleration at 0.3s, 0.7s, 1.0s periods in 32-bit and 64-bit precision (48 rasters total); (ii) flood hazard rasters for riverine and pluvial (rainfall) scenarios with water depth as intensity measure, plus NASADEM terrain; (iii) four future exposure dataset variants representing different community planning scenarios, each containing building footprints with structural taxonomy (lateral resistance system, code level, storeys, occupancy), household socio-economic attributes, individual demographic data, land use plans, and road network topology; (iv) fragility functions for earthquake (45 building typologies with 4 damage states) and depth-damage vulnerability functions for flood (495 building typologies at 9 water depths); (v) infrastructure fragility for roads (HAZUS HWB) and power networks (HAZUS ESS); and (vi) impact results for earthquake and flood hazards by community scenario.' exposure: - category: buildings dimension: structure quantity_kind: area, count, currency taxonomy: GED4ALL - category: population dimension: population quantity_kind: count taxonomy: GED4ALL - category: infrastructure dimension: structure quantity_kind: count, length taxonomy: GED4ALL - category: economic_indicator dimension: structure quantity_kind: area taxonomy: GED4ALL extra_attributions: - email: press@ukri.org id: attribution_funder name: Natural Environment Research Council (NERC) role: funder url: https://www.ukri.org/councils/nerc/ - email: servicedesk@ucl.ac.uk id: attribution_collaborator name: University College London role: collaborator url: https://www.ucl.ac.uk/ hazard: calculation_method: simulated disaster_identifiers: '' hazard_analysis_type: deterministic hazard_type: earthquake, flood intensity: PGA:g, wd:m occurrence_range: '' processes: fluvial_flood, ground_motion seasonality: '' license: CC0-1.0 loss: approach: '' base_data_type: '' category: '' description: Affected population results from earthquake impact assessment for each community planning scenario, derived from building damage states and residential occupancy., Affected population results from flood impact assessment for each community planning scenario, derived from building inundation and residential occupancy., Building damage ratio results from flood impact assessment for each community planning scenario (Civil Society, Farmers/Fishermen, Informal Working, Landless).
