Coastal Hazards
Know What You’re Scoring Against
A universal hazard framework anchors your assessment in relevance and materiality, localized to your case.
Understanding Universal Coastal Hazards
Three hazard groups engulf the assessment — the risks nearly every coastal city shares — which keeps scores comparable within and alongside other cities.
Geohazard
- Coastal erosion
- Compressible & expansive soil
- Earthquake (shockwave, landslides)
- Landslide (non-seismic)
- Liquefaction
- Sand encroachment
- Subsidence & uplift
Hydrological
- Extreme wave event (e.g., tsunami)
- Marine ecosystem degradation
- Marine pollution (non-point source)
- Marine pollution (point source)
- Sea-level rise (SLR)
- Secondary salinity (incl. saltwater intrusion)
- Urban flooding
- Natural flooding (incl. coastal)
Meteorological
- Extreme coastal event — convective, low-pressure and wind storms (hurricane, typhoon)
- Extreme temperature event — marine cold spell, marine heatwave, ocean rise via warming
