Spatial Influences on Hazard Severity

How Location, Time, and Isolation Shape Hazard Impacts

1. Location: Urban vs. Rural Areas

Urban Areas

High Population Density: More people in smaller spaces increases the risk of casualties.
Infrastructure Collapse: Skyscrapers, bridges, and roads amplify destruction.
Economic Losses: Damage to businesses and infrastructure has long-term impacts.

Example

The 2010 Haiti earthquake devastated Port-au-Prince, where poorly constructed buildings collapsed, causing widespread casualties.

Rural Areas

Fewer Immediate Casualties: Lower population density often means fewer deaths.
Delayed Emergency Response: Isolation can hinder rescue efforts.
