Questions & Answers

Q: What is the difference between a natural event and a natural hazard?

A natural event refers to a physical process, such as a flood or earthquake, while a natural hazard is a natural event that poses a threat to human systems and people.

Q: How do geographers evaluate hazards?

Geographers evaluate hazards by looking at dimensions such as magnitude, frequency, duration, spatial extent, and spatial concentration.

Q: How do social systems contribute to vulnerability?

Factors such as wealth, education, social organization, and advanced technology can reduce vulnerability to hazards. For example, a strong sense of community can foster social resilience, helping a community recover faster from a disaster.

Q: Why is resilience important in disaster risk management?

Resilience allows a system to absorb shocks and disturbances while maintaining its current functioning and bouncing back from adverse events. Building resilience is an important aspect of disaster preparedness and recovery.
