Hazard Assessment & Evacuation

Science · Volcanoes & Earthquakes · conceptual

Explain probabilistic hazard assessment using eruption recurrence intervals and fault slip rates; describe how volcano observatories monitor ground deformation, gas emissions, and seismicity to issue alert levels; explore why communities remain near active hazards (fertile volcanic soil, poverty, cultural ties); discuss the ethics and politics of evacuation decisions and the social justice dimensions of disaster risk

Check your understanding

If Hazard Assessment & Evacuation read a news story about a town that refused to evacuate before a predicted volcanic eruption, can they describe at least two reasons — beyond just stubbornness — why people might genuinely choose to stay?
