Tectonic Hazard Management

Managing tectonic hazards presents a unique challenge: unlike weather hazards, earthquakes and volcanic eruptions cannot be prevented, and reliable short-term prediction of earthquakes remains elusive. Effective management therefore relies on a combination of monitoring, prediction (where possible), protection (engineering), preparation (planning and education) and response. This lesson examines each approach in detail, evaluating their effectiveness with reference to specific case studies.

The Management Framework

The AQA specification requires understanding of three overlapping strategies:

    C --> F["Can we build structures<br/>to withstand hazards?"]
    D --> G["Can communities plan<br/>and practise responses?"]

Prediction and Monitoring

Volcanic Eruption Prediction

Volcanic eruptions are significantly more predictable than earthquakes because magma movement produces detectable precursory signals:
