One-page overview

This page compresses the PDF into structured revision layers. Every case study is written with the exam logic in mind: location, magnitude, cause, primary effects, secondary effects, and responses.

Volcanoes

Mount St Helens 1980 and Eyjafjallajökull 2010. Focus on eruption style, ash cloud impact, aviation disruption, and response management.

Mt St Helens VEI 5Eyjafjallajökull VEI 4

Earthquakes

Darfield 2010, Christchurch 2011, and Haiti 2010. Compare shallow focus, faulting, ground shaking, liquefaction, and vulnerability.

Christchurch 24bn USDHaiti 222,570 deaths

Landslides

Vargas, Venezuela (1999) and Ponzano, Italy (2017). Learn slope failure triggers, rainfall thresholds, infrastructure failure, and evacuation/monitoring responses.

Case study library

Each card is intentionally dense: the point is to give you the exact exam-ready information in one place. Click through by scanning the headings and tags.

Timeline view

Use the chronological order to memorise the sequence of events and to separate the different case studies in your head.

Flashcards

Tap a card to flip it. Shuffle to test yourself again without memorising the order.

Quiz mode

Choose an option, then reveal the explanation. The questions are built from the PDF facts so they train recognition and recall.

Compare mode

Use this to see patterns: countries with strong governance versus weak governance, high versus low mortality, and the contrast between primary and secondary impacts.

Exam technique and memorisation hooks

These are the fastest ways to turn the case studies into marks: use contrast, specific numbers, and a clear chain from hazard to impact to response.

How to structure a 6- or 8-mark answer

State the hazard, date, and location.
Explain the tectonic or geomorphic setting.
Separate primary effects from secondary effects.
Judge vulnerability: wealth, governance, building codes, population density, preparedness.
Finish with short- and long-term responses and a judgement about effectiveness.

High-value numbers

222,570 deaths in Haiti; 185 deaths in Christchurch; 24 billion USD damage in Christchurch; over 100,000 cancelled flights in Eyjafjallajökull; 1.1 billion USD damage at Mount St Helens; 910 mm in 52 hours at Vargas.

Memory trigger

Think: where did it happen, what was the physical trigger, who was vulnerable, how did the hazard spread, and what was done next.

Memorisation shortcut: for every case study, learn one sentence for setting, one sentence for impacts, one sentence for response, and one judgement sentence on vulnerability or effectiveness.
