About natural hazards notes
GoConqr OriginalUsing natural hazards notes
These notes range from definitions to case studies. Global Hazards Definitions is a useful starting point if you want to review terms. For an introduction to one hazard, try The Geography Of Earthquakes, which explains earthquakes and seismic waves.
When you are ready for examples, the collection includes notes on the Christchurch earthquake and Hurricane Jeanne in Haiti. There are also Volcanic eruptions case studies and notes on the Indian Ocean tsunami. Other resources look at disaster hotspots in the Philippines and the impact of climate change on Africa.
Revise with notes
Read a case study and make a short summary of its causes and effects. Then use Comparing Earthquake Effects in MEDCs and LEDCs to consider differences between places. Return to the definitions if a term is unfamiliar.
For a different way to review a topic, switch to a mind map on the Natural Hazards unit page. A quiz can help you check what you remember afterwards. Choose a set of notes and start with a topic you want to revisit.
Frequently asked questions
Which notes should I start with?
Start with Global Hazards Definitions if you want to review terms, or The Geography Of Earthquakes for an introduction to earthquakes and seismic waves. You can then move on to the earthquake case studies or the notes on Christchurch to see how an individual event is described.
What case studies do the notes cover?
The collection includes notes on Hurricane Jeanne in Haiti, the Christchurch earthquake and the Indian Ocean tsunami. Volcanic eruptions case studies offers another route into examples. There are also notes on disaster hotspots in the Philippines and the impact of climate change on Africa.
