IB learning objectives
Geophysical systems
How geological processes give rise to geophysical events of differing type and magnitude
Mechanisms of plate movement including internal heating, convection currents, plumes, subduction and rifting at plate margins
Characteristics of volcanoes (shield, composite and cinder) formed by varying types of volcanic eruption; and associated secondary hazards (pyroclastic flows, lahars, landslides)
Geophysical hazard risks
How geophysical systems generate hazard risks for different places
The distribution of geophysical hazards (volcanoes)
The relevance of hazard magnitude and frequency/recurrence for risk management
Geophysical hazard risk as a product of economic factors (levels of development and technology), social factors (education, gender), demographic factors (population density and structure) and political factors (governance)
Geographic factors affecting geophysical hazard event impacts, including rural/urban location, time of day and degree of isolation
Hazard risk and vulnerability
The varying power of geophysical hazards to affect people in different local contexts
Two contemporary contrasting case studies of volcanic hazards including:
Future resilience and adaptation
Future possibilities for lessening human vulnerability to geophysical hazards
Global geophysical hazard and disaster trends and future projections, including event frequency and population growth estimates
Geophysical hazard adaptation through increased government planning (land use zoning) and personal resilience (increased preparedness, use of insurance and adoption of new technology)
Pre-event management strategies for volcanoes (to include GPS crater monitoring and lava diversions)
Post-event management strategies (rescue, rehabilitation, reconstruction), to include the enhanced use of communications technologies to map hazards/disasters, locate survivors and promote continuing human development

Hazard risk and vulnerability
The varying power of geophysical hazards to affect people in different local contexts
Two contemporary contrasting case studies of volcanic hazards including:
- geophysical hazard event profiles, including any secondary hazards
- varied impacts of these hazards on different aspects of human well-being
- why levels of vulnerability varied both between and within communities, including spatial variations in hazard perception, personal knowledge and preparedness

Watch the video and make notes from page 177 of the Oxford textbook on hotspot volcanoes |
the distribution of volcanoes
Describe the spatial distribution of volcanoes around the planet including the areas of highest concentration. (4)
Using the above image, describe where the most dangerous volcanic areas are (in terms of human deaths).
