IB Objectives:
Part 1: Geophysical systems
Characteristics of earthquakes (depth of focus, epicentreand wave types) caused by varying types of plate margin movement and human triggers (dam building, resource extraction); and associated secondary hazards (tsunami, landslides, liquefaction, transverse faults)
Part 2: Geophysical hazard risks
Part 1: Geophysical systems
Characteristics of earthquakes (depth of focus, epicentreand wave types) caused by varying types of plate margin movement and human triggers (dam building, resource extraction); and associated secondary hazards (tsunami, landslides, liquefaction, transverse faults)
Part 2: Geophysical hazard risks
- The distribution of earthquakes
- Hazard magnitude and frequency
- Earthquake hazard risk – including levels of development and technology, social factors (education, gender), demographic factors (population density and structure) and political factors (governance)
- Geographic factors affecting earthquake hazard event impacts, including rural/urban location, time of day and degree of isolation
- 2 contrasting earthquake case studies. Including the following:
- Geophysical hazard event profiles, including any secondary hazards
- Varied impacts of these hazards on different aspects of human well- being
- Why levels of vulnerability vary both between and within communities, including spatial variations in hazard perception, personal knowledge and preparedness
- Global earthquake 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 earthquakes and tsunami - to include building design, tsunami defences
- 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

2 x EARTHQUAKE CASE STUDIES
Required are two earthquake case studies of a similar magnitude
| earthquake_case_studies.docx |
earthquake case study 1 (lic): The Haiti Earthquake, 2010

| haitiearthquakeimpacts.pdf |
The areas it should cover in the Haiti case study are:
-What are the physical reasons that Haiti is vulnerable to the impacts of earthquakes?
- What were the primary hazards and the secondary hazards of the Haiti earthquake?
- How the the location of the focus of Haiti's earthquake contribute to the extent of the damage?
-How did Haiti's economy contribute to the extent of the damage?
- What were the main priorities in the immediate rescue phase, and how did these differ from the later rehabilitation and recovery phase?
- What aspects of the post-earthquake operation in Haiti could have been improved to advance human well- being?
-What are the physical reasons that Haiti is vulnerable to the impacts of earthquakes?
- What were the primary hazards and the secondary hazards of the Haiti earthquake?
- How the the location of the focus of Haiti's earthquake contribute to the extent of the damage?
-How did Haiti's economy contribute to the extent of the damage?
- What were the main priorities in the immediate rescue phase, and how did these differ from the later rehabilitation and recovery phase?
- What aspects of the post-earthquake operation in Haiti could have been improved to advance human well- being?

Complete the hazard profile for the Haiti and Mexico city earthquakes
example exam questions
Discuss the importance of hazard profiles in terms of both the assessment of hazard severity as well as its application for hazard management (10)
Assess the reasons why vulnerability of communities to geophysical hazards vary in contrasting places of the world. (10)
Discuss the extent to which you agree with the statement 'that risks that communities are exposed to from geophysical hazards depends almost entirely on the magnitude of the event'. (10)
