Enquiry question 3: How successful is the management of tectonic
hazards and disasters?
Tectonic mega-disasters can have regional or even global
significance in terms of economic and human impacts.

The concept of a multiple-hazard zone and how linked
hydrometeorological hazards sometimes contribute to a
tectonic disaster ( the Philippines).
what is a multiple hazard area?
what is a hydrometeorological hazard?
Tectonic disaster trends since 1960 (number of deaths,
numbers affected, level of economic damage) in the context
of overall disaster trends. (6); research into the accuracy and
reliability of the data to interpret complex trends

The importance of different stages in the hazard management
cycle (response, recovery, mitigation, preparedness).

Strategies to modify vulnerability and resilience include
hi-tech monitoring, prediction, education, community
preparedness and adaptation. (F: models forecasting
disaster impacts with and without modification)
Strategies to modify the event include land-use zoning,
hazard – resistant design and engineering defences as well as
diversion of lava flows. (P: role of planners, engineers)

Strategies to modify loss include emergency, short- and
