Geological Hazards
Geological hazards is the largest theme under the Natural Hazards Platform. The theme is diverse, covering earthquakes, volcanoes, tsunami and landslides. The overall aim of the theme is a better understanding of the occurrence and processes driving these perils to improve conceptual, numerical and statistical models of each of them. This information can then be used to derive temporal and spatial variation of geological hazards across the country.
The theme is divided into four main projects: one on each of the geological perils. Additionally, it was felt that the production of comparable probabilistic hazard models for each peril warranted the formation of a separate project to bring together all geological hazard modellers. Early activities have involved the assembly of a project team, initial review of existing hazard models, and completion of a major update of the national seismic hazard model.
