Regional Hazards

The Civil Defence Emergency Management Group is required to consider any and all hazards that may lead to a declaration of a state of local emergency. These hazards must be of significant enough to be beyond the ability of emergency services to cope.

The most likely hazards of the Bay of Plenty region to reach this threshold are the major natural hazards:

  • Volcanic eruption or a threatening eruption from any one of the volcanic centres of the region, or adjacent to the region.
  • Earthquakes of high-magnitude which can occur within any of the seismic (earthquake) fault belts of the region, or from sources adjacent to the region.
  • Flooding or other storm-related damage throughout the region.
  • Tsunami impact on the coastline of the region.

It is possible that other, technological (human-made) hazards could also cause major damage to parts of the region.

Such impacts could be generated by:

  • Failure of a hydro, water storage or natural dam
  • Explosion of a large fuel storage or industrial facility
  • Fire in a toxic chemicals storage or manufacturing area, possibly including a bulk carrier of one kind or another, leading to high-volume gas release
  • Catastrophic transport accident, including an aircraft crash within an urban area.
