Knowing the likely hazards associated with a future eruption enables us to determine potential impacts. Assigning a probability to these impacts is a way of expressing volcanic risk. To explore this we combine our knowledge of the hazards with information on Auckland’s built and social environment to describe how an eruption would affect Auckland and the rest of New Zealand.
The Auckland Volcanic Field Contingency Plan details the management of an eruption in the field.
A collaboration between the Earthquake Commission and GNS Science, GeoNet provides geological hazard information for New Zealand.
Volcanic ash settling on paved surfaces poses a major safety hazard.
A study of skid resistance on road asphalt and airfield concrete surfaces helps inform recommendations for effective cleaning and road safety maintenance.
A multi-hazard scenario of an Auckland Volcanic Field (AVF) eruption reveals the potential impact on transport infrastructure and network users.
Volcanic ash can play havoc with transport infrastructure, disrupting vital networks.
The degree of disruption depends on particle size and deposit thickness, weather conditions, road surface materials and mitigation actions.
Volcanic ash fall (tephra) can damage or even destroy buildings and infrastructure and threaten health and well-being, along with having a massive impact on both the local and national economy.
A free, multi-hazard risk assessment software programme developed in New Zealand can be a powerful tool for assessing volcanic fields around the world.
