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.
Several eruption scenarios set the scene for developing better volcanic risk mitigation and asset management practices.
Observations and numerical models can help explore the depositional mechanisms, macroscale current dynamics, and potential impact on the city of dilute pyroclastic density currents (PDCs) in the Auckland Volcanic Field (AVF).

A detailed study of the ancient and modern topography of New Zealand’s most populous city, Auckland, has revealed significant concealed fault offsets beneath the region’s volcanic field deposits.

The scale of eruption in the Auckland Volcanic Field (AVF) appears to be controlled by the dynamics of the soft area (asthenosphere) of the upper mantle.
The orientation of horizontal components of borehole seismometers is unknown on installation.
However, it is crucial to any multicomponent seismic analysis.
The rate of activity in the Auckland Volcanic Field (AVF) in the upper North Island of New Zealand has been increasing for the past 60,000 years, suggesting that the field is still in its infancy.
