All roads lead to disruption following volcanic eruption

A multi-hazard scenario of an Auckland Volcanic Field (AVF) eruption reveals the potential impact on transport infrastructure and network users.

The metrics developed to assess transportation network damage and functionality can also be applied elsewhere in the world.

In the Auckland scenario, most of the transport network damage follows early volcanic surges. However, much of the network service disruption is caused by large-scale evacuation in the six days prior to eruption.

Up to 435,000 residents and many businesses may be displaced.

Ash on road and rail following an eruption also affects transport services for several months.

Community uncertainty over further activity can prompt greater residential movement.

The scenario highlights the importance of transport planning when developing volcanic impact and risk assessments. Service metrics must cover road, rail, airports and ports.
