How disrupted will Napier road networks be in the event of a Mw8.4 Hikurangi Subduction earthquake?
GNS scientists have developed a method to predict how our road networks will fare in the face of natural disasters.
The study simulated 10,000 different scenarios showing how a Mw8.4 magnitude earthquake could damage road networks in the city of Napier.
Modelling post-disaster road disruptions
Using detailed data on Napier’s geography, GNS Scientists were able to simulate 10,000 different scenarios showing how an 8.4 magnitude earthquake could damage road networks in the city.
The researchers then analysed how these roadblocks would limit the access of firefighters and ambulance services to different areas, saying that aggregated data from disaster simulations in any city could be used to identify priorities for infrastructure strengthening, and inform decisions about where to locate additional emergency services.
