سԹ School of Earth and Environment Senior Lecturer Dr Timothy Stahl is leading new research into how climate change could increase the risk of damage triggered by earthquakes and landslides.
The team is led by Te Whare Wānanga o Waitaha | سԹ (UC) School of Earth and Environment Senior LecturerDr Timothy Stahl, who says earthquakes and landslides are two of Aotearoa New Zealand’s deadliest and most costly natural disasters.
“Cumulatively, landslides have caused more deaths in New سԹthan any other natural hazard and lead to $300 million in insurance claims each year. Our research programme spans geology and disaster risk resilience and provides a better fundamental understanding of these processes.
“We plan to create up-to-date models for these hazards that will ultimately allow us to be more prepared and resilient. We’ll also drive new research into how natural disasters such as landslides, cliff collapse and flooding triggered by earthquakes, are affected by climate change.”
He says this is a high priority area of research because a warming climate and more frequent storms will continue to increase the cost of insurance claims and have a profound impact on people’s lives and property.
“It’s very important because climate change, which is linked to varying storm frequency, intensity and duration, has an impact on several other hazards,” Dr Stahl says.
“If you have more saturated ground prior to an earthquake this increases the risk of earthquake-induced flooding and also means there’s a greater risk of landslides on hillsides.
“Rising sea levels and rivers running higher will also change patterns of earthquake-induced flooding.”
The research team is one of three from the UC recently awarded funding fromto fill knowledge gaps and improve engineering practices. Each programme will receive $450,000 over three years from 2024.
Dr Stahl says the study will expand geological data at key locations along active faults, produce better models of earthquake and landslide multi-hazards, and improve guidance for building near active faults.
“The intended outcome of our research is reduced consequences of earthquake and landslide multi-hazards in a changing climate, as well as training the next generation of hazard and risk specialists to ensure broad capability across Aotearoa New Zealand.”
The programme is based in the Tectonics and Disaster Risk Resilience group at UC. The other members of the team are Senior LecturerDr Tom Robinson,Professor Andy Nicoland Postdoctoral Fellow Dr Camilla Penney, from the UC School of Earth and Environment in the Faculty of Science.
