    • GeoNet’s Shaking Layer Tool: Generation of near-real time ground shaking for post-event response 

      Horspool, Nick; Goded, Tatiana; Kaiser, Anna; Chadwick, Mark; Charlton, Danielle; Houltham, Jeremy; Groom, Josh (2023-04-19)
      Information on ground shaking following an earthquake is important for many applications from emergency response, engineering assessments, infrastructure management, insurance claim estimation and research. GeoNet, along ...

    • Risk thresholds in the built environment 

      Dunne, Caleb; Saunders, Wendy (2023-04-19)
      Engineering and building design inherently deal with risk. But risk is rarely—if ever—explicitly considered. Most building design in Aotearoa New Zealand (i.e., to B1/VM1 NZS1170) targets an annual individual fatality risk ...

    • Seismic hazard analysis for a bridge across Marikina River with consideration of near-fault effects 

      Selda, Patrick Adrian; Bernales, Francis Jenner; Quebral, Ramon; Luna, Roy Anthony (2023-04-19)
      The Valley Fault System in Metro Manila, Philippines is widely considered to be an impending threat in releasing a large-scale earthquake. Such earthquake is forecasted to impose severe casualties and economic losses to ...

    • Simplified approach to rapidly predict road blockages caused by co-seismic landslides 

      Lin, Amelia; Wotherspoon, Liam; Zorn, Conrad (2023-04-19)
      The 2016 Kaikōura earthquake triggered tens of thousands of landslides leading to several road blockages which isolated the population in Kaikōura and disrupted the transport services across the South Island. The prediction ...

    • Site-specific seismic hazard analysis - evolving developments in practice 

      Orchard, Stuart; Taylor, Merrick; Jury, Rob; Berryman, Kelvin (2023-04-19)
      Site-specific hazard analyses (SSHAs) are undertaken to inform seismic actions for the design of important projects in New Zealand. These have typically adopted the 2010 National Seismic Hazard Model (NSHM) as the reference ...

    • Site-specific seismic hazard evaluation of critical bridge infrastructure in Cebu, Philippines 

      Bernales, Francis Jenner; Selda, Patrick Adrian; Quebral, Ramon; Luna, Roy Anthony (2023-04-19)
      Long-span, inter-island bridges in active tectonic regions are exposed considerably to elevated seismic risks. Evaluation of the seismic hazard is a primary step to assess this risk. Baseline information can be obtained ...

    • Understanding and Improving the Seismic Resilience of Hospital Buildings 

      Brunsdon, Dave; Stannard, Mike (2023-04-19)
      The establishment of Te Whatu Ora – Health New Zealand has enabled more direct national oversight of public hospital buildings across New Zealand. This has also led to the need for a more comprehensive understanding of ...

    • Using 3D geological models to create maps of estimated Vs30 and site period 

      Hill, Matthew; Kaiser, Anna; Wotherspoon, Liam; Manea, Elena (2023-04-19)
      The 30-m time-averaged shear-wave velocity (Vs30) and the fundamental site period (T0) are useful parameters for understanding site conditions, informing geotechnical studies as well as infrastructure planning. Unfortunately, ...

    • Vs30 Assessments: Understanding the Underground 

      Ingham, Lizzie; McConachie, Nick (2023-04-19)
      Understanding the vulnerability of a construction site to seismic shaking is fundamental to robust building design in New Zealand. The recent release of the updated National Seismic Hazard Model reflects this, with an ...
