University of Canterbury Earthquake Risk Research: High-Tech Tools Harnessed to Plot NZ's Future Quake Risk

Seismic Innovation Takes Centre Stage at University of Canterbury

Fifteen years after the devastating Christchurch earthquake shook New Zealand to its core, the University of Canterbury (UC) continues to lead the charge in earthquake risk research. Recently, two UC researchers secured significant funding from the Natural Hazards Commission Toka Tū Ake to deploy high-tech tools aimed at mapping future quake risks more precisely. Dr Camilla Penney from the School of Earth and Environment and Dr Robin Lee from the Department of Civil and Environmental Engineering received grants totalling $175,000 under the 2026 Biennial Grants programme. These projects promise trial forecasts indicating where and when earthquakes might strike, enhancing national resilience in a country straddling the Pacific Ring of Fire.

UC's longstanding expertise in seismic science, honed through its hosting of QuakeCoRE—a Centre of Research Excellence dedicated to earthquake resilience—positions it uniquely. QuakeCoRE unites physical, engineering, and social scientists, incorporating mātauranga Māori knowledge to foster rapid community recovery. This latest funding underscores UC's pivotal role in translating academic research into practical safeguards for Aotearoa New Zealand.

Legacy of Christchurch: Driving UC's Research Imperative

The 2011 Christchurch earthquake, a magnitude 6.3 event on 22 February, claimed 185 lives and caused widespread destruction, particularly due to soil liquefaction in the Canterbury region. As New Zealand's second-largest city grappled with recovery, UC researchers pivoted to analyse the unprecedented data from the Canterbury Earthquake Sequence—a series of over 12,000 events. This real-world laboratory spurred innovations in ground motion prediction and structural resilience.

Today, with the 15th anniversary approaching, UC builds on that foundation. The region's experience highlighted how local ground conditions amplify shaking, a factor central to current projects. For students and academics eyeing careers in geohazards, UC offers robust programmes; explore openings via university jobs in New Zealand's premier seismic hub.

Dr Camilla Penney's Statistical Bridge to Future Forecasts

Dr Camilla Penney's $100,000 grant targets a critical disconnect: New Zealand's 150 years of recorded earthquakes versus physics-based simulations spanning 500,000 years on known faults. Her approach develops new statistical methods to rigorously test these simulations against historical data, ensuring reliability for seismic hazard models.

The process unfolds step-by-step: First, compile instrumental records from seismometers (deployed ~70 years ago) and paleoseismic evidence. Next, generate synthetic earthquake catalogues using simulators like RSQSim, which model fault interactions. Finally, apply statistical validation to calibrate forecasts. This could yield New Zealand's first trial predictions of quake locations and timings, vital for the National Seismic Hazard Model (NSHM).University of Canterbury's announcement

Challenges abound, as Dr Penney notes: Many damaging quakes, like the 2016 Kaikōura event rupturing over 20 faults, occur on unknown lines. Models illuminate complexity—how one rupture triggers others—but cannot foresee undiscovered faults. Limited Māori oral histories offer untapped potential, demanding culturally sensitive integration.

Dr Robin Lee's Machine Learning Revolution in Ground Mapping

Complementing Penney's work, Dr Robin Lee's $75,000 project leverages machine learning on 20,000 geotechnical tests from the New Zealand Geotechnical Database (NZGD). These measurements gauge soil stiffness and strength during site investigations. The goal: Update the Vs30 map—measuring shear wave velocity (Vs) in the top 30 metres—to pinpoint amplification hotspots.

Current maps rely on under 400 sites, mostly Canterbury-based, with crude national extrapolations. Lee's method integrates modern statistics and AI to process dense, varied data: soil type, density, layer thickness all modulate shaking. Soft, loose soils can double or triple intensities, turning survivable quakes deadly.

Open-access outputs will empower engineers and planners. As Lee explains, it's beyond rock versus soil—subtle variances dictate damage. For higher ed career advice on geotechnical roles, check higher ed career advice.

QuakeCoRE and NSHM: UC's National Backbone

Hosted by UC, QuakeCoRE advances system-level science for resilience, partnering with 12 institutions and Māori sectors. It treats New Zealand as a 'natural laboratory', blending engineering seismology, geodesy, and social sciences.GNS NSHM page

The NSHM, led by GNS with UC luminaries like Prof Brendon Bradley, aggregates models for shaking probabilities over 10-100 years. The 2022 update raised hazards by 50% nationwide, factoring subduction zones like Hikurangi. UC contributions refine seismicity rates and ground motions, directly informing Penney and Lee's tools.

Prof Brendon Bradley's Scott Medal recognises ground-motion simulations identifying peak-shaking zones. Prof Santiago Pujol's research proves 1% storey drift limits slash post-quake abandonment, influencing 2027 codes. Dr Chris de la Torre fine-tunes NSHM's nonlinear site responses, curbing overestimations.
