Canterbury research on earthquake engineering and resilient infrastructure
February 12, 2015
Civil and natural resources engineers at the University of Canterbury are developing new technologies to evaluate the
effects of earthquake-induced ground movement on buildings and facilities critical for the safety and well-being of
communities throughout New Zealand.
Professor Tom O’Rourke of Cornell University, a University of Canterbury visiting Erskine fellow, is researching the
issue with Professors Misko Cubrinovski and Brendon Bradley and Dr Matt Hughes. The Erskine fellowship programme was
established in 1963 following a generous bequest by distinguished former student John Erskine.
The four are investigating how soil and rock behave in response to earthquakes and other natural hazards, such as floods
and landslides. They are using advanced soil exploration and testing techniques, light detection and ranging technology
and geographical information systems to understand how earthquakes and natural hazards affect lifeline systems.
Professor O’Rourke is teaching a course at the University of Canterbury which focuses on case histories of extreme
events, their effects on infrastructure, and ways to develop resilient communities through improved systems performance.
Case histories will include the World Trade Center Disaster, Hurricane Katrina, Hurricane Sandy, Tohoku earthquake, San
Francisco earthquakes, the Northridge earthquake and the Canterbury earthquakes.
“Lifelines are large geographically distributed systems, such as electric power, gas and liquid fuels,
telecommunications, transportation, water supplies, and wastewater conveyance and treatment facilities,” Professor
O’Rourke says.
“They are intricately linked with the economic well-being, security, and social fabric of the communities they serve. In
many ways, lifelines define modern society. The effectiveness with which resources and services are delivered through
lifeline systems influences, both locally and nationally, gross domestic product, jobs and household income, energy
independence, and economic competitiveness.”
Professor O’Rourke worked in New Zealand in 2007 as a senior specialist supported by the Fulbright Foundation, with the
Office of the Prime Minister and Cabinet in Wellington. He helped develop national policy for natural hazards and the
mitigation of their impact on lifeline systems.
He is a frequent visitor to New Zealand, and has helped in the recovery of Christchurch from the 2010 and 2011
earthquakes. He provided external review for plans to rebuild roads, water delivery, wastewater conveyance, and drainage
systems in Christchurch.
He has provided advice for Stronger Christchurch Infrastructure Rebuild Team (SCIRT) in the restoration of water and
wastewater systems in Christchurch and for the Lyttelton Port of Christchurch in evaluating ground conditions and
construction methods for the port facilities.
Before arriving at the University of Canterbury he chaired a United States national study of earthquake-resilient
lifelines, conducted through the Applied Technology Council under the sponsorship of the US National Institute for
Standards and Technology.
That study produced a roadmap for research, development and implementation of technologies and policies for improved
community resilience to earthquakes through the betterment of lifeline system performance. There are many relevant
lessons for New Zealand in this study, Professor O’Rourke says.
