Earthquake Commemorative Lecture: Liquefaction – What is it, why it matters and what we can do about it

This is the commemorative lecture for 1931 Hawke’s Bay Earthquake, also known as the Napier earthquake, which occurred at 10:47am on 3 February 1931, killing 256, injuring thousands and devastating the Hawke’s Bay region. This year Rick Wentz is invited to give a lecture on liquefaction. The focus of this lecture will be to define liquefaction, describe the cause and the conditions under which it typically occurs, and to highlight its potential impacts on the built environment. Also discussed will be some things that individuals and communities can consider doing to reduce the impacts of liquefaction on homes and infrastructure.
