EQs much more damaging to basin edge in Wellington - study
Tim Stern, emeritus professor and geophysicist who led gravity-modelling of the Wellington Basin. He explains how soft basin sediments slow and amplify seismic waves. He describes gravity and seismic surveys that revealed a deeper, sharper basin edge. He points to localized edge amplification in parts of central Wellington and notes similar risks for other basin-built NZ cities.
