Recently we’ve been working in Lyttelton at the intersection of Canterbury and Winchester Streets for the installation of a replacement stormwater. While Lyttelton isn’t exactly over the rainbow, for archaeologists it is a pretty fantastic place to discover heritage and … Continue reading →
This study provides an initial examination of source parameter uncertainty in a New Zealand ground motion simulation model, by simulating multiple event realisations with perturbed source parameters. Small magnitude events in Canterbury have been selected for this study due to the small number of source input parameters, the wealth of recorded data, and the lack of appreciable off-fault non-linear effects. Which provides greater opportunity to identify systematic source, path and site effects, required to robustly investigate the causes of uncertainty.
