... to improve the understanding of water supply network seismic resilience, this paper examines in detail the initial performance and restoration of the water supply network following the 22 February 2011 M w 6.2 Christchurch, New Zealand earthquake. In addition, a method to optimize the recovery...

... recent earthquakes. However, it is not clear whether all of the observed AsVAs reflect actual ground shaking or the interaction of a building structure and underlying ground. Here, we investigate the cause of large AsVAs recorded at several seismic stations in Christchurch, New Zealand, during the 2011 M...
