Proceedings New Zealand Society for Earthquake Engineering. The July/August 2013 Lake Grassmere earthquake sequence produced two notable events which resulted in peak ground accelerations (PGAs) in excess of 0.1g on both sides of Cook Strait (GNS Science, 2013). Only earthquakes with a magnitude of 6.0 or greater are listed, except for a few that had a moderate impact.
