The sequence of earthquakes that has affected Christchurch and Canterbury since September 2010 has caused damage to a great number of buildings of all construction types. Following post-event damage surveys performed between April 2011 and June 2011, the damage suffered by unreinforced stone masonry buildings is reported and different types of observed failures are described. A detailed technical description of the most prevalently observed failure mechanisms is provided, with reference to recognised failure modes for unreinforced masonry structures. The observed performance of existing seismic retrofit interventions is also provided, as an understanding of the seismic response of these interventions is of fundamental importance for assessing the vulnerability of similar strengthening techniques when applied to unreinforced stone masonry structures.

A photograph of an ICOM IDAS Repeater next to the information for the Civil Defence Response Team networks. The IDAS is a digital land mobile radio system which retransmits radio signals. It was used by the Civil Defence to extend the range of their digital radios during the emergency response to the 22 February 2011 earthquake.
