The sequence of earthquakes that has greatly affected Christchurch and Canterbury since September 2010 has again demonstrated the need for seismic retrofit of heritage unreinforced masonry buildings. Commencing in April 2011, the damage to unreinforced stone masonry buildings in Christchurch was assessed and recorded with the primary objective being to document the seismic performance of these structures, recognising that they constitute an important component of New Zealand’s heritage architecture. A damage statistics database was compiled by combining the results of safety evaluation placarding and post-earthquake inspections, and it was determined that the damage observed was consistent with observations previously made on the seismic performance of stone masonry structures in large earthquakes. Details are also given on typical building characteristics and on failure modes observed. Suggestions on appropriate seismic retrofit and remediation techniques are presented, in relation also to strengthening interventions that are typical for similar unreinforced stone masonry structures in Europe.

Cartoons about political and social issues in New Zealand and overseas. The cartoon has the words 'Tsunami Warning cancelled' in the centre. Above are the words 'The end is nigh... insurance running out! No more cover!' Below the word 'cancelled' are the words 'We have reinsurance!' Context - Civil Defence has cancelled a tsunami warning after a 7.8 magnitude earthquake struck off the Kermadec Islands this morning (7 July 2011) The tsunami image is used to illustrate the problems that could arise from lack of insurance in Christchurch. When their policies run out on 30 June Earthquake-hit Christchurch and Waimakariri councils are in danger of having no property insurance because as the CEO of Civic Assurance, which insures most councils, says, 'the company cannot buy reinsurance'. There was also a potential problem for home-owners when AMI Insurance, the largest insurer of homes in Christchurch, was threatening insolvency. However, AMI has announced that it has re-insurance cover for earthquakes and other natural disasters from tomorrow (1 July 2011) for the next year. The Government feared AMI Insurance's directors would wind up the company affecting a huge section of New Zealand's insurance market and derail the reconstruction of Christchurch, official documents confirm. AMI said it had doubled its cover for the year to June 2012 after three large quakes in the year to June 2011. (Stuff 30 June 2011) Quantity: 1 digital cartoon(s).
