The large number of earthquake-prone vintage unreinforced masonry (URM) buildings in many seismically active parts of the world results in a need for minimally invasive and cost-effective strengthening techniques to enhance the poor earthquake performance of such buildings. The objective of the research reported here was to investigate the applicability of using near-surface-mounted (NSM) carbon fiber–reinforced polymer (CFRP) strips as a retrofitting technique for improving the in-plane shear strength and displacement capacity of multi-leaf URM walls constructed using solid clay brick masonry. The use of this technique for repairing earthquake damaged URM walls was also investigated. Ten multileaf wall panels measuring approximately 1,200×1,200  mm 1,200×1,200  mm were constructed using recycled vintage solid clay bricks and retrofitted using NSM CFRP strips with varying reinforcement ratios. These panels were loaded in diagonal compression, and the results were compared with those obtained from testing of nominally identical unretrofitted wall panels constructed using the same materials. In addition, four wall panels extracted from existing buildings were tested in an as-built condition and then later retested after being repaired using the NSM CFRP strip technique. Based on the experimental results it was established that the NSM CFRP strip technique provides a simple and cost effective method for substantially enhancing the shear strength and displacement capacity of understrength or damaged URM wall panels http://ascelibrary.org/journal/jccof2

Billy Kristian of The Invaders shares his memories of Ray Columbus who has died at the age of 74. Islay Marsden of the University of Canterbury discusses what clearing rocks and silt from quake-induced landslides will do to the coastal environment. Kevin Furlong of Penn State University discusses the connection between the earthquakes and various faultline systems.

The cartoon depicts the Minister of Earthquakes Gerry Brownlee, with a portaloo in place of a head. He holds in his hand a document which reads 'Govt appointed quake panel (Shipley etc) paid twice normal fees: $1000 - 1400 daily'. A voice from inside the toilet says 'It's because they're high calibre people!' Context: Earthquake Recovery Minister Gerry Brownlee lobbied his colleagues to pay a Government-appointed panel more than twice the recommended rate because he claimed they would not do it for less - even though he never asked them. On Mr Brownlee's advice, the Cabinet more than doubled the pay rates for the panel from the recommended fees, which was a daily rate of $360 to $655 for the panel chairman and $270 to $415 for panel members. The Cabinet increased this to $1400 a day for the chairman and $1000 a day for the other members. (NZ Herald, 9 August 2011) Quantity: 1 digital cartoon(s).

The panel is titled, "Engaging: Generating Community Input and Feedback".Leanne Curtis of Breakthrough Services, Evan Smith, Programme Manager of Eastern Vision, and André Lovatt, CEO of the Arts Centre, present case studies.The theme of the panel reads, "'Regenerate Christchurch must and will engage with the community around what will be done' (André Lovatt, Chair, Regenerate Christchurch). Learning from the past by tapping the wisdom of communities and applying the lessons to the future as we shape the new city."

A video of a presentation by Antony Gough, New Zealand property developer, during a panel at the 2016 Seismics in the City Conference. The panel has three themes:A City on the Move: Collaboration and Regeneration: "'Christchurch is now moving rapidly from the recovery phase into a regeneration stage with Central and Local Government working with the wider community, including the business community to ensure we get optimal outcomes for greater Christchurch' (CECC)."Looking Back: Remembering and Learning: "What are the milestones? What are the millstones? What have we learnt? What have we applied?"Looking Forward: Visioning and Building: "What do we aspire to? What are the roadblocks? What is the way forward?"
