This paper describes the pounding damage sustained by buildings in the February 2011 Christchurch earthquake. Approximately 6% of buildings in Christchurch CBD were observed to have suffered some form of serious pounding damage. Typical and exceptional examples of building pounding damage are presented and discussed. Almost all building pounding damage occurred in unreinforced masonry buildings, highlighting their vulnerability to this phenomenon. Modern buildings were found to be vulnerable to pounding damage where overly stiff and strong ‘flashing’ components were installed in existing building separations. Soil variability is identified as a key aspect that amplifies the relative movement of buildings, and hence increases the likelihood of pounding damage. Building pounding damage is compared to the predicted critical pounding weaknesses that have been identified in previous analytical research.

The cartoon depicts a rose window set in a stone wall. The glass circles each contain a dollar sign. Refers to the future of the Christchurch Cathedral after the Canterbury earthquakes of 2010 and 2011. The Anglican Church seemed to only consider the money in arguing that it would be too expensive to be repaired or rebuilt. Title from file name Quantity: 1 digital cartoon(s).

The 22nd February 2011, Mw 6.3 Christchurch earthquake in New Zealand caused major damage to critical infrastructure, including the healthcare system. The Natural Hazard Platform of NZ funded a short-term project called “Hospital Functions and Services” to support the Canterbury District Health Board’s (CDHB) efforts in capturing standardized data that describe the effects of the earthquake on the Canterbury region’s main hospital system. The project utilised a survey tool originally developed by researchers at Johns Hopkins University (JHU) to assess the loss of function of hospitals in the Maule and Bío-Bío regions following the 27th February 2010, Mw 8.8 Maule earthquake in Chile. This paper describes the application of the JHU tool for surveying the impact of Christchurch earthquake on the CDHB Hospital System, including the system’s residual capacity to deliver emergency response and health care. A short summary of the impact of the Christchurch earthquake on other CDHB public and private hospitals is also provided. This study demonstrates that, as was observed in other earthquakes around the world, the effects of damage to non-structural building components, equipment, utility lifelines, and transportation were far more disruptive than the minor structural damage observed in buildings (FEMA 2007). Earthquake related complications with re-supply and other organizational aspects also impacted the emergency response and the healthcare facilities’ residual capacity to deliver services in the short and long terms.

This paper provides a comparison between the strong ground motions observed in the Christchurch central business district in the 4 September 2010 Mw7.1 Darfield, and 22 February 2011 Mw6.3 Christchurch earthquakes with those observed in Tokyo during the 11 March 2011 Mw9.0 Tohoku earthquake. Despite Tokyo being located approximately 110km from the nearest part of the causative rupture, the ground motions observed from the Tohoku earthquake were strong enough to cause structural damage in Tokyo and also significant liquefaction to loose reclaimed soils in Tokyo bay. Comparisons include the strong motion time histories, response spectra, significant durations and arias intensity. The implications for large earthquakes in New Zealand are also briefly discussed.

A video of interviews with four Christchurch residents about their experiences during the 22 February 2011 earthquake. The residents include David Sandeman, who was in the PGC Building when the earthquake struck, Tristan Roberts, a member of the New Zealand Fire Service who assisted after the earthquake, Claudia McFie, who was in Cashel Street when the earthquake struck, and Belinda Van Gruting, a doctor in Christchurch. This video was part of The Press's 'Christchurch, one year after February 22, 2011' series.

The badly twisted Medway Street footbridge. The photographer comments, "The September 4th 2010 earthquake in Christchurch was so violent that the banks of the Avon River moved towards each other. This footbridge being metal had to twist sideways to release the pressure of being pushed from both river banks. It looked like it had been wrung out like a wet towel".

The recent earthquakes in Canterbury have left thousands of Christchurch residents’ homeless or facing the possibility of homelessness. The New Zealand Government, so far, have announced that 5,100 homes in Christchurch will have to be abandoned as a result of earthquake damaged land (Christchurch City Council, 2011). They have been zoned red on the Canterbury Earthquake Recovery Authority (CERA) map and there are another 10,000 that have been zoned orange, awaiting a decision (Christchurch City Council, 2011). This situation has placed pressures on land developers and local authorities to speed up the process associated with the development of proposed subdivisions in Christchurch to accommodate residents in this situation (Tarrant, 2011).

Locations are chiefly Manchester, Saint Asaph, Cashel, Columbo and Lichfield Streets, and the Bridge of Remembrance. Images show fencing around areas closed to the public, damaged and collapsed commercial buildings, cleared sites, re-opened Cashel Street area with shops and a cafe.

A digitally manipulated image of a broken window. The photographer comments, "There is hardly anything left of Christchurch's proud heritage buildings. Most older buildings were made of brick and though they should have had improvements to make them withstand a medium earthquake most did not. They were badly damaged when hit with a series of earthquakes that were up to 2.2g at the epicentre and 1.88g in the City".

The 22 February 2011, Mw6.2 Christchurch earthquake is the most costly earthquake to affect New Zealand, causing an estimated 181 fatalities and severely damaging thousands of residential and commercial buildings. This paper presents a summary of some of the observations made by the NSF-sponsored GEER Team regarding the geotechnical/geologic aspects of this earthquake. The Team focused on documenting the occurrence and severity of liquefaction and lateral spreading, performance of building and bridge foundations, buried pipelines and levees, and significant rockfalls and landslides. Liquefaction was pervasive and caused extensive damage to residential properties, water and wastewater networks, high-rise buildings, and bridges. Entire neighborhoods subsided, resulting in flooding that caused further damage. Additionally, liquefaction and lateral spreading resulted in damage to bridges and to stretches of levees along the Waimakariri and Kaiapoi Rivers. Rockfalls and landslides in the Port Hills damaged several homes and caused several fatalities.

Following the magnitude 6.3 aftershock in Christchurch, New Zealand, on 22 February 2011, a number of researchers were sent to Christchurch as part of the New Zealand Natural Hazard Research Platform funded “Project Masonry” Recovery Project. Their goal was to document and interpret the damage to the masonry buildings and churches in the region. Approximately 650 unreinforced and retrofitted clay brick masonry buildings in the Christchurch area were surveyed for commonly occurring failure patterns and collapse mechanisms. The entire building stock of Christchurch, and in particular the unreinforced masonry building stock, is similar to that in the rest of New Zealand, Australia, and abroad, so the observations made here are relevant for the entire world.
