A local musician entertaining University of Canterbury students inside the UCSA's "Big Top" tent. The tent was erected in the UCSA car park to provide support for students in the aftermath of the 22 February 2011 earthquake. The students have spent the day clearing liquefaction from Christchurch properties as part of the Student Volunteer Army.

Geotechnical Aspects of the 22 February 2011 Christchurch earthquake
Research papers, University of Canterbury Library
The 22 February 2011, Mw6.2-6.3 Christchurch earthquake is the most costly earthquake to affect New Zealand, causing 181 fatalities and severely damaging thousands of residential and commercial buildings, and most of the city lifelines and infrastructure. This manuscript presents an overview of observed geotechnical aspects of this earthquake as well as some of the completed and on-going research investigations. A unique aspect, which is particularly emphasized, is the severity and spatial extent of liquefaction occurring in native soils. Overall, both the spatial extent and severity of liquefaction in the city was greater than in the preceding 4th September 2010 Darfield earthquake, including numerous areas that liquefied in both events. Liquefaction and lateral spreading, variable over both large and short spatial scales, affected commercial structures in the Central Business District (CBD) in a variety of ways including: total and differential settlements and tilting; punching settlements of structures with shallow foundations; differential movements of components of complex structures; and interaction of adjacent structures via common foundation soils. Liquefaction was most severe in residential areas located to the east of the CBD as a result of stronger ground shaking due to the proximity to the causative fault, a high water table approximately 1m from the surface, and soils with composition and states of high susceptibility and potential for liquefaction. Total and differential settlements, and lateral movements, due to liquefaction and lateral spreading is estimated to have severely compromised 15,000 residential structures, the majority of which otherwise sustained only minor to moderate damage directly due to inertial loading from ground shaking. Liquefaction also had a profound effect on lifelines and other infrastructure, particularly bridge structures, and underground services. Minor damage was also observed at flood stop banks to the north of the city, which were more severely impacted in the 4th September 2010 Darfield earthquake. Due to the large high-frequency ground motion in the Port hills numerous rock falls and landslides also occurred, resulting in several fatalities and rendering some residential areas uninhabitable.

Labour Party leader Phil Goff speaking to members of the Student Volunteer Army in the UCSA car park outside the UCSA's "Big Top" tent. The tent was erected to provide support for students at the University of Canterbury in the aftermath of the 22 February 2011 earthquake. Behind them members of the Student Volunteer Army are assembling wheelbarrows which will be used to clear liquefaction from Christchurch properties.

A photograph of a large trench at the entrance to a street in Christchurch. There is water and liquefaction in the trench. Road cones have been placed around it as a warning. In the background, two personnel from the New Zealand Army are guarding the entrance to the street. They are wearing their army uniforms and high-visibility vests.

A photograph of the earthquake damage to the corner of Woodham Road and Avonside Drive. There are large cracks in the road, and flooding and liquefaction. Wire fencing and road cones have been placed around parts of the road that are unsafe. Two signs reading, "Road closed" and, "No entry" can be seen at the entrance to Avonside Drive.
