Damage to the the shops on the corner of Colombo Street and Bealey Avenue. The facade on the roof has crumbled, as well as the awning over the pharmacy. Road cones, tape and fences bar the public for their own safety.
A photograph of workers from ADT Security sitting outside the temporary Civil Defence headquarters set up at the Mainland Foundation Ballpark after the 4 September earthquake.
A photograph of a digger being used to clear the rubble of a collapsed house on Worcester Boulevard. Fire damage can be seen along the right side of the house next door.

A photograph of the earthquake damage to a building on Manchester Street. The top railing of the faรงade has fallen away and cracks can be seen in the brickwork of the wall below.
A photograph of the earthquake damage to R&R Sport on the corner of Colombo and Tuam Streets. Most of the side wall has crumbled, exposing the wooden structure beneath.

A photograph of The Fish & Chip Shop in SOL Square with Fat Eddie's to the right. Lights have been strung over the courtyard and a car can be seen on the wall of the building behind.
A photograph of the earthquake damage to the White's Building on Tuam Street, visible through a broken window. The roof of the building has collapsed into the building, a plank of wood breaking through the window.
A photograph of piles of silt on the side of a road in Christchurch. This has been dug out of people's properties and placed on the road to be picked up by the Council.
The site of Gap Filler's first project at 832 Colombo Street. A mobile coffee vender can be seen as well as a garden made out of pot plants and lots of seating.
Damage to the the shops on the corner of Colombo Street and Bealey Avenue. The facade on the roof has crumbled, as well as the awning over the pharmacy. Road cones, tape and fences bar the public for their own safety.
A Mr Whippy van at Gap Filler's first project at 832 Colombo Street. In the background, the Gap Filler logo has been pinned to a wire fence next to the site.
Damage to the Gayhurst Road bridge. The road has buckled due to the bridge's movement, and the bridge is cordoned off. Liquefaction covers part of the street, and in the background St Paul's Church is also cordoned off.
We present ground motion simulations of the Porters Pass (PP) fault in the Canterbury region of New Zealand; a major active source near Christchurch city. The active segment of the PP fault has an inferred length of 82 km and a mostly strike-slip sense of movement. The PP fault slip makes up approximately 10% of the total 37 mm/yr margin-parallel plate motion and also comprises a significant proportion of the total strain budget in regional tectonics. Given that the closest segment of the fault is less than 45 km from Christchurch city, the PP fault is crucial for accurate earthquake hazard assessment for this major population centre. We have employed the hybrid simulation methodology of Graves and Pitarka (2010, 2015), which combines low (f<1 Hz) and high (f>1 Hz) frequencies into a broadband spectrum. We have used validations from three moderate magnitude events (๐๐ค4.6 Sept 04, 2010; ๐๐ค4.6 Nov 06, 2010; ๐๐ค4.9 Apr 29, 2011) to build confidence for the ๐๐ค > 7 PP simulations. Thus far, our simulations include multiple rupture scenarios which test the impacts of hypocentre location and the finite-fault stochastic rupture representation of the source itself. In particular, we have identified the need to use location-specific 1D ๐๐ /๐๐ models for the high frequency part of the simulations to better match observations.
A signi๏ฌcant portion of economic loss from the Canterbury Earthquake sequence in 2010-2011 was attributed to losses to residential buildings. These accounted for approximately $12B of a total $40B economic losses (Horspool, 2016). While a significant amount of research effort has since been aimed at research in the commercial sector, little has been done to reduce the vulnerability of the residential building stock.
A sculpture titled 'Passing Time' on the corner of St Asaph Street and Madras Street. 'Passing Time' was installed outside the CPIT Building for the 6th SCAPE (a contemporary public art programme in Christchurch) a few days prior to the 22 February 2011 earthquake. The work features twisting boxes depicting each year between 1906 (the founding of CPIT) and 2010 (the date of the sculpture's production).
