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 (𝑀𝑤4.6 Sept 04, 2010; 𝑀𝑤4.6 Nov 06, 2010; 𝑀𝑤4.9 Apr 29, 2011) to build confidence for the 𝑀𝑤 > 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 𝑉𝑠/𝑉𝑝 models for the high frequency part of the simulations to better match observations.
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).

A section of footpath outside a property on Robson Avenue in Avonside from which the pavement has been removed due to damage from the 4 September 2010 earthquake. The lid of a buried septic tank can be seen in front of the property's front lawn. These tanks were installed in front of Avonside properties to allow residents to use their toilets after the September earthquake.
A group of residents stand talking on the footpath beside River Road. The photographer comments, "Our neighbours were mostly already displaced by the Sep 4 2010 quakes. We all happened to arrive at the same time, so we had a good chat. From L-R; Deidre Crichton (389), Julie and Philip Cheyne (391), Marike Begg (363), Susannah and Kim Collins (383), Andy Corbin (389)".
A significant 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.
Damage to retail buildings on High Street. Shops shown include Burgers & Beers, as well as boutique clothing stores Embassy and Plush. All are cordoned off for safety. A collapsed ceiling is visible through the windows above Burgers & Beers.
A photograph of the earthquake damage to a building on the corner of Manchester Street and Struthers Lane. The front wall of the building has crumbled, exposing the rooms inside. One is covered in graffiti.
A photograph of the Durham Street Methodist Church blocked off by wire fencing. The tip of the façade is damaged, and bracing holds it up from behind.
A photograph of the earthquake damage to Pretty Things on Colombo Street. Wire fencing, road cones and Civil Defence tape have been placed around the buildings as a cordon.
