These were scattered across the park.

A PDF copy of a fact sheet about hydraulic fracturing (fracking) in the South Island created by Anglican Advocacy in 2011. The fact sheet contains information about the possible impacts of fracking on water and the risk of earthquakes.
Sand volcanoes put the silt all over the road.
The earthquake knocked over the bird bath.
Debra points at the beginnings of a sand volcano not long after the big earthquake.
An usual thing to see coming from the ground in Hoon Hay, Christchurch.
Cracks in the roads and foot paths were surprisingly hard to find given the strength of the earthquake.
Laura, Nicola, and Debra watch a sand volcano build in the Wyn Street gutter.
(I righted the bird bath after the initial earthquake. None of the after-shocks were sufficient to knock it over again.)
Bruce and his cage were sitting on top of the small wooden table on the right before the earthquake. He was understandably alarmed.
The upper section of the Durham Street Methodist Church. Scaffolding has been constructed to allow workers from the South Island Organ Company to retrieve the church's valuable and historic organ. The windows at the far end have been weather proofed with plywood and strengthened with timber bracing.

And, yes, the newspaper always gets through! The Press newspapers were delivered in our area of Hoon Hay in the hours after the earthquake.

Laura and Max return to Christchurch from their holiday in California and inspect the earthquake-caused sand volcano in their front lawn.
The magnitude 7.1 Christchurch earthquake broke off an enormous chunk of Castle Rock in the Port Hills which has tumbled down towards the Lyttelton tunnel. View from Morgan's Valley (-43.578037° 172.714828°).
Telegraph Road was a straight road before the recent 7.1 magnitude earthquake. The fault ran right through here and now the road has a dramatic kink in it.
A plaque for an artwork on the corner of High Street and Tuam Street reads "'Corgis on High'. A Christchurch City Council Public Artwork. Artist David Marshall. Proudly Sponsored by Central City Revitalisation Project, Christchurch City Council, Lion Foundation, McKenzie and Willis Ltd. Supported by South Island Welsh Corgi League. 6 December 2003." The photographer comments, "The corgis have been removed. Temporarily??".
This has made a huge mess for the residents to clean up. I heard on the news that homes have been damaged by subsidence in areas of earthquake-caused liquefaction like this.
Lots of people were out and about in the streets checking on everyone after the earthquake. When it was clear that everyone was OK, the sand volcanos became the feature of interest.

It would have been a glorious Spring day in Christchurch had it not been for the magnitude 7.1 earthquake at 4:30 am. All the water and silt you can see covering the street in this photo erupted from the ground following the earthquake.
Yes, it was a joke. The tours, that is, not the yard filled with earthquake-caused sand volcanos. They were very real. You can see one covering the driveway in this photo. The signs read as follows. "Tours run 1/2 hourly. $5.25 admission. Eftpos unavailable." "If you think this is bad... you should see the back!"
Background and methodology The Mw 7.8, 14th November 2016 earthquake centred (item b, figure 1) in the Hurunui District of the South Island, New Zealand, damaged critical infrastructure across North Canterbury and Marlborough. We investigate the impacts to infrastructure and adaptations to the resulting service disruption in four small rural towns (figure 1): Culverden (a), Waiau (c), Ward (d) and Seddon (e). This is accomplished though literary research, interviews and geospatial analysis. Illustrating our methods, we have displayed here a Hurunui District hazard map (figure 2b) and select infrastructure inventories (figures 2a, 3).
We present initial results from a set of three-dimensional (3D) deterministic earthquake ground motion simulations for the northern Canterbury plains, Christchurch and the Banks Peninsula region, which explicitly incorporate the effects of the surface topography. The simu-lations are done using Hercules, an octree-based finite-element parallel software for solving 3D seismic wave propagation problems in heterogeneous media under kinematic faulting. We describe the efforts undertaken to couple Hercules with the South Island Velocity Model (SIVM), which included changes to the SIVM code in order to allow for single repetitive que-ries and thus achieve a seamless finite-element meshing process within the end-to-end ap-proach adopted in Hercules. We present our selection of the region of interest, which corre-sponds to an area of about 120 km × 120 km, with the 3D model reaching a depth of 60 km. Initial simulation parameters are set for relatively high minimum shear wave velocity and a low maximum frequency, which we are progressively scaling up as computing resources permit. While the effects of topography are typically more important at higher frequencies and low seismic velocities, even at this initial stage of our efforts (with a maximum of 2 Hz and a mini-mum of 500 m/s), it is possible to observe the importance of the topography in the response of some key locations within our model. To highlight these effects we compare the results of the 3D topographic model with respect to those of a flat (squashed) 3D model. We draw rele-vant conclusions from the study of topographic effects during earthquakes for this region and describe our plans for future work.
