Heathcote Valley school strong motion station (HVSC) consistently recorded ground motions with higher intensities than nearby stations during the 2010-2011 Canterbury earthquakes. For example, as shown in Figure 1, for the 22 February 2011 Christchurch earthquake, peak ground acceleration at HVSC reached 1.4 g (horizontal) and 2 g (vertical), the largest ever recorded in New Zealand. Strong amplification of ground motions is expected at Heathcote Valley due to: 1) the high impedance contrast at the soil-rock interface, and 2) the interference of incident and surface waves within the valley. However, both conventional empirical ground motion prediction equations (GMPE) and the physics-based large scale ground motions simulations (with empirical site response) are ineffective in predicting such amplification due to their respective inherent limitations.

A Christchurch City Council/Canterbury District Health Board/ECan sign on a tree next to the Heathcote River reads, "Warning, contaminated water. Due to sewage overflows this water is unsafe for human contact and activity and is a public health risk. Please keep all people and pets out of contact with the water and do not consume any seafood or shellfish collected from this area.".

A PDF copy of a notice of motion to the Spreydon-Heathcote Community Board on 21 October 2011 regarding hydraulic fracturing (fracking) in the Canterbury region. The speaker requested that the community board "go further than this motion as a board and call on the council, to call for a moratorium on fracking around Canterbury until a full independent review has taken place from PCE".

A PDF copy of a poster created with the All Right? Poster Generator. The poster features the responses from a number of Christchurch residents about what makes them feel good, such as "It's all right to sing! Vivien, Heathcote." The posters were placed around the city at locations such as cafes, doctors surgeries and fish and chip shops. All Right? posted this poster on their Facebook Timeline on 10 May 2013 at 4:07pm.
