Having a quick but reliable insight into the likelihood of damage to bridges immediately after an earthquake is an important concern especially in the earthquake prone countries such as New Zealand for ensuring emergency transportation network operations. A set of primary indicators necessary to perform damage likelihood assessment are ground motion parameters such as peak ground acceleration (PGA) at each bridge site. Organizations, such as GNS in New Zealand, record these parameters using distributed arrays of sensors. The challenge is that those sensors are not installed at, or close to, bridge sites and so bridge site specific data are not readily available. This study proposes a method to predict ground motion parameters for each bridge site based on remote seismic array recordings. Because of the existing abundant source of data related to two recent strong earthquakes that occurred in 2010 and 2011 and their aftershocks, the city of Christchurch is considered to develop and examine the method. Artificial neural networks have been considered for this research. Accelerations recorded by the GeoNet seismic array were considered to develop a functional relationship enabling the prediction of PGAs. http://www.nzsee.org.nz/db/2013/Posters.htm
A photograph looking east down Gloucester Street, towards the intersection of Manchester Street. On-lookers are surveying earthquake damage from behind the cordon. The Christchurch City Council parking building can be seen in the distance.
A view across Madras Street to St Pauls Trinity-Pacific Presbyterian Church. Scaffolding has been constructed around the building to enable repairs to be made. The church was damaged in the 4 September 2010 earthquake.
Tents set up in the Arts car park at the University of Canterbury after the 22 February 2011 earthquake. The tents were used as temporary lecture rooms while the buildings were being checked for damage.

A photograph of the earthquake damage to a building on Lichfield Street. The brick wall of the top storey of the building has crumbled, exposing the wooden structure underneath. Many of the windows are broken.
A photograph of the earthquake damage to a group of stores on Manchester Street including the While You Wait Studio, Smith's Bookshop, Aji Global Grocery & Chocolateria and Curios Bric-a-Brac. Sections of the front wall have crumbled, the bricks falling to the footpath and damaging the awnings. Plastic fencing has been placed along the road as a cordon.
A photograph of the earthquake damage to the Edward Gibbon building on Madras Street. Sections of the top storey have collapsed and the bricks have spilled onto the road in front, damaging the awning and smashing several cars. In the foreground members of the Wellington Emergency Management Office Emergency Response Team are standing on the road.
Damage to Fitzgerald Avenue. The northbound lanes have collapsed towards the river, and a pile of rubble from the damaged road is heaped on the road. Road cones divert traffic onto the southbound lanes. The photographer comments, "Fitzgerald Avenue between Kilmore Street and Bealey Ave is a mess. Half of the road has slumped towards the river by a good metre or two. My brother-in-law was here when the 22nd earthquake hit and he said the damage wasn't as bad as this at first. A local resident told me that the road is slumping more and more each day".
