Damage to River Road in Richmond. The road surface is badly cracked and slumped, and liquefaction silt covers part of the road. The photographer comments, "Liquefaction in River Rd. This is minor compared to many streets in town".
A group of residents stand on River Road in Richmond. The road is badly cracked and buckled, and bas been partly blocked off with road cones and warning tape. The photographer comments, "Neighbours discussing the situation".
Damage to a building in Victoria Street. Part of the facade has fallen, and the rest is leaning forward and in danger of falling onto the road below. The photographer comments, "Shops in Victoria St, facades leaning forward over footpath".
Detail of damage to a house in Richmond. The brick wall is badly cracked and twisted. The photographer comments, "These photos show our old house in River Rd and recovery work around Richmond and St Albans. More ruptured brickwork".
The Avon River in Richmond. The river level is very high, and the water is grey with silt. The photographer comments, "By the corner of Medway St and River Rd. The Avon seems to be very full, with grey silt laden water".
A photograph of the declinator readout ring from the Townsend Telescope. The ring was chipped and scratched during the 22 February 2011 earthquake.

This paper presents on-going challenges in the present paradigm shift of earthquakeinduced ground motion prediction from empirical to physics-based simulation methods. The 2010-2011 Canterbury and 2016 Kaikoura earthquakes are used to illustrate the predictive potential of the different methods. On-going efforts on simulation validation and theoretical developments are then presented, as well as the demands associated with the need for explicit consideration of modelling uncertainties. Finally, discussion is also given to the tools and databases needed for the efficient utilization of simulated ground motions both in specific engineering projects as well as for near-real-time impact assessment.
