New Zealand-specific ground motion prediction
The matlab files here provide the matlab source code and example of the Bradley (2013) empirical ground motion prediction equation for pseudo-spectral accelerations from active shallow crustal earthquakes in New Zealand.
Strong ground motion data from the Canterbury earthquakes
These ground motions can be manipulated using software such as Seismosignal
Ground motion data from the 4 September 2010 Darfield Earthquake (from Bradley (2012)).
Ground motion data from the 22 February 2011 Christchurch Earthquake (from Bradley and Cubrinovski (2011)).
Ground motion data from the 13 June 2011 Mw6.0 Christchurch Earthquake (from Bradley (2016)).
Ground motion data from the 23 December 2011 Mw5.9 Christchurch Earthquake (from Bradley (2013)).
Spatial distribution of peak ground acceleration from the Canterbury earthquakes
The spatial distribution of peak ground acceleration throughout the Canterbury region has been computed. The purpose of such a computation is to enable the back-analysis of liquefaction triggering of surficial soil deposits. This work has been commissioned by the Department of Building and Housing (DBH), and is provided here on their behalf.
