Project Abstract
The annual SCEC meeting attendance allowed Dr Caroline Holden to present her research related to near source ground motion simulations to study the relationship between ground motion intensity metrics and earthquake rupture parameters, as well as comparison with predictions from ground motion prediction equations (GMPEs).

Holden and Kaiser's work is making use of the wealth of data from the Canterbury earthquakes: excellent
dense near source recordings as well as detailed kinematic source models for the largest aftershocks (Holden and Beavan, 2012). Their work is expanding to major fault rupture modelling such as the New Zealand Alpine fault (Holden (2014), Holden and Kaiser (2015)).
Intellectual Merit Holden's contribution to the meeting is of relevance to California since the Canterbury data provides a unique insight into near-source ground motion observations and simulations.
Dr Holden has been a regular attendee of the SCEC meeting. She has been granted travel funds to attend the 2015 meeting for her proposal on “Near source broadband ground-motion modelling of the Canterbury aftershocks and implications for assessing engineering metrics”.
Broader Impacts The 2014 annual SCEC meeting allowed Holden to incorporate the Ground Motion Simulation Validation technical activity (GMSV) group, of which she was an active participant. A 2016 travel grant allowed her not only to present her work progress now extended to modelling of the Alpine fault and interact with the SCEC community but also to actively participate to GMSV meeting and discussions.
