Web interface for earthquake and ground motion simulation visualisation

Abstract

This poster presents two recently deployed web interfaces for data visualisation associated with New Zealand earthquakes, consequent ground motions, and geotechnical conditions. Simulation Atlas (http://atlas.seistech.nz) provides a map-based visualisation of the historically-observed and potential future earthquakes on major known faults in New Zealand and key information about them, such as tectonic type, anticipated magnitude of a potential rupture, and probability in 50 years. For selected faults (100 at present), it provides the 3D animation of the potential ground motion produced by GMSimViz, an in-house-developed automation tool that converts the ground motion simulation output into a 3D animation. NZ Vs30 model viewer (https://vs30.seistech.nz) allows users to visualise and query Vs30 estimates for Geology, Terrain and combined models for a specified location as well as geology and terrain categories. This gives an improved visibility about how a Vs30 is chosen making it easy to verify the value intuitively and also identify areas for improving such models for regional applications.
