Australian Ground-motion Records Portal
Description:
We introduce a web portal designed to provide seamless access to consistently processed Australian ground-motion records and key engineering parameters, offering a powerful tool for researchers, and engineers. The portal leverages the USGS gmprocess software to consistently process ground-motion data and compute engineering parameters of interest. These processed datasets are then integrated into the database, which supports advanced queries based on earthquake parameters (e.g., magnitude, origin time, depth), ground motion metrics (e.g., peak ground acceleration and velocity, response spectral acceleration), and source-to-site distance metrics (e.g., hypocentral distance). Search results can be downloaded in CSV format, including key earthquake, site condition, and source-to-site distance parameters, along with computed engineering metrics. Additionally, processed waveforms are available for download in the standard COSMOS format.
The portal enhances user experience with interactive visual tools, featuring layers that display earthquake locations, recording stations, Australia's seismic site condition map, neotectonic domains, and national seismic hazard maps (current and legacy). Users can explore photographs of recording stations and gain event-specific insights, such as waveform section plots and user-friendly summaries of earthquake, station, and ground motion parameters. The platform also enables users to compare recorded ground motions with ground-motion models in an interactive and flexible manner. With its user-friendly interface and robust features, this platform can significantly contribute to seismic hazard analysis and earthquake engineering in Australia.
