[S13-P-01] A web-platform benchmark for moment tensor inversion

Torsten Dahm, Sebastian Heimann, Simone Cesca (GFZ German Research Centre for Geosciences)

Moment tensor inversion is a powerful tool for the determination of the earthquake source parameters. Following extensive developments in the last two decades, global and regional moment tensor services are nowadays becoming a standard and a growing number of different moment tensor catalogs are provided to the community. In parallel, a wide range of software offering standard moment tensor tools are available to seismologists. However, moment tensor results are highly affected by data pre-processing, data selection and implemented methodologies. As a result, moment tensor catalogs often show systematic differences among source parameters. Thus, despite of the widespread diffusion of data and methods, moment tensor data mining faces new challenges. In response to these problematic, a IASPEI working group (WG) on routine moment tensor inversion was started, with the main aim of developing and implementing a benchmark and verification platform for moment tensor inversion procedures, and to provide recommendations for the scientific community. We present a preliminary web-based platform, where new moment tensor inversion methods can be tested and young researchers new to the field can find and use the benchmark to test their own developments over a broad range of applications. The platform provides access to ground truth events representative of a broad type of seismicity and monitoring conditions, including synthetic and real datasets.
