The Global Strain Rate Model steps up to v2.1

After processing 6705 velocities from position time-series and taking 15,710 velocities from 223 studies in the published literature (including 1143 velocities for China also especially analyzed for this project), the GEM Global Strain Rate Model project publishes today the first public release of their strain rate model.

This model has been built using global mesh with 145,086 deforming cells of 0.2┬░ (latitudinal) by 0.25┬░ (longitudinal) dimension covering the plate boundary zones, with the remaining cells covering 50 rigid plates and blocks. The model and data input are a tremendous improvement to the previous global strain rate model from 2004.

The model will be integral part of the OpenQuake Platform. Version 2.1 will also be available on the UNAVCO website, one of the project's partners.

To download the model, to learn more about the it and its developers, you can go on the web page on the GEM website page dedicated to this project.
