A new study by an international team of scientists found lockdown measures to stop the spread of COVID-19 led to a 50 per cent reduction in seismic noise around the world. The researchers, including Meghan Miller and Louis Moresi from ANU analysed datasets from over 300 seismic stations.

How we built a simple dashboard using Github actions with open source software and openly available (FAIR) data.

Meghan S. Miller, Australian National University and Louis Moresi, Australian National University Our responses to the COVID-19 pandemic have dramatically changed human activity all over the world. People are working from home, schools are closed in many places, travel is restricted, and in some cases only essential shops and businesses are open. Scientists see signs of these changes wherever they look.

The Underworld team would like to congratulate Bénédicte Cenki-Tok and co-authors at the University of Sydney and the University of Montpellier on their recent publication, B. Cenki-Tok, P.F. Rey, D. Arcay;

We built a cheap-and-cheerful solution with persistent storage and a binder-like access to notebooks in a repository that is aimed at serving a single classroom. The zero-to-server time is just a few minutes and there is minimal manual configuration.

The Underworld 2.9 release is available from Github, as a docker container and via zenodo (doi:10.5281/zenodo.3964957) it is also available through pip install for the first time (see below).Underworld paper in the Journal of Open Source Software The paper of record for underworld 2 has been published.

As the old truism states, the best way to learn is by doing. This is terribly unhelpful since, really, you can't 'do' anything until you learn. This is a Catch-22 that every grad student encounters; doubly so when it comes to anything involving code, where daily life provides very little in the way of intuition. Unlike other geodynamic modelling software, Underworld is designed to be approached with code.

How we added an auto-updating set of citations to underworld in our publications webpage. We need to curate all the publications that we can find that use the underworld geodynamics code and provide this information on our website.

-------------------------------------------------------------------------------- Version 2.8 of Underworld has been released recently. As with all major releases, this release brings numerous new features, enhancements and bug fixes. A summary of changes may be found within the usual CHANGES.md [https://github.com/underworldcode/underworld2/blob/v2.8.0b/CHANGES.md] file.

Viscoelastic materials exhibit the properies of both solids and liquids, with deformation rates dependent on both the viscous stress and elastic stress rate.
