Active Tectonics of the Andes (ATA) active fault database now on GitHub

In order to facilitate collaboration in development of the Active Tectonics of the Andes (ATA), a database of active faults in the (northern, for now) Andes, we have hosted it on GitHub.  The development version is here, although the ‘release’ versions will continue to be posted on the KU HawkDrive, as before.  We have received some comments about incompleteness of the 1.0 version in certain areas (such as around Quito, Ecuador), and we used that information to expand the database in those areas.  The database is now at the 1.1 version, as well.  All New and Improved!

I would also happily field other requests for improvements in the database both geological (such as about specific faults or regions) and technical (new file formats, etc.).  Please, don’t hold back!  This is a free, public, open-source project and the more minds we have working on it, the better the database will be.  And as this database improves, so does knowledge of structures responsible for seismic hazard to communities in South America.

Active Tectonics of the Andes (ATA-1.0): A new open-source active fault database, and interpretation

The 1 October 2012 issue of GSA Today (a science and news magazine by the Geological Society of America) features a new article from our research group, primarily written by my friend and colleague Gabriel Veloza.  There are two contributions in this paper: the first is an open-source active fault database called Active Tectonics of the Andes, or ATA-1.0, and the second is an overview of northern Andean tectonics and an interpretation of the overall fault kinematics as resulting from variably-oblique subduction.
