Contributing to the GEM Global Active Faults Database

New guidelines for contribution to the GEM Global Active Faults Database have been published on GitHub. They are reproduced below.

The GEM GAF-DB is a public, open-data project and contribution is quite welcome.

The GEM GAF-DB is a compilation of a set of regional and global fault datasets; most of …

Mapping active faults for fault databases and seismic hazard analysis

Cross-posted from Rocks and Water.

I've had several conversations with geologists recently who are considering creating new active fault databases (or datasets). These geologists are all government scientists who are interested in both tectonics research and seismic hazard, and would like to make maintainable databases that suit both purposes and …

Plotting focal mechanism 'beachballs' in QGIS

One of the major annoyances of working in earthquake and tectonic sciences is the difficulty of browsing earthquake focal mechanism 'beachball' data, and plotting it in GIS. The typical way of displaying this data spatially is to use a script in Matlab (probably using bb.m), Python (using the fantastic …

A basic simulation of earthquake clustering

New GEM dataset of active faults in the Caribbean and Central America

The Global Active Faults project of the GEM Foundation aims to produce a globally complete, reasonably homogeneous dataset of active faults on the Earth's surface for seismic hazard assessment. While most deforming regions of the world have some publicly available active fault datasets that I can stitch together, there are …
