The SuGAr, and tectonics of the Sumatra subduction zone
The SuGAr is a 60-station continuous GPS network designed to monitor tectonic processes along the Sumatra subduction zone. It was initiated in 2002 by Caltech, and is now maintained by EOS and LIPI (the Indonesian Institute of Sciences). We have added many new stations to the network since 2010.
The Sunda megathrust has generated a large number of earthquakes in the last decade, so this network has given us a lot to work on. Some highlights of the things we've been working on are below.
