Sumatran Geodesy

Sumatran Tectonic Geodesy

We propose to investigate five aspects of the tectonic behaviour of the Sumatran section of the Sunda plate boundary, using Sumatran GPS Array (SuGAr) data.

What are the slip rates and locking depths of the Sumatran fault?
What is the behaviour of the megathrust updip of the great 2005 and 2007 ruptures?
What is the behaviour of the 100-km section of the megathrust between the 2004 and 2005 ruptures?
How is the Mentawai patch behaving now, prior to its anticipated great rupture? and
What are the long-term post-seismic responses to the recent great Sumatranruptures?
