How Strong are the Rocks in the Sumatran Subduction Zone?

The highly active Sumatran Subduction Zone has produced more than four great earthquakes in the last decade. The first of these was the giant Mw 9.2 Sumatra-Andaman earthquake that ruptured on 26 December 2004. This devastating event was followed by three others – the Mw 8.6 Nias-Simeulue quake in 2005, the Mw 8.4 Bengkulu earthquakes in 2007, and the Mw 7.7 Mentawai tsunami-earthquake in 2010.

We will use geodetic (GPS and InSAR) and geologic data to study magnitude, rates and sources of subsidence in locations around East and Southeast Asia that include Bangkok (Thailand), Jakarta and t
