The final goal of the on-going three-years project is to develop a process-based, coupled hydrodynamic and morphological model for simulating sediment transport and deposit under tsunami waves.

To better understand the earthquakes and associated tectonic setting and ground shaking, we propose to study earthquakes in Southeast Asia, the most seismically active region on the earth, with a s

Rupture durations and other physical processes of tsunami earthquakes show strong variations and the underlying mechanisms of both earthquake and tsunami generations have not been understood.

Our knowledge of past sea-level change is largely relying on high-precision uranium/thorium disequilibrium dating on fossil corals.

The marine geophysical data collected during the 2015 MEGA-TERA expedition provide a unique window into the near-trench structure of the Sumatran accretionary wedge.

This webinar was part of the preparations for the Subduction Zone Observatory workshop held on 29 September to 1 October 2016 at the Boise Centre in Boise, Idaho, USA.

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.

Agung Volcano is currently erupting.

After over one month of intense seismic activity, during which the alert level at Agung was 4 (the highest), on 29 October 2017, at 4:00pm local time, the alert level was lowered to 3 (eruption imminent). This was due to a strong decrease in the number of earthquakes surrounding Agung, as well as a reduction in the seismic energy and amplitude of these quakes.
