Reassessment of the 1907 Sumatra "Tsunami Earthquake" Based on Macroseismic, Seismological, and Tsunami Observations, and Modeling

The Child of Krakatoa Awakes

At approximately 9:30pm local time (2:30pm GMT) on the 22 December 2018, a tsunami struck Indonesia’s Sunda Strait, which lies between the islands of Java and Sumatra, claiming over 430 lives. According to Indonesia’s disaster agency there are at least 1,500 injured, over 120 people still missing, and around 12,000 people have been displaced.

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.

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.
