Sediment transport processes under tsunami waves – a case study of tsunami deposits in a coastal cave in Aceh, Sumatra

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

Southeast Asia and Global Seismology

To better understand the earthquakes and associated tectonic setting and ground shaking, we study earthquakes in Southeast Asia, the most seismically active region on the earth.

Late Quaternary palaeoenvironments of the Kallang River Basin, Singapore

We plan a reconstruction of late Quaternary environmental history of the Kallang basin, southern Singapore.

A comparative study of Late Quaternary hydroclimate from marine sediments from offshore Singapore

We plan a comparative study to test the feasibility of reconstructing hydroclimate and temperature variability during the past (MIS 5e) and current (Holocene) interglacials from marine sediment cor

Investigating the geomicrobiology of storm and tsunami deposits

We propose using geomicrobiology to overcome the primary issue in documenting prehistorical coastal hazards which is the faint distinction between storm and tsunami deposited sediments.

Characterizing coral open-system behavior by high-precision U/Th dating: a case study in Sumba Island, Indonesia

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

Structural geology and hazards of the Sumatran accretionary wedge

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.

Biogeochemistry of barium in rivers and oceans of SE Asia

The primary objective of this project is to measure Ba and Ba isotopes in the river waters and oceans of Southeast Asia in order to characterize and also understand the potential of using Ba isotop

The Sumatran and Java subduction zones, scientific questions and emerging science opportunities

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.
