The 2004 Indian Ocean tsunami caused by the Great Sumatra-Andaman earthquake was the first natural calamity that covered such large areas in modern times.
Since the 2004 great Indian Ocean tsunami that claimed a quarter of a million lives, other tsunamis in Java (2006), Sumatra (2010) and Japan (2011) have re-emphasized the need for a better understanding of such devastating events.
EOS research in that field is concerned with past tsunamis study (paleo-seismology, paleo-tsunamis sedimentary records, post-tsunami surveys) as well as plausible future tsunami modelling (tsunami effects in specific environments, tsunami flow modelling) and evacuation planning for cities threatened by a likely tsunami on short to medium-term.
The overall objective of EOS is to increase fundamental knowledge on tsunamis (generation, propagation offshore and inland), and to assess tsunami hazard in Southeast Asia, which gives input to the authorities to prepare for and to mitigate this inescapable risk.
Tsunami deposits contain a record of past tsunamis. As tsunami deposits are formed by tsunami flows carrying both offshore and near-shore sediments, the characteristics of tsunami deposits are indicative of the characteristics of tsunami flows....
