The Mentawai Gap–Tsunami Earthquake Risk Assessment is a joint project between Schmidt Ocean Institute, the Earth Observatory of Singapore, the Indonesian Institute of Sciences, and the Institut de Physique du Globe de Paris.
Different rainforest trees grow on an island called Siberut; one of four big islands of the Mentawai Archipelago located off the west coast of Sumatra, Indonesia. Katuka is what Mentawaians call one family of these dipterocarp trees. These trees have very hard wood and are widely used for construction and crafting.
This project aims to provide a new understanding of Indo-Pacific history post-1000 C.E. based on an enhanced understanding of the inter-relationship between natural environmental cycles and events, and social and political cycles and events.
