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.
Humans are fabulous agents of geologic change. What do I mean by this? We reduce the height of mountains via mountaintop mining to obtain energy resources. We blast through a mountain to make a road cut, or tunnel. We make new lakes by building dams for hydroelectric power. Indeed, we humans are capable of changing the landscape or environment (or climate for that matter) at rates much faster than normal geologic processes.
