Abstract
Eastern Indonesia suffers from significant tsunami hazards due to its complex tectonic setting characterized by several subduction zones, numerous active volcanoes, as well as submarine landslides. Following the two destructive tsunamis in Indonesia in 2018 in Palu and Sunda Strait, it has been urgent to address large tsunami hazards in this unique tsunamigenic zone. This presentation outlines the outcomes of an international collaborative project on “Building Earthquake and Tsunami Resilience in East Indonesia”, supported by the Royal Society (UK) for the period 2019-2023. The project brought together research teams from UK and Indonesia, working together towards safer communities from tsunamis and earthquakes. The project mapped and studied seismogenic and tsunamigenic zones in East Indonesia, modelled scenarios of potential future tsunamis, and developed community resilience to tsunamis. A marine seismic survey was conducted in August 2022 to obtain seismic and bathymetric data from the region. The project also studied several recent earthquakes and tsunamis in the region, including the 14th November 2019 Molucca Sea tsunami following an Mw 7.2 earthquake, the 16th of June 2021 tsunami following an Mw 5.9 earthquake, and the 2018 Palu earthquake and tsunamis. It is believed that this project has generated a large database for earthquake and tsunami resilience studies in East Indonesia, and will inspire future research works. This research is funded by The Royal Society (the United Kingdom), grant number CHL/R1/180173 and Lloyd’s Tercentenary Research Foundation, the Lighthill Risk Network, and the Lloyd’s Register Foundation.
