Multi-risk assessment and cascading effects analysis conducted as part of a cooperation between Indonesia and Germany - Joint research on tsunamis induced by volcanoes and landslides.
Why do tsunamis still occur seemingly without warning? In 2018 alone, Indonesia experienced not one but two tsunamis that claimed numerous lives. Both tsunamis followed a chain (cascade) of events, with landslides triggering tsunamis. New detection and early warning strategies need to be developed for tsunami events like these. The TSUNAMI_RISK project therefore takes mapping and monitoring as its starting point, investigating the processes during landslides and the resulting tsunamigenic effects. In close cooperation with Indonesian partners, the project aims to identify unstable slopes; to measure mass movements with state-of-the-art satellite observations and geodetic and seismic methods; to investigate their dynamics in simulations and experiments; and thus to investigate their relevance and precursors in geoscientific and technical terms. The project will test the seismic detection of landslides, which can be used as a concrete early warning method; however, these signals are more subtle than those of tsunamigenic earthquakes, and the work planned for this project will help develop possible warning strategies for this class of events. Furthermore, TSUNAMI_RISK will explore how geoscientific findings can be used to inform societal discussions and disaster risk management in Indonesia. The work is carried out by thematically and methodologically leading working groups at German universities and Helmholtz institutes in close cooperation with Indonesian authorities and research groups.
