How does Iya Volcano threaten coastal population in Sawu Sea, Indonesia?

To assess the potential threats posed by possible landslide-induced tsunamis in Sawu Sea, triggered by Iya volcano's activity, a thorough investigation should be carried out. This active volcano is situated in the southernmost part of Ende, East Nusa Tenggara Province in Indonesia. This volcano faces three densely populated islands: Ende, Timur, and Sumba. The mechanism formed the crater in south part of the edifice is still unknown, but the great explosion in 1969 has the potential answer. The explosion released tons of material and possibly triggered the instability on the edifice and generate tsunamis in Sawu sea. The tsunami generation will be modelled using the finite element method, which will solve the Navier-Stokes equation for incompressible flows in a multi-material simulation. A tool which is so-called Fluidity will be used in this project. The expected results of this study include the physical characteristics of the tsunami, such as the potential run-out distance, run-up height, and arrival time on nearby islands. Moreover, the study will include an exposure analysis to aid authorized institutions and local governments in risk mitigation.
