Abstract

The generation force of tsunami has been one of the important subjects within tsunami research and understanding the concept of tsunami generation can give insights about the propagation and inundation of a tsunami. For that purpose, this study has been utilizing peer literature reviews regarding tsunami hazard analysis compiled from CARI! search-engine system including publications that have been published in both International and Indonesian journals within the scope of Indonesian context. It is evident that one-third of the total research publication number specifically investigate the source setting of tsunami generation. Among those, Sunda Megathrust has become the most frequently investigated by researchers with 45.9% of tsunami generation publications due to its long, wide, and active tectonic area which stretched from North-western Sumatra until south of Bali Island. This has been followed by The Krakatau Volcano of The Sunda Strait by 18.9%, and the Palu-Koro fault in Sulawesi Island by 17.1%. Other tectonic sources capable of generating tsunamis in the eastern side of Indonesia and the intraplate fault are also studied, which accounts for the rest 18% of the tsunami generation force.
