“…Many studies on tsunami modeling, as well as hazard analyses, have been addressed in western Indonesia, particularly in western Sumatra and southern Java [9, 10, 11, 12, and 13]. Field investigations of paleo-tsunami have also been carried out to indicate prehistoric tsunami occurrences [14,15]. In eastern Indonesia, earthquake-induced tsunamis are more frequent in occurrence and may be more hazardous with a potentially higher runup [16,17]).…”

Indonesia is situated at the conjunction of four major plates: Eurasia, India-Australia, the Pacific, and the Philippine Sea. Therefore, Indonesia is exposed to a considerable threat from natural hazards every day. Tectonic-related marine geohazards, particularly earthquakes-generated tsunamis periodically affect Indonesia, causing great loss of life and extensive damage to property and infrastructure in coastal areas. Many studies on tsunami modeling have been addressed in western Indonesia. In eastern Indonesia tsunamis, however, are even more frequent in occurrence and may be more hazardous, there is a lack of study and less attention. The Flores Back Arc Thrust (FBAT) is an active fault that lies on the sea floor of the Flores Sea in the north of Flores Island, extending from north of Bali to the east that may be connected to the Wetar thrust at the north of Wetar Island in the western Banda Sea. The FBAT is a source of seismicity in this area. From 1900 to 2022, there were 79 earthquakes with a magnitude of more than 6.0 Mw, and 11 of them generated tsunamis, and the most devastating one was the 1992 Flores earthquake tsunami. This study presents an estimated FBAT-induced future earthquake-generated tsunami runup based on numerical modeling.

This review summarizes geochemical studies in tsunami deposit research. The geochemical characteristics and behavior of tsunami deposits are described, and future research issues are identified and discussed. As geochemical approaches have focused on traces of seawater inflow or environmental changes rather than tsunami deposits themselves, such approaches are expected to contribute to (1) identifying tsunami deposits from geological layers, and (2) reconstructing tsunami inundation areas with high accuracy. After recent giant tsunamis, many geochemical characteristics of tsunami deposits have been reported, and the behaviors of various geochemical proxies have been gradually clarified. However, the usefulness of these proxies and their behaviors in different depositional environments remain poorly understood. In the future, it will be necessary to better understand the geochemical characteristics of both modern and paleo tsunami deposits and to develop and apply new proxies and analytical methods. Collaboration with other research fields will prove indispensable for these purposes; therefore, cross-disciplinary research should be promoted.
