“…The 2021 GEBCO gridded dataset is a global coverage of land and ocean elevation models with 15-arc second grid (∼455 m) horizontal resolution. It is included in this study for comparison as it is commonly used in tsunami modeling [2][3][4][5] . Because of the coarse resolution of GEBCO, it does not reflect the detailed shape of the coastline as seen on satellite images or high-resolution elevation models (Supplementary Fig.…”

“…In addition, tsunami models based on high resolution bathymetry have high computational processing requirements. Hence, publicly available datasets with wide coverage such as the General Bathymetric Chart of the Ocean (GEBCO, www.gebco.net), ETOPO (ncei.noaa.gov/maps/grid-extract/) and EMODnet (data.europa.eu/data/datasets) are commonly used for modeling tsunami propagation (e.g., GEBCO - [1][2][3][4][5] ; ETOPO - 6,7 ; EMODnet - 8,9 ). However, these datasets have coarse resolutions and are artificially smoothed (Marks and Smith, 2006).…”

We examined how variations in bathymetric resolution affect simulated coastal tsunamis. We used 1-m resolution LiDAR datasets to generate resampled bathymetries with 5, 10, 20, 30, 40, 50, 100, 200, and 300 m resolutions, and added GEBCO data in the comparison. Tsunami waves offshore were generated by setting up an instantaneous rupture sourced from a hypothetical fault model. We used the COMCOT software to model tsunami propagation towards the coas. Using the 5 m bathymetry as the reference model, we observed that datasets with 10 – 50 m resolutions can reproduce tsunamis reasonably well. The maximum heights are overestimated by ≤5% or underestimated by ≤10%, and the first wave arrival time is ∼10%earlier than expected. Coarser bathymetries show an increasing trend of height underestimation, with the GEBCO model underestimating it by as much as 70%. Coarser bathymetries have more variable first wave arrival time, either ≤20% later or ≤10% earlier. Overall, a reasonably accurate result can be achieved using a bathymetric resolution in the 10 m – 50 m range, and is achievable with reasonable computational efficiency. This study highlights the importance of shallow bathymetry in the numerical modeling of tsunami propagation.

“…and EMODnet (data.europa.eu/data/datasets) in assessing local tsunami hazards at the coast is very common in tsunami studies (e.g., GEBCO -Gunawan et al, 2019;Lee et al, 2021;Pribadi et al, 2018;Rikarda et al, 2020;Tatapu et al, 2021;Widiyantoro et al, 2020;ETOPO -Hou et al, 2020;Løvholt et al, 2019;EMODnet -Omira et al, 2022;Schambach et al, 2020). This is likely due to their broad coverage and public availability.…”

“…Moreover, using high-resolution bathymetry data in modeling requires significant computational processing time (e.g., Yamazaki et al, 2012).

would hit Mataram are higher and arrive earlier (∼1.6 -2.7 m high; <9 minutes) than the waves in Denpasar (∼0.6 -1.4 m high; <23 -27 minutes). I further explored the xv impact on Mataram and showed that the inundation could affect industrial sites, which in turn could trigger technological disasters, making the scenario more hazardous.Overall, this thesis addressed the sensitivity of tsunami models and tsunami energy to geologically constrained fault sources and shallow bathymetry. I hope that my contributions will help in the advancement of tsunami research and can be applied in future work.

The West Coast of Banten is one of the tsunami-affected areas in Indonesia. People living in this region have to be aware of the possible tsunami occurrence anytime. PUSGEN 2017 research result indicated that Megathrust of Sunda Strait has the potential to trigger an earthquake up to magnitude 8.8 generated in the seismic gap zone and strengthened the issue of tsunami threats. Therefore, we need a more detail study of these areas. In this study, we use the mathematical model of tsunamis from ComMIT software by NOAA and overlay it with the coastal population density. The outputs of ComMIT software are heights of run-up, inundation areas, and estimated time arrivals. The population density is determined by the housing population density method and the total number of populations divided by the area of settlements. The result is the number of people affected by tsunami obtained from the intersection between the area of inundation and the field of settlements. In Tanjung Lesung, there are up to 134 people affected by the tsunami.
