Tsunami is one of the deadliest disasters in the world. Tsunamis in Indonesia (TI) and Taiwan (TT) are now wide open in all research fields. The purpose of this study is to analyze a comparison of research related to TI and TT from 2013-2023. This study used bibliometric analysis with metadata collected from the Scopus database and visualized using VOSviewer and Biblioshiny-Bibliometrix. The findings of this study indicate that the trend of research related to TI is more consistently increasing linearly than research on TT from 2013-2023. Citation trends per year in TI and TT research vary depending on the popularity of research topics and the impact of publications. The most dominant trend keywords used are Tsunami, Indonesia, and Taiwan. The authors who contributed the most to TI research were Syamsidik and Wu TR in TT research. Indonesia and China are countries that contribute and collaborate a lot. The highest and most relevant sources in TI research are the IOP Conference Series Earth and Environmental Science and Terrestrial Atmospheric and Oceanic Sciences in TT research. Syiah Kuala University and National Central University are top TI and TT research affiliations. Based on the network visualization, there is a very close relationship between tsunamis and earthquakes. This research aims to demonstrate the popularity of writing about Taiwan's and Indonesia's tsunamis so that future research might demonstrate more advantages of this subject. Researchers can learn about the advantages and disadvantages of each subject and discover updates for additional research with the help of this article. Recommendations for future researchers are to conduct research related to tsunamis and earthquakes with in-depth studies because of the high potential for further research. © 2023, Tsunami Society.
