Proceedings of the 12th International INQUA meeting on paleoseismology, active tectonic and archaeoseismology

Despite these historical records of damaging earthquakes of intensity VII-IX or more, there are no systematic active fault mapping and paleoseismological studies have been carried out for the epicentral region of these historical earthquakes. Most of the paleoseismological studies have been focused on the Yangsan-Ulsan fault system (Cheon et al., 2020; Gwon et al., 2021; Song et al., 2020; Kimand Seong, 2021; Naik et al., 2022; Kim et al., 2023, Naik et al., 2024) which may be due to the presence of clear fault morphology, better documentation of historical records, and presence of several nuclear facilities.
