... These erosion basins typically have mountainous perimeters and lower-lying central areas, formed through processes like differential weathering and erosion. Within these basins, alluvial fans often form due to the accumulation of weathered layers and the presence of small streams [24,25]. However, the thickness of sediment layers in these alluvial fans is This study evaluates the prediction performance of N-V S models suggested in South Korea through residual analyses, using datasets acquired from the Busan region. ...

... Consequently, the estimation of uplift rates relies on changes in elevation and the depositional age of the marine terrace. Furthermore, spatial differences in uplift rates can be discerned by examining marine terraces formed around the same time but with varying elevations (Cucci and Cinti, 1998;Park et al., 2017;Lee and Park, 2020). Similarly, temporal disparities in uplift rates can be inferred by analyzing a series of marine terraces of different ages. ...

... Studies on river terraces have predominantly focused on the eastern mountainous regions, i.e., the Taebaeksan and Sobaeksan mountain ranges, to determine the degree of ground uplift (Kim and Shin, 2014;Lee, 2018;Park, 2020a, 2021). Similarly, research on coastal terraces has concentrated on the eastern coast, where ground uplift has been active, with minimal studies conducted on the western and southern coasts (Choi et al., 2008;Choi, 2016;Park et al., 2017Park et al., , 2018aPark, 2019, 2020b;Shin et al., 2022a). ...

... First, the definition of the main fault remains uncertain and controversial. Several studies conducted during the 1970s termed the main structural feature aligned with the NNW-SSE-striking incised valley the "Ulsan Fault" (e.g., Kim, 1973;Kim et al., 1976;Kang, 1979a and b), but several subsequent studies adopted the term "Ulsan Fault Zone" to describe the various mapped and inferred NNW-SSE-to N-S-striking fault strands in and around the incised valley (e.g., Ryoo et al., 2000Ryoo et al., , 2001Ryoo et al., , 2002Ryoo et al., , 2004Ryoo, 2009;Lee et al., 2018). However, Okada et al. (1998) used the term "Ulsan Fault System" to describe NNW-SSE-striking neotectonic reverse faults that were mapped along the western front of the mountain range. ...
