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

366 PATA Days 2024 have significant implications for understanding the seismic activity and tectonic behavior in this region. However, further studies and data collection would be necessary to confirm this hypothesis and fully understand the implications of such an extension. C O N C L U S I O N Through the integration of newly procured multibeam bathymetry and available seismic sections, we have successfully identified the Kalaotoa Fault. Multibeam bathymetry serves as a valuable dataset for mapping underwater structural features, including fault scarps, folding, and cross-cutting structures, as exemplified in the Kalaotoa Fault. The Kalaotoa Fault, as identified within the study area, exhibits two principal orientations: east-west and northwest-southeast. The structural features within the study area reveal strike-slip structures as integral components of the Kalaotoa Fault, and folding associated with the Florest Thrust.
