[email protected] Abstract: Barrier islands are indicators of coastal resilience. Previous studies have proven that barrier islands are surprisingly resilient to extreme storm events. At present, little is known about barrier systems’ resilience to seismic events triggering tsunamis, co-seismic subsidence, and liquefaction. The objective of this study is, therefore, to investigate the morphological resilience of the barrier islands Citation: Meilianda, E.; Lavigne, F.; in responding to those secondary effects of seismic activity of the Sumatra–Andaman subduction Pradhan, B.; Wassmer, P.; Darusman, zone and the Great Sumatran Fault system.
