Coastal regions are increasingly recognised as prime locations for recreational tourism. Among these, the province of Manabi, Ecuador, with its distinct coastal cliff geomorphology, has considerable tourist appeal. However, a major seismic event in 2016, registering Mw 7.8, resulted in significant geomorphological alterations at the coastal level. This study sought to characterise the geomorphology of beach-cliff systems in Manabi province, utilising Geographic Information Systems (GIS) to identify the geomorphological changes induced by the 2016 earthquake, with the objective of informing sustainable management strategies. GIS was employed to discern the geomorphological alterations in the beach-cliff systems and compute their retreat rates. A Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis facilitated understanding of the current state of the cliffs, critical for devising coastal and tourism management strategies. The study area encompassed the beach-cliff systems of Canoa,
