Geosites assessment in a volcanic hotspot environment and its impact on geotourism, Santa Cruz-Galapagos Islands, Ecuador

Abstract

Volcanic environments offer a unique combination for life development. UNESCO recognized the Galapagos Islands as Natural World Heritage site due to the uniqueness of flora and fauna. In addition, they have relevant geological value because of their volcanic origin associated with a “hotspot” and still evolving geological dynamics. This study aimed to evaluate the geological heritage of Santa Cruz Island by identifying and valuing geosites, considering the scientific, academic, and tourist fields, and the risk of degradation to establish geoheritage management strategies. This study applied four semi-quantitative assessment methodologies and SWOT analysis to identify 15 geosites related to volcanic hotspots, particularly volcanic craters, cracks, beaches, lava tunnels, lagoons, and volcanic depositional landforms. Due to the uniqueness of their geological characteristics, the valuations applied reflect “very high” and “high-medium” qualifications in the geosites. Their identification and valuation allowed for establishing protection, geo-education, and sustainable use strategies (geotourism). In addition, the study identified a research opportunity associated with the cultural value of geosites of volcanic environments within protected areas with singular ecological value.
