Resumen:
Geodiversity is considered the abiotic equivalent of biodiversity; it can be explained in three main felds such as scientifc,
educational, and tourism. In sixteen geosites of Napo Sumaco Geopark, a quantitative assessment of geodiversity was carried
out using the methodology proposed by Brilha (Brilha, Geoheritage 8:119–134, 2016). This work has a feld data collection
phase in the geosites Shunku Rumi and Pungarayacu Quarry, where for the frst time a geological sketch and stratigraphic
columns were made. Regarding the quantitative assessment, it was found that the geosites Sumaco Volcano and Guagua
Sumaco Lagoon and Outlook have a high scientifc value, the geosite Pungarayacu Quarry has a high potential for educa tional use, and the Puerto Misahualli’s Bookcase has a high potential touristic use. In terms of degradation risk assessment,
Pungarayacu Quarry and Hollin River geosites have a high and moderate degradation risk respectively. The remaining
fourteen geosites show a low risk of degradation because there are no activities that cause degradation, and are protected by
the people of communities and local guides. Finally, this work shows the need for more scientifc research, improvement in
the security conditions, promotion of the geosites, and development of didactic material
