Abstract

Cinder cones were produced by the main basaltic eruptive episodes during the last 1 Ma in Tenerife. The aim of this paper is to document the evolution of gully erosion on 43 dated cinder cones over time and determine whether age is a critical factor in the degradation level of volcanoes, independent of other factors. The methodology employed is based on geomorphological and morphometric analyses. Only 39.5% of the Tenerife volcanoes have gullies; nevertheless, more than 84.6% of the Pleistocene cones present gullies, compared to only 20% of the Holocene volcanoes. Therefore, the older volcanoes appear to have been more affected by torrential rains. Although the age of a volcano is an essential factor in the degree of erosion, other factors intervene as well
