What is it about?

The submarine slope of the northeast end of Tenerife Island (the Anaga peninsula) contains many gullies deviating around small hills, while the slope of El Hierro in contrast still has volcanic structures and lacks such deep gullies. Assuming that the difference in local relief of the 6-8 Ma Anaga slope and the young (<1 Ma?) El Hierro slope is caused only by erosion and that the original local relief of Anaga was similar to that of El Hierro, this study sought to quantify the erosion. A surface was interpolated across the small hills around both submarine slope areas and relief relative to that interpolated surface was quantified. Accordingly, ~100 m of material on average was estimated to have been removed from Anaga's slope, suggesting modest long-term erosion rates roughly comparable with those of subaerial lowlands.
