What is it about?
In this comment, we complained of misreporting of our original article on the slump and also put forward some points of interest revealed by the dataset presented by Hildenbrand et al. Resurveys of points on and outside this area of southern Pico Island have revealed movements of pre-historic slump. These contrast with geophysical data from the rock platform in front of the slump, which show no evidence for movement over the Holocene. Reconciling these two sets of observations may require the slump to have only recently reactivated after being quiescent during the Holocene period of stable sea level.

Why is it important?
Collecting and analysing geophysical data on the rock platforms around active coastal slumps may reveal whether they have been significantly active in the late Holocene.
