Massive slope instabilities
The continental slope of the Canary Islands volcanic province is characterized by the occurrence of several seamounts and large landslides that have been widely documented. A detailed morphological study of the Echo seamount has been done by using multibeam bathymetry, backscatter data and very high resolution seismic profiles. The seamount shape, the occurrence of a flat summit and the presence of characteristics morphological features on the summit and along the flanks as volcanic cones, ridges, slides scars, gullies and channels, among others, have allowed establishing differences in its evolution. The analysis of these seamount features let to think that the seamount could be an oceanic island that becomes eroded and sank to its present depth. Recent geological processes observed at the base of the seamount let to establish different features and morpho-sedimentary units. They have been interpreted as the result of dismantling processes of the flanks although they have also ...
