A Decade of Monitoring and Research on the San Andrés Megalandslide on El Hierro, Canary Islands, Spain

Popis výsledku v původním jazyce

Precise 3D dilatometric monitoring began on the San Andrés megalandslide detachment plane on El Hierro, Canary Islands, during the winter of 2013. It has been found that this presumably aborted giant landslide creeps progressively at rates of up to 0.5 mm a−1, with accelerations following periods of seismicity and extreme rainfall. In addition, a detailed multidisciplinary investigation of the landslide detachment plane has found that silica and cataclastic layers were produced during a pair of discrete slip events at 545–430 ka and 183–52 ka. Furthermore, slope stability analysis has suggested that creep may result from the deformation of sedimentary layers in the ocean, while destabilisation of the volcanic flank would require an earthquake with an intensity of at least VII. Finally, simple tsunami modelling based on conservative scenarios has shown that even a comparatively small event could have severe ramifications along the coasts of northwest Africa and southwest Europe.
