'5 As rock masses are constituted by a sequence of massive lava flows, scoriaceous and pyroclastic layers in uncertain proportions, it is expected that the equivalent Mohr-Coulomb parameters will correspond to intermediate values between the purely unweathered massive rocks and the purely pyroclastic massif.

[b]'Concerning this fact, three areas of special relevance have been highlighted for their potential risk of catastrophic landslides in the Canary Archipelago. 'Teide Stratovolcano' (Tenerife), with average slope gradient of 30 degrees, 'El Julan ' (El Hierro), with average slope gradient of 25 degrees and the 'Cumbre Vjeja Rift Zone' (La Palma), with average slope gradient of 25 degrees........ '[/b] cont.. 'All of them with slope heights higher than 1000m exhibit conditions of slope gradient that overcome the friction angle of their rock massifs and of low cohesion that became those areas as susceptible of suffering gigantic slides.

And check out the swarm!
You have to drag the map to the Canary Island region and then zoom in several times....it's crazy the amount showing!
