LANDSLIDE PROCESSES ON VOLCANIC EDIFICES IN THE NORTH-EASTERN PART OF THE ATLANTIC OCEAN

In the northeastern Atlantic there are (from south to north) archipelagoes of volcanic islands Cape Verde, Canary, Selvagens, Madeira and Azores. They were formed on oceanic crust in Miocene-Quaternary times. Analysis geological structure thirty leads conclusion that half them destroyed at different times course their evolution by catastrophic landslide processes. On some these such events have occurred more than once. caused tsunamis large masses adjacent parts ocean.
