| Sumario: | Continous seismic reflection profiles from north and south slopes of Tenerife, Canary Islands, indicate tha t the slopes o f this island are d o m in ate d by g ra v ita tio n a l structures includin g slumps, catastrophic avalanches, debris flows and turbid ites. O n the n o rth slope th e p ro x im a l ends o f th e tw o massive avalanches display a ridge-valley morphology and the distal ends by overlapping fans. Included with the fans is a extensive fie ld o f exotic blocks . The ridge and valley m o rp h o lo g y is the results o f lo n g itu d in a l shears created by diferentia l movements. The south slope is made up o f tw o terrains, a n o rth one whose morphology is due to a massive avalanche modified by volcanic processes, and a south terrain whose morphology is the result of massive slumpping of a thick sequence of structurally weak volcanic ash and pyroclastic rocks. Both of these terrains are modified on their distal ends by reworking by southerly flowing Atlantic Deep water |
