Description :
The present work addresses a long-term controversy concerning the origin of Orotava Valley, one of the most peculiar valleys in the Island of Tenerife. Analysis of the key features of Orotava Valley leads to formulation of an hypothesis which could be applicable to numerous volcanic areas. Such valleys are developed as volcanic valleys undergo lateral expansion due to repeated alternations of processes: initial erosion of the gorges by streams, the burial of the gorges by lava flows, and the inversion of the relief by erosion at the base of valley walls.
