The minor volcanic forms associated with water-lava interaction, denominated in the literature as the hydromagmatic toaster, pseudo-craters or littoral cones, are small mounds built by lava fragments are arranged on the surface of many lava flows. It is ungrounded constructions of plan and elevation varied, whose spatial distribution appears to be associated to the path of the various units of a melt flow and the geometry of the different lobes of lava. In the Canary Islands are linked to the emplacement of lava flows in littorals environments.
