Volcanic eruptions on the island of Tenerife tend to occur with a frequency of between 100-200 years. These eruptions are mostly monogenetic events from strombolian type cones situated in the mountainous areas in the north-west and north-east of the island. The numerous cones pictured here are all relatively young and represent the most recent volcanic activity on the North-West Rift zone of Tenerife. These eruptions tend to produce basaltic aa lavas which can travel several km downslope and localised scoriaceous pyroclastics close to the cones. Pahoeohoe lavas do occur but appear to be much less common than aa types. More evolved phonolitic eruptions, both lavas and explosive pyroclastics, tend to occur high up on the island, associated with the Teide complex, but are much less frequent than the monogenetic basaltic eruptions and there are no historical examples of evolved explosive eruptions.
