Monte Cumbre Vieja

La Palma

Stratovulcano · Spain · 2426 m

The caldera rim of the Taburiente volcano, which makes up the northern section of the island of La Palma, is seen here from a lava flow field on the southern volcano, Cumbre Vieja. Bejenado volcano (left center) is located on the southern edge of the breached Taburiente caldera. Cumbre Nueva Ridge (right) was formed by a large-scale collapse. Cumbre Vieja is the most recently active volcanic center on the island, with numerous cones and lava flows.

Sintesi geologica

The 47-km-long wedge-shaped island of La Palma, the NW-most of the Canary Islands, is composed of two large volcanic centers. The older northern one is cut by the steep-walled Caldera Taburiente, one of several massive collapse scarps produced by edifice failure to the SW. On the south, the younger Cumbre Vieja volcano is one of the most active in the Canaries. The elongated volcano dates back to about 125,000 years ago and is oriented N-S. Eruptions during the past 7,000 years have formed abundant cinder cones and craters along the axis, producing fissure-fed lava flows that descend steeply to the sea. Eruptions recorded since the 15th century have produced mild explosive activity and lava flows that damaged populated areas. The southern tip of the island is mantled by a broad lava field emplaced during the 1677-1678 eruption. Lava flows also reached the sea in 1585, 1646, 1712, 1949, 1971, and 2021.
