During the Holocene volcanic activity on Cumbre Vieja has become concentrated along a north–south axis, which may reflect an incipient detachment fault under the volcano. During the 1949 eruption a 4 kilometres (2.5 mi) long normal fault developed along the crest of Cumbre Vieja; it has been inactive since then [ 1 ] and prior eruptions did ...
The Cumbre Vieja (Spanish pronunciation: [ˈkumbɾe ˈβjexa]; meaning "Old Summit") is an active volcanic ridge on the island of La Palma in the Canary Islands, Spain. [4] The spine of Cumbre Vieja trends in an approximate north–south direction, comprising the southern half of La Palma, with both summit ridge and flanks pockmarked by dozens of craters and cones.

The wave was caused by the massive underwater Storegga slide off Norway. The tsunami even washed over some of the Shetland Islands . Tsunamite (the deposits left by a tsunami) dating from this event can be found at various locations around the coastal areas of Scotland, and are also a tourist feature in the Montrose Basin , where there is a ...
La Palma is a Norwegian disaster drama miniseries inspired by the Cumbre Vieja tsunami hazard hypothesis and partially based on the 2021 Cumbre Vieja volcanic eruption. [1] [2] [3] The series, primarily filmed on the island of La Palma in the Canary Islands, [4] also includes scenes shot in Tenerife. [5]
An animation of the earthquake swarm from the start until 19 September. An earthquake swarm started under Cumbre Vieja on 11 September 2021. It slowly migrated to the surface, with earthquakes of up to around mb Lg magnitude 3.5, [24] [25] and more than 22,000 earthquakes were recorded in the space of a week. [26]
Buildings near the Cumbre Vieja eruption Prior to the Cumbre Vieja eruption on the island of La Palma on September 20, 2021, over 25,000 earthquakes were recorded starting on September 10. Since the 1971 Teneguía eruption, the volcano has remained very active, as since October 2017 until the 2021 eruption alone, nine earthquake swarms occurred.
Geologists Dr. Simon Day and Dr. Steven Neal Ward consider that a megatsunami could be generated during an eruption of Cumbre Vieja on the volcanic ocean island of La Palma, in the Canary Islands, Spain. [102] [103] Day and Ward hypothesize [102] [103] that if such an eruption causes the western flank to fail, a megatsunami could be generated.
A satellite picture of the Caldera de Taburiente. Barranco de las Angustias is in the upper right and Cumbre Nueva is in the upper left. (South is above and north is below.) The Caldera de Taburiente is a topographic depression about 10 km across, and in places the walls tower 2000 m over the caldera floor.
