Volcanic eruption in Spain's La Palma declared over

 

Mount Cumbre Vieja ("Old Peak") is a national park located in la palma, Canaria Islands in the Atlantic Ocean where a mountain ranges from north to south of the island lies an active volcano of the same name.



The volcano is said to have erupted on the island's surface about 125,000 years ago (125 kiloannums) covering an area of 25 kilometers in its entirety. Violent eruptions have been recorded several times during the site of la palma island, occurring in the hun years of 1470, 1585, 1646, 1677, 1712, 1949, 1971, and most recently in September 2021.

Volcanic eruption in Spain's La Palma declared over

The eruption of La Cumbre Vieja volcano on the Spanish island of La Palma that destroyed hundreds of homes and farmland was declared over on Saturday. The volcano has erupted in the past three months. The announcement follows 10 days of low-level activity from a mountain mountain located on a small island, part of the Canary Islands located off the northwest coast of Africa.

There were no injuries or deaths directly from the eruption that began on September 19. However, the eruption destroyed 1,345 homes, mainly on the western side of La Palma, as well as schools, churches, health centers, and agricultural irrigation infrastructure. Dramatic footage from the first days of the eruption has been repeatedly aired on Spanish TV, showing a thick cloud of smoke blanketing the bell tower of a church before it collapses.

The eruption was the first since 1971 and was the longest on record. About 7,000 people have been evacuated from their homes. They were given a few minutes to pack things. Losses from the volcano could exceed $1 billion, according to regional officials.

Spanish Prime Minister Pedro Sanchez described the news as "the best Christmas present."We will continue to work together, all institutions, to relaunch the beautiful island of La Palma and repair the damage it has caused," Sanchez said on Twitter.

 

 

 

 

What is the history of cumbre vieja volcano?

La Palma is an oceanic volcanic island located in the Highlands of Africa and is now associated with Tenerife, the most active volcano in the Canary Islands. Since about 125,000 years ago (125 ka) eruptions on all seabeds at La Palma have been associated with Cumbre Vieja, with eruptions along 25 km of mountains.

Surveys of the submarine showed that Cumbre Vieja continued south of Punta de Fuencaliente ("hot source point"), but no volcanic activity associated with underwater expansion was observed. Detailed geological mapping shows that the distribution and orientation of vents and feeder dikes within the volcano has shifted from a triple rift system (typical of most volcanic sea islands) to a single north-south fissure.

It is hypothesized that this structural reorganization in response to the growing voltage pattern is associated with the development of possible detachment faults under the western side of the volcano.  Siebert (1984) points out that the failure was caused by the intrusion of parallel levees and sub-parallels into the gap.

This causes the sides to become too steep and this inevitably causes the structure of the volcano to become unstable to the point that catastrophic failures can occur.
