La Palma Volcano Eruption 2021

The Cumbre Vieja eruption of 2021 started on September 19, 2021, as a flank eruption at the Cumbre Vieja volcanic edge involving the southern portion of the Spanish island of La Palma in the Canary Islands. It has been the principal volcanic emission on the island since the eruption of Teneguía in 1971.

Reaction Of Australian Geologists

When he heard that La Palma’s well of lava had erupted, Matt Pankhurst geologist stacked his magnifying instrument into his vehicle and hustled to get a ship to the Spanish island.

Like different researchers all over the planet, he was anxious to get a direct glance at the uncommon and significant information pouring out of the Cumbre Vieja fountain of liquid magma off Africa’s northwest coast.

The Operational Land Imager

Landsat 8’s Operational Land Imager (OLI) captures this pair of natural color images to show how dramatically the areas of Todoque and El Paraíso have altered. On May 21, 2021, took the first photo. The second delivers the exact location as of December 15, 2021. The house is displayed as a small white rectangle. Many of the large white and gloomy rectangles are greenhouses for growing bananas. Dark debris of lava flows from the 1949 eruption, with the bottom third of both images cut out.

Staring Of An Eruption

Seismic action everything except halted around 9 pm neighborhood time on Monday, the Canary Islands Volcanology Institute, Involcan, said Tuesday. It’s the longest period without quakes since the explosion started.

“This doesn’t infer the emission is finishing, since on different events ends were trailed by a reestablished expansion in action,” Involcan tweeted.

It added a film of the Cumbre Vieja showing how the practically consistent thundering of the well of lava had stopped.


  • The lagging magma streams have made enormous measures of harm to homes, framework, and farmland.
  • A few regions that were not straightforwardly invaded by magma have been covered with debris.
  • A mid-December update indicates that the eruption has annihilated no less than 1,600 structures.
  • Magma has burned-through something like 12 square kilometers of land, including no less than 4 square kilometers of harvests.
  • Starting appraisals say that the emission has caused somewhere around 550 to 700 million euros in harm.
  • No wounds or passings have been straightforwardly connected to the explosion, and life has generally proceeded as typical on the more significant part of the island’s 80,000 inhabitants.
  • The main job of the island, banana manors, has been destroyed.

Evacuation of People

Thousands of individuals have been evacuated, and minimal 2,910 buildings have been destroyed since the eruption began on September 19. A volcanologist, Stavros Meletlidis, said there are some possible explanations at the National Geographic Institute.

Collective effort’

In a non-open house area at the foot of the smoking volcano, scientists collected lava samples with a metal rod when it was still hot and with a hammer when it was cold. The rock is then divided into smaller pieces that can send to colleagues worldwide for analysis. “It’s a joint effort,” Pankhurst said.

Following three months of enthusiastic magma streams and dangerous action, there are signs that the spurt might be finishing. On December 14, geologists with the Canary Islands Volcanology Institute (INVOLCAN) saw a sharp decrease in seismic action; touchy movement, sulfur dioxide outflows, and magma streams likewise faded. While action could get once more, ten days of inertia would incite neighborhood logical specialists to proclaim the emission over, as indicated by Canarian Weekly.

Earthquake multitude before the explosion:

On September 11, 2021, an earthquake began under Cumbre Vieja. It gradually moved to the surface, with quakes of up to around mbLg extent 3.5, and in excess of 22,000 seismic tremors were recorded over about seven days. A yellow caution of potential volcanic movement was given on September 13, covering 35,000 individuals in the districts of Los Llanos de Aridane, Fuencaliente, El Paso, and Villa de Mazo. Something like 40 people and some animals on La Palma was emptied by specialists because of this notice, albeit no total departure of the area around the spring of gushing lava had been announced.

Nature Cant be Ignored

As the population density rises, the government needs to prepare for a future volcanic crisis, Blanco said. Blanco has appeared frequently in the media for the past few weeks and has a friendly look in Spain. “We can’t live on our backs naturally, and we can’t forget that this is a volcanic archipelago, that eruptions have occurred in the past, and that they will continue,” she said. Since autumn, slow-flowing lava on the way to the Atlantic has covered more than 1,200 hectares of land, damaging the island’s two major industries: tourism and banana cultivation.

Magmas and Gases

“Magma needs the power to reach the surface, but it doesn’t seem to be there at this time,” said Meretridis, who said that if the eruption loses its power, this is due to a decrease in the volume of gas or magma. However, it can result from a blockage between an underground magma chamber and a surface duct, in which case the pressure rises to a critical mass, causing a new explosion.
