News from La Palma: Canary Islands volcano shows no sign of stopping – new satellite images | World

Incredible ground footage showed a large column of superheated ash and gas gushing out of Cumbre Vieja on the Canary Islands. At the same time, incredible satellite images revealed an ox-eye cloud formation over the island.

Known as temperature inversion, this rare phenomenon is caused by a temporary high layer of hot air acting as a cover – trapping the volcano plume in the troposphere.
Normally, a volcano’s eruption plume rises directly into the stratosphere – the second layer of the atmosphere, which extends about six to 19 kilometers above the Earth’s surface.

In the case of La Palma, the hot air and ash struck a layer of hot, dry air that swept across the Sahara.

This air acted as a cover, preventing the plume from rising further and forcing it outward – creating eddies about 3.3 miles above the Earth’s surface.

It was hoped that this would end in a few days – and that people could start returning home soon after.
Unfortunately, that did not happen and the current situation looks increasingly unlikely to change in the immediate future.

Writing on Twitter, Maxar said: “The lava forms a huge delta on the coast of La Palma and has claimed around 98 acres (40 hectares) of new land from the Atlantic Ocean. “

The Canary Islands Institute of Volcanology (Involcan) yesterday shared terrifying footage of the ground capturing a rapid flow of scorching lava passing abandoned buildings.

“One of our teams was able to film a real lava ‘tsunami’ today,” Involcan tweeted.

“Impressive speed and overflow of the lava channel. “

The volcano erupted on September 19 – more than 50 years after its last activity.

This is not surprising after geologists detected more than 20,000 mild earthquakes in the weeks leading up to the eruption.
