Volcanic rays: What does this phenomenon consist of?


The La Palma volcano erupted on September 19. Now, three weeks later, the activity continues to cause damage on the Isla Bonita, and already has doubled the volume of materials emitted by the last eruption on the island, that of the Teneguía volcano in 1971. The lava from the three lava flows of the La Palma volcano continues to flow slowly while seismic activity persists on the island and has so far affected 656 hectares and destroyed 1,458 buildings, according to information collected by Copernicus, the Union’s observation program European.

Although, among the different phenomena that the island of La Palma has experienced in these three weeks, one stands out that, according to experts, is common in eruptive processes: volcanic rays.

What are volcanic rays?

This Monday, October 11, a professional from the Volcanological Institute of the Canary Islands (Involcan) captured how lightning crossed the upper part of the active volcano, despite the distance and the great dark smoke emanating from the volcanic cone.

“The ash and pyroclasts released by the volcano are initially neutral, so they have no electrical charge”, they explain from Involcan. But, according to experts, the cause of these volcanic rays is the friction between the rocks ejected by the volcano, which are thrown at high speed, as they rub against each other and produce charges of electricity.

The cause of these volcanic rays is produced by friction between the rocks expelled by the volcano., which are thrown at high speed, rub against each other and produce charges of electricity.

Following this video, Involcan’s spokesperson, David Calvo, spoke at Radio Television Canaria, that this type of lightning occurs “in many volcanoes” and stressed that this Monday “several of them” were produced. But the presence of these does not affect the quality of the air.

In addition, the National Geographic Institute (IGN) recorded another video – which leads this information – in which three rays are seen on the volcano in just three seconds.

Between 27 and 35% of volcanic eruptions that occur in the world generate lightning, as reported by MeteoRed. This phenomenon, for the most part, are not visible, due to the high opacity caused by the intense smoke of the place.

In addition to the new north colada, there are two other languages, according to the Department of Homeland Security (DSN): the original one, which barely has lava input, and another located further south, which affects new constructions within the security perimeter.

In the last hours, the meteorological conditions have favored the improvement of air quality so that this Tuesday, October 12, the confinement decreed last Monday that affected 3,500 people could be lifted.
