On September 19 occurred the eruption of a volcano located in Cumbre Vieja, island of La Palma, Canary Islands, Spain. This is a geological event foreseen due to the continuous tremors that had hit the Island of La Palma in recent weeks.

The eruption of this volcano has caused the evacuation of thousands of people who have had to leave their boxes and possessions to the fate of the volcano. It is not yet known when the eruption will end or how much magma will move to the surface from the Earth’s interior.

Satellite recording the eruption

The Meteosat-11 satellite was launched in 2015 and its lifespan will end in 2033. In 2018, I replaced the Meteosat-10 satellite. It is a meteorological satellite that collects data and saves images every day and is geostationary, that is, it orbits over the Earth’s Equator line at the speed that the Earth does.

The eruption of a volcano is an impressive geological phenomenon. The earth is a flow of molten materials under our  feet. Images from the  Meteosat-11 satellite showed images and video inRGBcolour compositions from 19 and 20 September. These data show a higher concentration of SO_2 emitted by the volcano in the hours following the eruption.

Real-time images to follow the event

EUROMET also allows you to view real-time images of what is happening from the EUMETView (Real-time images)address. You can  zoom in on the island of La Palma and then add a layer showing the ashes. This layer is called  Geostationary Ring Ash RGB. The visualizations are made up of images from various  geo-stationed satellites. In Fig. 2 you can see a green cloud of ash coming out of the new Cumbre Vieja volcano
