Welcome to sulfure dioxide air pollution!

Cumbrevieja is a volcano located in la Palma island. It's an active volcano producing sulfur dioxide gases in the atmosphere.

The weekend 25 to 26 of September 2021 air pollution from the volcano arrive to Catalonia as you can see in the following graph.

The graph was created using matplotlib library using python and the code is below.

Data is obtained from the air polution website of Generalitat de Catalunya.
