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

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

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

Data are obtained from the air pollution website of Generalitat de Catalunya
