Welcome to sulfur 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 polution form 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 obtaiend from the air pollution website of Generalirar de Catalunya.
