Land usage classification of La Palma before (August 2021) and after (November 2022) the volcanic eruption

These images illustrate the impact of the eruption on inhabitants of the island with the amount of crop land (seen in dark green on zoomed in image) and residential areas (seen in yellow on zoomed in image) consumed by the lava flow (seen in red). 7,000 people (8% of the total population) had to be relocated and 9 million euros in damage was caused by the volcanic event.
