The #Volcanic Isles . A brief history of volcanism across The British Isles.

Quite pleased with how this one turned out.

Location of volcanoes taken from wikipedia (spotted a mistake and got to make an edit to wikipedia in the process); fault lines from the #BGS 625k bedrock dataset and the IE GSI 500k Bedrock Geology for Ireland. Font: League-Spartan by the League of Moveable Type.

#requests, #pandas and #geopandas for scraping and wrangling.#scipy for making the proximity surface (that's the colour scheme), #matplotlib for plotting. With all labeling done manually in #inkscape.

EDIT: I've been kindly and helpfully informed that (a) Ben Nevis' age is closer to 399 Ma; (b) some are missing; (c) others perhaps shouldn't be there; (d) it's complicated. So, maybe don't use this map to make any strategic decisions.

"HIGHLIGHTS:
• [They] mapped channels and fossae within the volcanic plains east of Olympus Mons.
• Late Amazonian channels east of Olympus Mons formed by eruptions of lava or water.
• Fossae morphologies correspond to episodes of magmatic dike and sill emplacement.
• Loading of Olympus Mons may control magmatic ascent processes and eruption types..."
