Fun facts:
- Pūhāhonu is the largest volcano on Earth — but mostly underwater in the Pacific! Volume ~148,000 km³, nearly double Mauna Loa.
- Hawaii dominates with 5 of the top 20 — the Hawaiian hotspot has been active for tens of millions of years.
- Iceland has 3 entries — sitting on the Mid-Atlantic Ridge where tectonic plates pull apart.
- Most of the largest volcanoes are shield volcanoes, built by gentle lava flows over millions of years.
