Smithsonian GVP · Holocene catalog
Volcanoes
Map and list of Holocene volcanoes from the Smithsonian Global Volcanism Program. Default filter highlights the Ring of Fire corridor. This is a location catalog — not live eruption alerts or forecasts.
Provenance: Static snapshot in
data/volcanoes.json fetched from the GVP WFS Holocene layer. If the snapshot is missing, you will see an honest empty state — we never invent eruptions or alert levels.
