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.
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.
Volcano profiles
Regions →Mount St. Helens
A Cascade Range stratovolcano in the Smithsonian Holocene snapshot, and the eruption USGS uses as a VEI 5 example.
Mount Rainier
The tallest volcano in the High Cascades group in this site’s Holocene snapshot, on the same subduction margin as Mount St. Helens.
Kīlauea
A hotspot shield volcano that many people place in the Ring of Fire, and that this site’s audited rectangles leave outside.
Mauna Loa
The second-tallest edifice in the Hawaiian-Emperor group in this snapshot, and another intraplate volcano outside the Ring of Fire boxes.
Fujisan (Mount Fuji)
Japan’s famous stratovolcano in the Holocene catalog, with a last-eruption year of 1708 and a corridor-box detail that is easy to miss.
Aira caldera (Sakurajima)
The Holocene catalog names this caldera Aira. News about frequent eruptions at the same place usually says Sakurajima.
Pinatubo
A Luzon arc stratovolcano whose 1991 eruption is the USGS example of VEI 6.
Taal
A low caldera in the Luzon Volcanic Arc, in the same country file as the much taller Pinatubo and Mayon.
Mayon
The tallest listed volcano in the Eastern Philippine Volcanic Arc in this snapshot, and a different subregion from Taal and Pinatubo.
Krakatau
A Sunda arc caldera in the Holocene catalog, listed at 285 m, beside much taller stratovolcanoes on the same arc.
Merapi
A frequently listed Sunda arc stratovolcano, set beside the low Krakatau caldera and Tambora’s row in the same subregion.
Popocatépetl
A Trans-Mexican Volcanic Arc stratovolcano complex whose catalog point sits in two of this site’s overlapping corridor boxes.
Cotopaxi
A Northern Andean stratovolcano in the Holocene catalog, on the same broad margin as several USGS great-earthquake epicenters.
Villarrica
A Southern Andean stratovolcano in the same South America rectangle as Cotopaxi, and in a different volcanic subregion.
Ruapehu
The tallest volcano in the Taupo Volcanic Arc in this snapshot, on the New Zealand side of the Ring of Fire boxes.
Shishaldin
The tallest listed volcano on the Aleutian Ridge in this snapshot, inside the Alaska rectangle and beside a trench known for great earthquakes.
