Explore over 4,575 volcanoes across 118 countries with 11,000+ eruption records. VolcanoMap combines the Smithsonian Global Volcanism Program's definitive database with live weekly activity reports in one powerful app. INTERACTIVE MAP Color-coded pins show active, dormant, and extinct volcanoes worldwide. Filter by Active, Notable, or those with Photos. Combine filters with intuitive Venn diagram controls. Toggle the Ring of Fire and tectonic plate boundaries as map overlays. LIVE VOLCANIC ACTIVITY The Eruptions tab delivers the Smithsonian's weekly volcanic activity report directly to your phone. See which volcanoes are currently active worldwide, with full activity descriptions and one-tap navigation to details or the map. ERUPTION TIMELINE Every volcano's eruption history visualized as a color-coded bar chart using the Volcanic Explosivity Index (VEI). Over 11,000 eruption records spanning thousands of years. See the 50 most recent eruptions across all volcanoes in timeline or list view. VEI SCALE Each eruption is rated 0-8 on the Volcanic Explosivity Index, color-coded from green to dark red. Contextual comparisons explain the scale — from gentle Kilauea lava flows (VEI 0) to Tambora-scale super-colossal events (VEI 7).
