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).

Every satellite in the sky, live on a spinning globe — all 14,000 of them. Satellite Tracker draws the whole catalog moving in real time: Starlink's woven shells, the GPS constellations, the ISS and Tiangong, spent rocket stages and tumbling debris. Filter by constellation or by nation, crank time to 600× and watch low orbits swirl while the geostationary ring hangs still. TONIGHT'S SKY See which satellites you can watch with your own eyes tonight — sunlit passes over your location, with rise direction, peak height and duration. Get an alert 10 minutes before, walk outside, look up. POINT YOUR PHONE AT IT AR mode draws satellites on your real sky. Pick the ISS, follow the arrow, and the station is right where your camera points. EVERY SATELLITE HAS A STORY Tap any dot for altitude, speed, period, inclination and its full orbit ring. Search 14,000 objects by name. Share any satellite with a friend. Works fully offline with a bundled catalog; live orbital elements when connected.
