Worldwide Volcanic Eruptions & Hazard Database (1500–2025)
Consolidated dataset of 13,659 volcanic eruption events across 215 active volcanoes in 50 countries, spanning 525 years (1500–2025). Each record includes geographic coordinates, eruption characteristics, volcanic explosivity index (VEI), eruption type, dominant rock composition, plume height, human impact metrics (fatalities, evacuations, economic damage), evidence methods, primary hazards, and modern monitoring instrumentation. ## Key Features - **215 volcanoes** across all continents and major tectonic settings (subduction zones, rift systems, hotspots, continental collision zones) - **25 data fields** per eruption event covering geology, geography, hazards, and human impact - **Volcanic Explosivity Index (VEI)** from 0 to 8 with realistic frequency distribution - **Temporal coverage** from 1500 to 2025 with era-appropriate evidence methods - **Hazard taxonomy**: lava flows, pyroclastic flows, lahars, tsunamis, ash fall, gas emissions, debris avalanches - **Monitoring evolution**: tracks shift from geological/written records to satellite, seismic, GPS, and InSAR monitoring ## Sources & Methodology Modeled on data patterns from the Smithsonian Institution Global Volcanism Program (GVP), NOAA National Centers for Environmental Information, USGS Volcano Hazards Program, and EM-DAT International Disaster Database. Volcano locations, types, and tectonic settings reflect real-world geological classifications. Eruption frequencies, VEI distributions, and impact correlations are calibrated against historical records. ## Use Cases - Geospatial analysis and volcanic risk mapping - Climate impact modeling (VEI ≥4 eruptions and stratospheric aerosol injection) - Natural disaster preparedness and evacuation planning - Insurance and actuarial risk assessment - Machine learning for eruption pattern recognition - Educational and research applications in volcanology
