Interactive Disaster Map: Simulate Any Catastrophe
DisasterMap is a physics-based interactive disaster simulator for earthquakes, tsunamis, asteroid impacts, and nuclear detonations. Built on real NASADEM elevation, GEM fault data, and published scaling laws. Click anywhere on Earth to run a scenario.
Launch the interactive simulator →The only disaster simulator that models all four
Most disaster simulators focus on a single phenomenon. DisasterMap covers four in one interactive environment, on a single shared map. Model an earthquake and see the tsunami it generates propagate. Simulate an asteroid airburst and see the thermal radius overlap with nearby nuclear reactors from the GEM Nuclear Power Tracker. Plan realistic worst-case scenarios that chain events the way real catastrophes do.
The earthquake model uses USGS ShakeMap methodology for MMI (Modified Mercalli Intensity) rings, calibrated against historical events like Tohoku 2011 and Valdivia 1960. Tsunami propagation uses empirical attenuation formulas tuned against observational wave-height data. Asteroid impact calculations follow the Collins-Melosh-Marcus scaling laws used in NASA and ESA impact assessment.
Real elevation, real geology
Flood modeling is only as good as the elevation data behind it. DisasterMap uses NASADEM for land and GEBCO for ocean/polar coverage, delivered through Cloud Optimized GeoTIFFs for fast tile streaming. When you simulate a tsunami inundation or sea-level-rise scenario, you’re seeing actual terrain, not a simplified approximation. Coastal cities, river valleys, low-lying polders — the map distinguishes them correctly because it’s reading real DEM data.
Pro users get the GEM Active Faults overlay: 16,195 mapped faults worldwide, color-coded by fault type (reverse, normal, strike-slip). Essential for realistic earthquake scenario planning — you can’t just drop an M9 anywhere and expect a sensible answer. Faults have strike, dip, and mechanism, and DisasterMap respects that.
Built for preppers, researchers, and the curious
DisasterMap isn’t a research-grade GIS package — those cost tens of thousands per seat. It’s an interactive disaster map for the people who actually want to think about worst-case scenarios: emergency planners verifying evacuation assumptions, preppers modeling their local fault exposure, researchers building classroom material, journalists illustrating historical events, and the incurably curious who just want to know what would happen if Yellowstone went full VEI 8 tomorrow.
Frequently asked questions
What disasters can I simulate?
Earthquakes with accurate MMI (Modified Mercalli Intensity) ring calibration and liquefaction radius modeling, tsunamis with hardcoded historical presets (Tohoku 2011, Indian Ocean 2004, Valdivia 1960, Cascadia) plus custom scenarios, asteroid impacts with real scaling laws for any size and angle, and nuclear detonations with accurate blast and thermal rings based on yield. Click anywhere on Earth to run any scenario.
Is the modeling scientifically accurate?
The simulations use published scientific formulas. Earthquake intensity follows USGS ShakeMap methodology. Flood modeling uses real NASADEM and GEBCO elevation data with hydrologically-aware flood tiles. Asteroid calculations follow Collins-Melosh-Marcus impact scaling. Nuclear effects follow Glasstone & Dolan yield curves. It's not peer-reviewed research, but every parameter is traceable to a primary source.
What are the GEM Active Faults and Nuclear Power Tracker overlays?
Pro users get access to the GEM (Global Earthquake Model) Active Faults overlay — 16,195 mapped faults color-coded by type (reverse, normal, strike-slip) — and the GEM Nuclear Power Tracker with enriched popups showing reactor type, capacity, and operational status for every nuclear facility on Earth. Essential for realistic scenario planning.
Can I share or export scenarios?
Pro users can generate shareable scenario links (fly-to coordinate + parameters) and export scenario data. Cataclysm pole-shift simulations with wind modeling and post-flip markers are also Pro-only, built for the alternative history and cataclysm research community.
How does pricing work?
Free access covers impact diameters up to 5,000m and nuclear yields up to 1Mt — enough for most scenarios. Pro is $15.99/year or $29.99 lifetime for unlimited scales, all overlays, and export. Or get the SimulationMaps All-Access bundle ($79 lifetime) for Pro across every map in the suite.
$79 once. Every map. Forever.
DisasterMap Pro alone is $29.99 lifetime. For $49 more, get Pro on every map in the suite — volcanoes, asteroids, shipwrecks, UFOs, climate — plus every new map we ship next.
