Interactive 3D
Earthquake & volcano simulators
The numbers behind earthquakes and eruptions are hard to picture — a magnitude 7 is 32 times a 6, a VEI 6 is a thousand times a VEI 3. These real-time 3D models let you move the sliders and watch the difference for yourself.
Earthquake simulator
Set the magnitude and depth, then watch P-waves and S-waves radiate outward and a city shake — with live energy, intensity and rupture-length read-outs.
Open simulatorEruption simulator
Dial the Volcanic Explosivity Index from a gentle lava flow to a super-eruption and watch the ash column climb — with plume height, ejecta volume and real examples.
Open simulatorThese models are illustrative — they use standard seismology and volcanology relations to convey realistic scaling, not to issue forecasts. For real monitoring see the live map and the eruption forecast model.
