You can try the first discovery and the 3D controls now. Stella unlocks every stage.
Pin earthquakes and volcanoes on a globe and watch the plate boundaries appear. Then lift out the real terrain of the Mid-Atlantic Ridge, the Japan Trench, the Himalaya and the San Andreas Fault, run a clock of millions of years, and see seafloor born, sink, mountains grow and a fault snap back.
In the fifty years since 1976 there were 83,900 earthquakes of magnitude 5 or more. Pin each one onto the globe and the dots do not scatter: they gather onto narrow lines. Add the volcanoes and they trace the same lines. Each piece those lines mark off is a plate.
Hypocentres: USGS Earthquake (M5+, 1976–2025).
Layer earthquakes, then volcanoes, then boundaries, and watch the dots become lines. Find which lines Japan sits on.
