Choose your tectonic setting
You are the chief planner. Build a functional city — housing, hospitals, schools, power, commerce — while protecting it from the geology underneath. Each setting produces different hazards. The same building, with the same technology, can survive in one place and be destroyed in another. That's the science you're learning.
Budget: $1.5M • Goal: Save lives, keep critical infrastructure standing, spend wisely.
Cascadia Coast
A Pacific coastline above a subduction zone. The seafloor plate is diving beneath the continent. Stress is building.
- Megathrust earthquake (M9)
- Tsunami waves following the quake
- Liquefaction in soft sediment
San Andreas Crossing
A growing inland city crossed by a major strike-slip fault. Two plates are sliding past each other. The fault line is visible.
- Strike-slip earthquake (M7.8)
- Surface rupture along the fault
- Strong shaking citywide
Volcano Island
A volcanic island over a mantle hotspot. The active shield volcano dominates one side; prevailing winds carry ash the other way.
- Lava flows from the summit
- Ashfall downwind
- Small volcanic earthquakes
