Five real-world scenarios modeled on documented tectonic settings: Tōhoku (subduction megathrust), Anatolian / Istanbul (transform), Merapi (stratovolcano), Cascadia (subduction), and Hawaii (hotspot shield). Pick a scenario, spend a fixed budget on housing, hospitals, schools, and engineering technologies (base isolation, tsunami walls, early-warning systems, lahar diversion). Run the simulation (a real disaster strikes) and the data tells you which decisions saved lives.

Sessions auto-log not yet live
Every attempt is scored on the spot, but the Sessions Sheet that would auto-log your attempts to your Google account isn't deployed yet. For now, screenshot your final score, grade, and budget used from the debrief into your engineering journal after each iteration. The auto-logging is on the way and will replace the manual step when it ships.
