See what an earthquake and a tsunami do to every building within one mile of the San Francisco Ferry Building, and what fixes would help. What it does Risk Engineer Argon is a web app that simulates a preset earthquake, followed by a tsunami or an extreme wave surge, across a one-mile district. Every building changes color and moves according to its own predicted damage. The sidebar lists the weak points by priority and cost. Pick one or more fixes, replay the simulation, and see the district do better.
