The Resilience Test: Tsunami Drill

New tsunami evacuation signs are appearing along the Portuguese coast. Behind them sits an entire machine: sensors, warning centres, sirens, and a national drill held every November. This episode looks at how that machine actually works, and where it stops working. Why the most dangerous wave would arrive in fifteen minutes, before any siren can help. Why Indonesia's warning system existed on paper and still failed. What a ten-hour blackout revealed about the part of resilience nobody builds. And what the schoolchildren of one Japanese city proved about the difference between having a plan and being ready.First episode of Resilience, a new series about what keeps a society standing when the unexpected arrives.
