Hazard Sequence Simulator

Compound hazards, cascading effects and interrupted recovery
Interactive risk laboratory

See how hazards cluster, interact and interrupt recovery.

Generate transparent earthquake–aftershock–rainfall–landslide sequences, then compare the same event catalogue with and without resilience measures.

Run a simulation to play the sequence.
