Summary

Hurricane Sandy caused major coastal flooding and storm surge in New York & New Jersey, collapsing energy, transport, and telecom networks simultaneously.

Systemic Features

  • Infrastructure design assumptions exceeded by climate-driven storm surge
  • Cascading dependency across energy → telecoms → hospitals → fuel logistics
  • Dense megacity environment amplified systemic disruption

Cascading Systems Affected

  • Subways, tunnels, bridges, road networks
  • Power grid (8 million customers lost power)
  • Water, sewage, pumping systems
  • Fuel distribution crisis caused by logistics and power failures

Impacts

  • 233 fatalities, widespread displacement
  • Billions in economic losses and long-term coastal adaptation policy changes
