Summary

Between 5–9 January 1998 a severe ice storm struck parts of northeastern USA and southeastern Canada — especially Quebec, causing massive ice accumulations on transmission towers and wooden utility poles. :contentReference[oaicite:28]{index=28}
The storm destroyed over 1,000 transmission towers and more than 35,000 utility poles, leading to widespread and prolonged blackouts affecting millions of customers — power lost for days to weeks in many areas. :contentReference[oaicite:29]{index=29}

Systemic Features

  • Infrastructure not designed for severe compound weather stress (heavy ice + wind) — exposed structural vulnerability of power distribution in cold climates under extreme weather. :contentReference[oaicite:30]{index=30}
  • High interdependency of modern services: power, heat, communication all went down together — revealing how tightly coupled urban/rural systems are, and how a weather shock cascades across multiple critical infrastructures. :contentReference[oaicite:31]{index=31}
  • In many areas, lack of redundancy or alternative supply routes — once main lines collapsed, large populations were left without electricity, heat, or communications for extended periods. :contentReference[oaicite:32]{index=32}

Impacts

  • Millions of people without electricity, heat and essential services — widespread hardship, especially during freezing weather. :contentReference[oaicite:33]{index=33}
  • Severe damage to power infrastructure — towers and poles destroyed, requiring massive repair and replacement efforts; long recovery times for many rural and suburban communities. :contentReference[oaicite:34]{index=34}
  • Broad socio-economic disruption: loss of heat and power meant heating failures, food spoilage, business closures, communication breakdowns; secondary effects included property damages, health risks from cold and lack of heat, economic losses. :contentReference[oaicite:35]{index=35}
  • Highlighted the susceptibility of modern societies to extreme weather events and the importance of resilient design, redundancy, and emergency planning for climate-driven risks.
