This document discusses the impacts of two major incidents, Buncefield and Eyjafjallajökull, on business continuity and crisis management. The Buncefield explosion in 2005 disrupted over 300 businesses and 3000 residents for an extended period. Eyjafjallajökull's 2010 volcanic eruption grounded flights across Europe for 6 days, costing the aviation industry $1.7 billion in losses. Both events highlighted the importance of business continuity plans and crisis preparedness. The document concludes that more severe or prolonged disasters could have profoundly worse implications, and organizations must use scenarios to improve resilience through learning from experiences.
