Tohoku, Japan, Earthquake and Tsunami of 2011: Lifeline Performance
Damage was extensive… coal, oil and gas-power plants, wastewater treatment plants, substations, water transmission and distribution pipelines, highways, penstocks, telecom, all had various forms of tsunami and shaking damage. Some mitigation measures worked well; others not so much. Rapid response was much improved as compared to Kobe 1995. A 60-page presentation is available for download, […]
