The ASCE – Technical Council on Lifeline Earthquake Engineering (TCLEE) recently returned from a field trip (June 2011) to investigate lifeline performance in the Tohoku Japan March 2011 earthquake. The team was led by Curt Edwards, supported by Alex Tang, Leon Kempner, Yumei Wang, Alison Pyrch, Mark Yashinsky, John Eidinger and Alexis Kwasinski.

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 (free), covering: power, water, wastewater, highways, railways, telecommunications, liquid fuels, fire following earthquake / tsunami, as well as geology and geotechnical issues that affect all; as well as examples of tsunami vertical evacuation structures. It can be downloaded from:
