When the Seventh U.S.-Japan Workshop was held in Seattle, Washington, a
devastating earthquake occurred in western Turkey, near Izinit, an industrial city of
about 1 million people, approximately 90 km southeast of Istanbul. The 7.4 magnitude
earthquake resulted in tens of thousands of deaths and serious injuries, destroyed
thousands of buildings, incapacitated water delivery and electric power systems, caused a
catastrophic fire at an oil refinery, and led to the failure of sea walls with serious
flooding of waterfront developments. Participants of the workshop were among the first to
be dispatched in U.S. and Japanese reconnaissance teams to the earthquake-stricken area.
The earthquake in Turkey is a sobering reminder of the importance of the workshop topics
and the need to transfer lessons learned from earthquake experience into engineering
The Seventh US-Japan Workshop was a forum for Japanese and U.S.
colleagues to share their ideas about earthquake damage to lifelines and explore advanced
technologies for characterizing liquefaction, stabilizing hazardous sites, and improving
post earthquake response and recovery. It is our hope that research results presented in
these proceedings will be applied in engineering decisions, and that the workshop will act
as a catalyst in promoting the transfer of technology from theory to practice.
