An Assessment of Damage to Peru’s Highway System after the M8.0 Pisco Earthquake

The performance of Peru’s highway system in this M8.0 earthquake is relevant since the infrastructure was built using the American Association off State Highway and Transportation Officials (AASHTO) specifications. The Pisco earthquake of July 2007 was a strong and unusually long-period earthquake. Soil conditions and ground water levels led to widespread liquefaction contributing to more highway damage than ground shaking did. This reconnaissance survey illustrates why geotechnical considerations are paramount. Because some bridges were subject to secondary hazards such as rockfall, there is also a case for consideration of multiple hazards during the design or retrofit of bridges.
