The Mid-America Earthquake (MAE) Center reconnaissance report on the Maule (Chile) earthquake of February 27, 2010 is now available from http://mae.cee.uiuc.edu/publications/2010/10-04.htm. The report includes observations of the MAE Center team on the damaged ports, buildings, bridges, and historical structures. A detailed chapter on engineering seismology develops spectrum compatible ground motions for various sites in Chile that are proposed for use in risk assessment studies. Two bridges and a building structure that exemplified the most commonly observed failures are selected, advanced numerical models are built, and inelastic dynamic analyses are conducted to provide further insight to the field observations. The report also features a dedicated chapter on transportation networks, roads and embankments where the performance is assessed using field data. Another chapter focuses on the role of media after the earthquake and provides useful insight on the response of the affected population to communicate in the aftermath of a disaster.
