February 27, 2010 Chile Earthquake


On February 27, 2010 there was a magnitude 8.8 earthquake in Chile. The region of the most intense shaking was the Concepcion-Valparaiso area however strong shaking was felt throughout Chile and Argentina and shaking was also felt in parts of Bolivia, southern Brazil, Paraguay, Peru and Uruguay. It is estimated that at least 8 million people were affected by the earthquake and it resulted in approximately 452 casualties, left approximately 800,000 people homeless, and caused approximately $30 billion dollars in damage. An earthquake-generated tsunami was measured around the Pacific Ocean and caused localized regions of damage, especially in Chile.

Many research teams have visited the region to conduct post-earthquake reconnaissance. PEER sponsored the travel of three researchers who joined the EERI Reconnaissance team to investigate the damage:

  • – Jack Moehle, UC Berkeley Professor, former PEER director and EERI Chile Reconnaissance team leader
  • – Mark Yashinsky, Senior Bridge Engineer at Caltrans
  • – Scott Ashford, Oregon State Professor and Department Head for the School of Civil and Construction Engineering

Upon the return of both the EERI and GEER Reconnaissance Teams from Chile, PEER co-hosted the first reconnaissance briefing that was webcast live from UC Berkeley. The presentations and videos from this briefing are posted on this website as well as photos from Professor Jack Moehle. Reports from these researchers and reconnaissance teams will be posted on the website as they become available.
