EERI-GEER Advance Team Reconnaissance Briefing Webinar Recording
A joint EERI-GEER advance reconnaissance team conducted field visits in the disaster zone in southern Turkey from February 15-20. The team traveled over 1,500 km in the regions affected, first along a north-to-south path, and then east-to-west in the southern third of the region. They collected perishable geotechnical data, made observations of structural damage, and […]
