Plenary Session: Reconnaissance, Response, and Recovery: Lessons Learned from the 2023 Kahramanmaraş Earthquake Sequence
Tuesday, April 9, 2024, 4:00 PM–5:30 PM
Metropolitan Ballroom
This plenary session opens the 2023 Kahramanmaraş Earthquakes Anniversary Program Track at 2024AM, organized in partnership with the National Earthquake Hazards Reduction Program (NEHRP). The M7.8 and M7.5 earthquakes that struck southern Turkey on February 6, 2023 affected a wide region of southern Turkey and northern Syria, killing nearly 60,000 people and damaging or destroying hundreds of thousands of buildings in more than 10 major cities. In this plenary, speakers from Turkey and the United States will present a multidisciplinary overview of the response to these earthquakes, the ongoing recovery process, and the lessons learned for earthquake risk and resilience in the region and beyond. Speakers will address topics including the coordination of the international earthquake reconnaissance response, the structural engineering impacts and what they mean for building codes and retrofit standards, and the social and economic impacts of the earthquakes as they relate to business resilience and gender, and the temporary rehousing and long-term rebuilding process.
