EERI's Learning From Earthquakes (LFE) Program invites you to a FREE webinar series this month with the LFE and GEER reconnaissance teams that traveled to Turkey in March to assess the impacts of the February 6, 2023 Kahramanmaraş Earthquake Sequence.
LFE Kahramanmaraş Earthquakes Buildings Reconnaissance Webinar
Tuesday, May 23, 2023
10:00 AM-11:30 AM Pacific Time

The EERI Buildings Team traveled more than 3200 kilometers through the earthquake-affected region of Turkey in mid-March 2023, conducting reconnaissance in İskenderun, Samandağı, Kırıkhan, Antakya, Adana, Osmaniye, Kahramanmaraş, Gaziantep, Adıyaman, Gölbaşı, Malatya, Hassa, İslahiye and Nurdağı. The team focused on understanding the overall structural performance of buildings, including correlation with peak ground intensity at nearby ground motion recording stations. The majority of the buildings were residential, but the team also documented and categorized the response of industrial facilities, commercial buildings, school buildings, and religious and historical structures. The building sample includes reinforced concrete, steel moment frame, precast concrete, and unreinforced masonry buildings. The team also recorded damage to nonstructural building components. In this webinar, members of the team will present their findings and respond to questions.
Moderator: Eduardo Miranda, Stanford University
Speakers:
- Parth Gudhka, IMEG
- Bora Genturk, University of Southern California
- Halil Sezen, Ohio State University (team lead)
- Rupa Garai, SOM
- Morgan Griffith, Exponent
- Michael Mieler, ARUP
An additional webinars will take place in the following week at the same time on Tuesday. The May 30th webinar will focus on geotechnical impacts, with members of the GEER reconnaissance teams.
Registering once at the above link will allow you to attend any of the webinars in the series. PDHs for each webinar will be available at no charge to EERI members, and at a fee of $35 per webinar for non-members.

In this webinar, members of the lifelines reconnaissance team will share their findings on the structural and nonstructural performance of the infrastructures that facilitate the functioning of society. Lifelines include bridges, roads, tunnels, railroads, metro and tram stations, airports, ports, dams, electrical transmission lines, substations, gas transmission lines, water pipes, chemical plants, and power plants. The team gathered data on more than 150 sites throughout the affected region, looking at performance and functionality, the types of failures that caused disruptions, damage patterns, and properties of lifelines that ensured good performance during the earthquakes.
On February 6, 2023, a M7.8 earthquake occurred in southern Turkey near the northern border of Syria, followed about 9 hours later by a M7.5 earthquake approximately 90 km to the north of the first. The impacts of these earthquakes were devastating. The number of fatalities in both countries has risen to more than 50,000. According to Turkish government sources, more than 200,000 buildings collapsed or suffered damage severe enough to require demolition. Over a million people have been displaced as a result.
