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.
GEER Kahramanmaraş Earthquakes Reconnaissance Webinar: Geotechnical Impacts
Tuesday, May 30, 2023

On May 30, in the final webinar in this series, the Geotechnical Extreme Events Reconnaissance (GEER) Association will share reconnaissance findings on the geotechnical impacts of the February 6, 2023 earthquake sequence. GEER and EERI sent an advance reconnaissance team to Turkey in mid-February, a week after the earthquakes, to collect perishable data and identify areas for further research. A Phase I GEER team followed to collect data along extensive fault ruptures, inspect affected dams, and map areas with variable levels of liquefaction-related damage. A Phase II GEER team later performed reconnaissance of liquefaction-related damage to port facilities and foundations. Members of all teams will join the webinar to present on their findings and respond to questions from the audience.

LFE Kahramanmaraş Earthquakes Buildings Reconnaissance Webinar
Tuesday, May 16, 2023
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.
