Presented here is select observations of the seismic performance of earth dams and port facilities from the 2023 Turkiye Earthquakes. The 2023 Februrary 6th events included a M7.8 and M7.7 within 9 hours of each other on separate but adjacent faults. Ground shaking was recorded throughout the region with median values at roughly one half gravity. Seventeen earth dams experienced some type of geotechnical damage due to liquefaction, fault rupture, or seismic compression. Several ports facilities were also impacted by liquefaction and/or lateral spreading. A synopsis of key geotechnical earthquake damage patterns is presented.
