On February 6th, 2023, Türkiye and Syria experienced the devastating effects of two large (magnitude 7.8 and 7.5) earthquakes, which triggered more than 200 aftershocks. A recent study led by first author, Gesa Maria Petersen, maps two fault zones using data produced from these earthquakes, uncovering never before mapped fault sections and ground motion along these faults.
