Ates, Erdem
On February 6, 2023, two earthquakes occurred in Kahramanmaraş province, which are among the largest earthquakes in the history of Türkiye. The purpose of the study is to determine how these earthquakes affected the exports and imports of the region. In the study, export and import data of Türkiye and 11 provinces declared as earthquake zones were used monthly for the period from January 2021 to December 2023. In the study, the foreign trade data of the region were first examined descriptively and then with the Bai and Perron test to determine whether the earthquake caused a structural break. As a result, it was determined that the earthquakes caused a structural break in both exports and imports. After the earthquakes, exports quickly returned to their pre-earthquake levels, but a similar recovery was not observed in imports.

This article presents the results of the first paleoseismological studies conducted along the Ulubat Fault and their inferences on the earthquake behavior of the south branch of the North Anatolian Fault Zone (NAFZ). The Ulubat Fault is divided into 3 segments according to its geometric characteristics and paleoseismological behavior. Along the fault segments, at least 6 paleoearthquake event have been distinguished in the last 16 thousand years with paleoseismolgic fault excavations. The dating results correlated with the historical records show that the latest surface ruptures along the Ulubat Fault occurred with the earthquakes of <161/170 AD (I=IX), 1143 AD (M=6.0) and 1855 AD (M=7.3), respectively, and migrated to the west. Although it does not provide sufficient statistical evaluation opportunity, the paleoseismological data presented in this study proves that the segments of the NAFZ south branch do not present characteristic earthquake behavior in terms of recurrence period and this irregularity may be due to the multi-fragment geometry of the fault zone in the region.

Sancak-Uzunpazar Fault Zone is N40E-trending sinistral shear zone that has a 50 km length and 5 km width between Karakocan (Elazığ) in southwest and Kaynarpınar (Bingöl) in northeast. The fault extends parallelly to East Anatolian Fault is bounded by the North Anatolian Fault to the northeast and Karakoçan Fault to the southeast. Herein, morphological features, the tectonic setting of the Sancak-Uzunpazar Fault Zone and the first paleoseismological studies on it is represented. The Sancak-Uzunpazar Fault Zone is consist of two parallel segments (called East and West) with a 1.5 km distance. Conducted field studies and aerial photogrometry show that the segments exhibit morphological features like faceted surfaces, faulted scarps, shutter ridges, and offset streams. Especially, average offsets are about 7-12 m along the eastern segment while the cumulative maximum offset reaches 1.1 km. Moreover, revealed paleoseismological data show evidence of at least two surface ruptures during Holocene. Obtained morphological data reveal that the Sancak-Uzunpazar Fault Zone may have a relatively lower slip rate when compared to other active faults in the region and the reflection of the slip rate to the morphology is more evident in the eastern segment.
