Camurcu, Melike; Oral, Vildan; Cengiz, Ekrem
Following the 2023 Kahramanmaraş-centered earthquakes in Türkiye, multi-actor and multi-sectoral response structures were implemented, creating significant challenges in coordination. Accordingly, the current study aims to assess the factors affecting intra- and inter-team coordination in disaster response processes, as well as the factors that negatively impact coordination activities, and to propose recommendations for improvement. The study is based on data collection from expert participants working at the disaster coordination center using qualitative research methods. Thematic analysis was used in the analysis of interview data, and coordination problems were identified as arising from seven main themes. The results highlight the importance of reducing centralization, modular training, empowering local actors, horizontal organization, delegation of authority, and participatory governance models.

Ozturk, Serkan; Alkan, Hamdi
In this study, current earthquake hazard is tried to present and earthquake forecasting is made for Lake Van and its adjacent area for the next five years. For this purpose, a statistical analysis is achieved with the concomitant use of the b-value, Z-value, relative intensity (RI) and pattern informatics (PI) data. In addition, for the earthquake forecasting in the intermediate term and hazard, a comprehensive discussion is made with the studies analyzing the different seismological and geophysical variables in literature. The relations between these parameters reveal more accurate and reliable approaches. Consequently, at the beginning of 2022, particularly the areas having small b-value and large Z-value with the hotspots (possible earthquake areas) between 2022 and 2027 from the combined forecast map are determined in and around Muradiye, Çaldıran, Özalp, Van city centre and Gevaş including Çaldıran, Yeniköşk, Erciş and Malazgirt faults with Saray and Van Fault zones.

Öztürk, Serkan
The purpose of this study is to make detailed statistical analyses of earthquake occurrences in and around the Central Anatolian Region of Turkey and to forecast the possible earthquake regions in the future. In this scope, by performing the region-time-magnitude analyses of seismotectonic variables such as Mc-value, b-value, Dc-value, Z-value, the current/future earthquake potential was defined. b-value was computed as 1.26±0.07 by taking Mc=2.6 and this large value indicates that the earthquakes with small magnitude are dominant. Dc-value was calculated as 1.31±0.03 and this relatively small value shows that distance between the epicenters approaches the diameter of cluster, and earthquake activity is more clustered in larger regions/at smaller scales. Anomaly regions with low b-value and large Z-value at the beginning of 2019 were found in and around Tuz Gölü Fault Zone, Central Anatolian Fault Zone, Salanda and Niğde faults. As an important result, these regions may be considered as the most likely regions for strong/large earthquakes in the future.
