Seismic Waves and Analysis

Abstract On 10 August 2025 (19:53 local time), a Mw 6.1 earthquake with a shallow focal depth of 10.72 km struck the Sındırgı district within Türkiye’s Western Anatolia extensional province, resulting in one fatality, multiple injuries, and notable structural damage. Although the event ruptured the Sındırgı segment of…

Seasonal modulation of seismicity has been reported in several regions worldwide, suggesting that earthquake occurrence may be sensitive to small, time-dependent stress perturbations. Such observations point to a range of hydro-meteorological processes that can generate seasonal stress changes, including variations in…

Automated Machine Learning (AutoML) frameworks are efficient tools for predictive model applications. Several machine learning algorithms can integrate them. This study presents a comprehensive evaluation of four AutoML frameworks that are FLAML, H2O, TPOT, and PyCaret to predict the fundamental frequency of perforate…

Abstract This study presents an integrated geophysical investigation of the Zeyve Höyük archaeological site, combining magnetic data analysis and electrical resistivity tomography (ERT) to delineate buried structural features. Magnetic anomalies were processed using a discrete wavelet transform (DWT) with the Haar mot…

Recent earthquakes in Türkiye, including the 2020 Samos and 2023 Kahramanmaraş events, have once again underscored the significant impact of local ground conditions and the three-dimensional structure of alluvial basins on earthquake ground motion. In such settings, seismic wave propagation is strongly controlled by b…

Abstract This study characterizes the dynamic properties of soils in the seismically active Sakarya Region, located within the complex tectonic structures of the North Anatolian Fault Zone, using ambient seismic noise data collected from 63 stations. Parameters such as Vs 30 , peak ground acceleration (PGA), horizonta…

Phase picking in seismology is the first step of signal processing and locating a seismic event. At the beginning of seismological research, it is straightforward to manually pick P- and S-wave arrival times because the number of seismic stations is relatively small. Recently, instrumentation has improved, and the gap…

Aktif fay hatları ve yoğun nüfusu nedeniyle Ege Bölgesi yüksek deprem riski taşımaktadır. Bu riskin doğru şekilde değerlendirilmesinde, yerel zemin koşullarını yansıtan yüksek frekanslı spektral sönümleme katsayısının ("kappa", ) bilinmesi kritik öneme sahiptir. Bu çalışmada, AFAD tarafından işletilen Türkiye Ulusal…
