The method was evaluated using synthetic tests covering both intra-network and extra-network scenarios and applied to 121 shallow events in the eastern Black Sea region. Unlike traditional approaches that minimize travel-time residuals via partial derivatives, this framework maps Pg arrival-time uncertainties into a bounded three-dimensional compatibility space defined over the discretized hypocentral search grid.

Understanding seismic wave attenuation in such a tectonically complex region is critical, as it provides insights into crustal heterogeneities, fluid distribution, and fault zone properties, which are essential for unravelling the seismic hazard potential and tectonic evolution of the region. This study presents a 3D coda wave attenuation (Qc⁻¹) model of the central KRB at central frequencies of 1.5 and 3 Hz, derived from 3,404 local earthquake events using a sensitivity kernel approach based on Paasschen’s equation within the framework of radiative transfer theory. Checkerboard tests were conducted to evaluate model stability and resolution and it is observed that optimal results were found in 10–40 km depths. The model reveals moderate to high attenuation anomalies in the upper 15 km, attributed to thick sedimentary deposits and upper crustal heterogeneity. A highly attenuated zone at 20–30 km depth in the eastern region suggests fluid-filled fractures or intrinsic attenuation within fault zones. A narrow moderate attenuation zone at 35–40 km depth in the central part of the study region may indicate a deep fluid reservoir. The Kachchh Mainland Fault (KMF) zone exhibits high attenuation down to 15 km, while the South Wagad Fault (SWF) zone shows moderate to high attenuation extending to 40 km, suggesting SWF serves as a primary conduit for fluid migration from the reservoir to epicentral depths.

Reported magnitudes were homogenized to moment magnitude (M_w) using General Orthogonal Regression (GOR), and dependent events were removed to isolate background seismicity.

As one of the most devastating events in the region’s history, the earthquake inflicted widespread destruction across Myanmar and neighboring countries. In the absence of a comprehensive strong motion instrumentation specifically along the Sagaing fault (seismic zone V), physics-based simulations offer an essential window into understanding the spatial variability of ground motions and their implications for seismic hazard assessment. In the present study, broadband ground motions are simulated over a near-field domain spanning approximately a 3° × 5° region around the multi-segmented fault plane of the event. To generate these ground motion time histories, the deterministic low-frequency waveforms are combined with stochastic high-frequency components, informed by regional crustal velocity models, topography and detailed source rupture parameters. The reliability of the simulated ground motions is assessed through comparisons with the limited available recordings in the near-field region, with residual analysis quantifying the level of agreement. Furthermore, the ground motions are synthesized on a dense grid of 0.1° × 0.1° and visualized through contour maps of peak ground acceleration (PGA). The highest PGA values are found to be 0.71 g, 0.86 g, and 0.40 g in the EW, NS, and vertical components, respectively. Additionally, the spatial distribution of the peak ground residual displacements is illustrated along with the stations proximal to the fault plane. Finally, the simulated PGAs are compared against global empirical ground motion models developed for subduction zones to evaluate their consistency and regional applicability. Thus, the study demonstrates the importance of simulation-based approaches for seismic hazard evaluation in data-scarce regions, thus offering valuable input for guiding future seismic instrumentation strategies and improving hazard awareness along the Sagaing Fault.</p></div>","PeriodicalId":16994,"journal":{"name":"Journal of Seismology","volume":"30 3","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147829184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
