    Formal Quantification of Spatially Differential Characteristics of PSI-Derived Vertical Surface Deformation Using Regular Triangle Network: A Case Study of Shixi in the Northwest X... by Cunfa Zhao, Langping Li, Huiyong Yin, Guanhua Zhao, Wei Wang, Jianxue Huang, Qi Fan

    Published 2025-04-01
    “…Applied to the Shixi area in China’s Northwest Xuzhou Coalfield, the RTN-based framework revealed that (1) the SDVSD directionality aligned with the coal strata dip and working face distribution, contrasting with VSD’s focus on the magnitude and rate alone; (2) SDVSD exhibited seasonal rate fluctuations suggesting environmental influences, and, unlike VSD, it has a non-additivity property in temporal evolution; (3) there was spatial divergence between SDVSD and VSD, i.e., high VSD rates did not necessarily correlate with high SDVSD rates, emphasizing the need for an independent spatial gradient analysis. …”

    Reflection seismic imaging across the Thinia valley (Greece) by S. Zappalá, A. Malehmir, H. Kranis, G. Apostolopoulos, M. Papadopoulou

    Published 2025-05-01
    “…Results show a low-velocity zone with no reflectivity from the surface to approximately 100 m depth probably related to the presence of loose material, under which two main east-dipping reflections are imaged. Considering the surface geology and tectonic history of the valley, we interpret these reflections as the same lithological boundary displaced by three highly east-dipping thrust/reverse faults probably part of the Hellenide thrusts. …”
