A denoising method for concrete cracking electromagnetic signals based on grey wolf optimized VMD-WT
Published 2025-02-01“…Simulation and experimental results demonstrate that, in comparison to traditional denoising methods for electromagnetic signals, the proposed approach yields a higher signal-to-noise ratio, lower mean squared error, and greater waveform similarity. This method exhibits stronger adaptability for denoising non-stationary electromagnetic signals generated during concrete cracking.…”

Narrow intermediate-depth seismogenic band related to flexural strain in relatively dry Peruvian flat slab
Published 2025-02-01“…Abstract The distribution and rupture properties of intermediate-depth earthquakes (70–300 km) provide insights into the interior stress state of the subducting plate, its petrological composition, and the subduction history. Here we evaluate the kinematic spatio-temporal rupture evolutions of four M7+ intermediate-depth earthquakes beneath Peru between 1997 and 2021 using teleseismic waveforms, which reveal similar rupture behavior over a limited depth range within the flat-slab segment. …”
