“…These results are consistent with those of Zhou et al. (2021), except a large discrepancy for EGF2. These relocations have no impact on the foregoing AMRF analysis, given the alignment adjustments made to the deconvolved signals.…”

“…With the hypocenter located at ∼10 km (8 km from the YEA catalog; 10 km from the CENC catalog with limited solution; 6.69 km from the high‐resolution catalog by Zhou et al. (2021), and 11 km relocated using handpicked P arrivals by Chen et al., 2022), the main slip during the M W 6.0 Yangbi mainshock is likely to be at depths around 6–12 km and any shallow slip is minor.…”

“…Such strategy gives reliable and highly complete detection, and thus, the catalog reaches a complete magnitude of M L 1.0 and a minimum magnitude of M L ‐1.0. The relocation process utilized cross‐correlated differential travel times, which provides sub‐sampling‐rate precision (<0.01‐s), leading to a relative location uncertainty of ∼10 m laterally and ∼20 m vertically in the hypoDD inversion process (Waldhauser, 2001; Zhou, Ghosh, et al., 2021). Note that the real location uncertainty is larger than that given by least‐square criteria.…”

“…Different from the methods above that use only manually designed features for quality control, deep-learning-based methods can automatically extract abundant features from labeled receiver functions. Deep learning has made significant progress not only in the field of artificial intelligence over the last decade (LeCun et al, 2015), such as natural language processing and computer vision, but also in a variety of seismic applications (e.g., Kong et al, 2018;Zhou et al, 2021). In brief, deep learning aims to automatically build a mapping function from input to output with a given dataset.…”
