English(EN) Evaluating PhaseNet on Teleseismic Data with MsPASS

PhaseNet 工作流提高地震波探测精度

研究人员开发了一种使用 PhaseNet 机器学习模型的新工作流,以提高远震数据的地震波探测能力。该工作流在 MsPASS 中实现,与在区域数据上训练的模型相比,P波拾取的召回率显著提高了 700% 以上。虽然增加模型大小提高了准确性,但推理速度却急剧下降,这表明与 CPU 相比,GPU 更适合扩展此应用程序。 AI

影响 提高了地震数据分析的准确性,可能有助于地震探测和研究。

    在远震数据上使用 MsPASS 评估 PhaseNet

    arXiv:2605.22837v1 Announce Type: cross Abstract: Numerous studies have shown that the machine-learning picker PhaseNet produces accurate P and S picks on local earthquake signals, but its performance can degrade sharply on teleseismic signals. To address this limitation, we pres…
