Forecasting strong aftershocks in earthquake clusters from northeastern Italy and western Slovenia

, 2020
In this study, we propose an analysis of the earthquake clusters that occurred in North-Eastern Italy and western Slovenia from 1977 to today. Given a mainshock generating alarm in the population, we are interested in forecasting if a similar magnitude ...

On the evolution of elastic properties during laboratory stick-slip experiments spanning the transition from slow slip to dynamic rupture [PDF]

, 2016
The physical mechanisms governing slow earthquakes remain unknown, as does the relationship between slow and regular earthquakes. To investigate the mechanism(s) of slow earthquakes and related quasi-dynamic modes of fault slip we performed laboratory ...

基于压缩感知理论的远震P波数据重建研究

Dizhen xuebao
本文将基于压缩感知理论的地震观测数据重建方法用于天然远震事件的P波到时处理之中，基于曲波（curvelet）变换，建立基于L1范数的正则化反演模型，并采用迭代收缩阈值算法（ISTA）求解该模型。针对在内蒙古布设的流动地震台阵记录到的远震波形数据，对其进行稀疏采样，采用稀疏反演重建方法对欠采样数据进行重建，并拾取重建数据的P波到时，之后开展远震P波层析成像进行验证。研究结果表明，远震天然地震观测数据在曲波变换中表现出稀疏性，可利用压缩感知方法实现远震P波数据的完备化处理 ...

基于四川地震预警站网数据的震相检测模型迁移学习研究

Dizhen xuebao
2023年中国建成了全球规模最大的地震预警网，预警网中的台站配置了速度计、加速度计、简易烈度计（MEMS）等多种地震仪器。目前用于深度学习模型训练的数据集主要由速度计数据组成，不同类型仪器记录的数据在处理时精度会下降。为了解决这一问题，本文使用Yu等（2023）发布的BRNN模型作为预训练模型；然后使用2万6 739条人工标注的四川地区的速度计、加速度计和MEMS数据进行迁移学习。实验结果表明：迁移学习显著提升了模型对加速度计和MEMS预警仪器数据记录到的Pg，Sg震相的检测精度 ...
