文摘
- •
The Shapiro–Francia (S–F) test statistic is used to identify seismic events and construct optimal filtering trajectories.
- •
We propose an optimal spatiotemporal time–frequency peak filtering method to attenuate random noise and preserve seismic signals simultaneously.
- •
The OST–TFPF reduces bias of seismic signal estimate by reinforcing morphology characteristics of seismic events using S-F.
