Full-waveform inversion (FWI) has emerged as a transformative method in seismic imaging, employing the entire recorded seismogram to iteratively reconstruct detailed subsurface models.

There are two novel aspects to her team’s approach, she says. The first is to analyse five different aspects of the seismic waveform to pick out from the noise exactly when an event occurred.

These findings underscore the potential of using high-quality seismic waveform data and flexible analytical methods to robustly and rapidly estimate complex source processes immediately after an ...

In such cases, a Doppler-like directivity effect usually results in sharp, high-amplitude pulse waveforms recorded in the rupture propagation direction (south of the epicenter in this instance).
