Analysis reveals transient infrasound and seismic signals from surf events in Santa Barbara, suggesting connections to coastal conditions.

Transient acoustic signals can reveal sea state information, indicating significant interactions between surf and seismic activity.
Over the study period, over 10,000 independent surf repeaters were detected daily, showing high-frequency transient events of interest.
Assessment of infrasound signals showed correlation with offshore wave heights and wind speed, highlighting environmental impacts.
Localized source identification aligns with coastal features, pointing to a complex interplay between marine dynamics and acoustic responses.

Francoeur et al. (2025) studied this question.
