🚨 New Research Highlight
I am excited to share our latest work, “Remotely sensing stress evolution in solids: a passive approach to earthquake monitoring,” now available on arXiv:2509.00268.
In this study, we introduce a stress-sensitive transformation of seismic noise that reveals systematic pre-earthquake signatures not captured by existing methods. If validated across broader datasets and settings, this approach could represent a game-changing advance in earthquake physics and geophysics, opening a new pathway for passively tracking stress evolution in the Earth’s crust.
I encourage researchers in seismology, geophysics, acoustics, and related fields to read, test, challenge, and build upon this work.
Tracking Cascadia slow-slip events with the Shakibay-Senobari stress-sensitive frequency-domain transform.
The top panel shows GPS motion and seismic tremor during episodic tremor and slip (ETS) events beneath southern Vancouver Island (2010–2013), highlighting the timing of slow-slip initiation and termination.
The lower panels show the Shakibay-Senobari stress-sensitive frequency-domain transform (SS_f) computed from continuous seismic noise. Between ETS events, SS_f evolves smoothly as stress accumulates along the fault, followed by a rapid drop and recovery during slow slip. This behavior captures the full loading–release–relaxation cycle and complements GPS and tremor observations.
