    A monitored building with a cracked lower joint and a slower vibration trace, suggesting a loss of stiffness.

    When frequency changes signal structural damage

    14 minute read      STRUCTURAL-HEALTH-MONITORING     

    An unexpected drop in a building’s natural frequency is the structure reporting that it has lost stiffness — usually the first sign of damage. Here is why to...

    Seismic waveform ribbons converge into a shared learned representation and branch into several task-specific outputs.

    From phase pickers to seismic foundation models

    11 minute read      DEEP-LEARNING     

    Foundation models ask whether one pretrained representation of seismic waveforms can support picking, detection, classification, and other downstream tasks—w...

    A winding trail of sample points crosses a foggy probability landscape and gathers densely around its high ground.

    Markov chain monte carlo for geoscientists

    An intuitive guide to MCMC: a walker in the fog whose footprints map the posterior. We build a Metropolis sampler from scratch, check it against an exact ana...

    An irregular earthquake-location probability cloud within a cutaway Earth volume and adaptive search grid.

    Probabilistic earthquake location with nonlinloc

    How NonLinLoc locates earthquakes by mapping a full probability density over the search volume instead of iterating to a single point — the Bayesian idea, th...
