Nonlinear Earthquake Response of Marine Sediments With Distributed Acoustic Sensing

• AutoCorrelation Functions (ACFs) of earthquakes recorded by a DAS experiment 10 exhibit phase delays with increasing ground motions 11 • ACF phase delays are converted to relative velocity drops in the medium that char-12 acterize soil nonlinearity 13 • DAS is used to infer the nonlinear behavior of soils with an unprecedented spa-14 tial resolution 15
