Distributed Acoustic Sensing (DAS) with SPECFEM

[carltape]

I'm curious whether anyone is using SPECFEM to model DAS data. A google search pointed to this study, which featured SPECFEM and SW4. Please post here if you are aware of publications or ongoing efforts. Thanks.

Here we used SPECFEM2D (postprocessed by spatial finite difference to get strain) to model a seafloor DAS section:
