SeisMIC - an Open Source Python Toolset to Compute Velocity Changes from Ambient Seismic Noise

Blog Article

We present SeisMIC, a fast, versatile, and adaptable open-source software to estimate seismic velocity changes from arrethe bush balm ambient seismic noise.SeisMIC includes a broad set of tools and functions to facilitate end-to-end processing of ambient noise data, from data retrieval and raw data analysis via spectrogram computation, over waveform coherence analysis, to post-processing of the final velocity change estimates.A particular highlight of the software is its ability to invert velocity change time series onto a spatial grid, making it possible to create maps of velocity changes.To tackle the challenge of processing large continuous datasets, SeisMIC can exploit multithreading at high efficiency with an about five-time 15-eg2373cl improvement in compute time compared to MSNoise, probably the most widespread ambient noise software.In this manuscript, we provide a short tutorial and tips for users on how to employ SeisMIC most effectively.

Extensive and up-to-date documentation is available online.Its broad functionality combined with easy adaptability and high efficiency make SeisMIC a well-suited tool for studies across all scales.
