pyprop8: A lightweight code to simulate seismic observables in a layered half-space

Valentine, Andrew P.; Sambridge, Malcolm

Abstract

The package pyprop8 enables calculation of the response of a 1-D layered halfspace to a seismic source, and also derivatives (‘sensitivity kernels’) of the wavefield with respect to source parameters. Seismograms, seismic spectra, and measures of static displacement (e.g. GPS, InSAR and field observations) may all be simulated. The method is based on a ThompsonHaskell propagator matrix algorithm, described in O’Toole & Woodhouse (2011) and O’Toole et al. (2012). The package is entirely written in Python, dependent only on the mainstream libraries numpy (Harris et al., 2020) and scipy (Virtanen et al., 2020). As such, it is lightweight and easy to deploy across a variety of platforms, making it particularly suited to use for teaching and outreach purposes.
