Open-Source Seismo-Acoustic Software

The Geophysical Monitoring and Characterization Team is a diverse group of scientists addressing local and regional-scale seismological and infrasound problems through a combination of theory, data analysis and field deployments in support of United States treaty/explosion monitoring.

The team has developed several open source software projects, which can be found at the LANL-Seismoacoustics GitHub page.

InfraMonitor

InfraMonitor is a Matlab-based tool for infrasound monitoring that incorporates Los Alamos-developed detection, association, and location algorithms in addition to a Matlab implementation of the Tau-P raytracing technique (Garces et al., 1998, Drob et al., 2010).

PySAC

A Python interface to the Seismic Analysis Code (SAC) file format, supporting little and big-endian binary and alphanumeric format, containing evenly-sampled time-series data. PySAC emphasizes intuitive header access, header consistency, and ObsPy support.

GeoAc

GeoAc is a numerical package written in C++ which solves the equations governing acoustic propagation through the atmosphere in the geometric limit using a RK4 algorithm. It contains multiple instances of said equation system and is able to model propagation in an azimuthal plane using the effective motionless medium approximation as well as in three dimensions using an inhomogeneous moving background medium. The three dimensional propagation scheme include methods to model propagation in a Cartesian coordinate system as well as a spherical coordinate system which incorporates the curvature of the earth.
