JUDI is a framework for large-scale seismic modeling and inversion and is designed to enable rapid translations of algorithms to fast and efficient code that scales to industry-size 3D problems. The focus of the package lies on seismic modeling as well as PDE-constrained optimization such as full-waveform inversion (FWI) and imaging (LS-RTM). Wave equations in JUDI are solved with Devito, a Python domain-specific language for automated finite-difference (FD) computations. JUDI's modeling...

CPSeis is the open-source version of ConocoPhillips' former seismic processing system. Uses Fortran 90 and C/C++ layers for I/O. The new system was designed using an MPI-parallel model and works well on Linux clusters or on individual workstations.

May 2023 The MTINV toolkit is a collection of computer code applications written to invert for the moment tensor of an earthquake given the three components of ground motion recorded at regional seismic stations (e.g., Ichinose et al., 2003). The computer codes are organized to generate moment tensor solutions for a range of source depths and origin times because of the trade-off between these two quantities. Selection criteria can be developed or a built-in default fitness functions can...

Structural Analysis Program for Civil Engineering.Can evaluate structures for static or dynamic seismic analysis. Dynamic analysis is made by accelerograms. Any analysis can be linear or non linear.

jif3d is a framework for joint inversion of different types of geophysical data in 3D. It currently comprises forward solvers for first arrival traveltimes, scalar and tensor gravity data, magnetics, electrical resistivity tomography and surface waves. An interface for magnetotelluric modelling codes is also included. The framework is flexible in terms of the coupling approach between the different datasets. At the moment cross-gradient coupling, mututal information and deterministic...

STV (a free Seismic Trace Viewer for SEGY files) is a open source pure java visualization program to quickly view SEGY format seismic data.

The shock response spectrum (SRS) allows to estimate transient acceleration signals in terms of a maximum response of a dynamic vibration system. Its origin probably dates from civil engineering and the problem of seismic excitations, i.e. earthquake response of buildings, see Clough Penzien 1975. The SRS is a spectrum, i.e. a curve giving the maximum acceleration response depending on frequency. It is derived from a 1-mass-spring-damper vibration system being excited by a base excitation, i.e...

Geophysical Library is a C++-library to handle geophysical data. At the moment the focus is on magnetotelluric and seismic data. It also includes a genetic algorithm for data inversion, signal processing and statistics routines.

JavaSeis.org: Java based software for processing and storing petroleum industry seismic data.

SeisSeek is a very lightweight utility to parse SEGY files. Users can define custom formats (byte locations). Seismic wiggle view is also available.

PRay stands for 'Plot Rayinvr' and is a graphical user interface for the ray-tracing software rayinvr (Zelt & Smith, 1992). In principle it can also be used as viewer for seismic traveltime data from other software like tomo2D. Zelt, C. A. and Smith, R. B., 1992, Seismic traveltime inversion for 2-D crustal velocity structure, Geophysical Journal International, 108(1), 16--34, 10.1111/j.1365-246X.1992.tb00836.x SYSTEM/USER REQUIREMENTS: - Linux/Mac OS X - You do need to be familiar...

Conky package to monitor the CIRES seismic alert levels for Mexico City, Oaxaca, Acapulco, Chilpancingo and Morelia.

RSTT is a software package that improves the accuracy of regional seismic travel time prediction and event location. The software package includes a computerized representation of 3-dimensional seismic wave speed for Earth's crust and shallow mantle (the outer-most 100 to 200 km of the Earth) and algorithms to calculate travel times for waves that are commonly used to locate events. RSTT was designed with real-time monitoring in mind and travel times can be computed on the fly in approximately...

Given a set of seismic arrivals for one or more events, Bayesloc estimates the joint probability of event locations, corrections to travel time predictions, precision of arrival time measurements, and phase labels for the arrival times. Bayesloc also accepts probabilistic prior constraints on any of the input parameters, which can significantly tighten the distribution of all parameters.

TotalDepth is an Open Source, cross platform, software collection that can process petrophysical data from the oil field such as wireline logs, seismic data and so on. Conventional, proprietary, software for petrophysical data tends to be expensive to licence, restrictive, slow to develop for and tied to expensive hardware. TotalDepth changes all of that. TotalDepth is open and cross-platform, and produces results straight to the bowser. TotalDepth supports such technologies such as HTML5...

A Super Mario Bros. style sidescroller game developed alongside a 2D Engine/Framework with modularity and portability in mind. Certain area's of the code are still being prototyped and developed. The code will soon be made available.

BotoSeis is a collection of interactive Java programs for seismic data processing. It may work also as a graphical user interface for packages like CWP/SU (Seismic Un*x), Madagascar and user home made programs. A new version is available at: https://github.com/botoseis/BotoSeis You can find a user guide at: https://germangarabito.wordpress.com

Main Phase Modeling, MPM, is a implementation of a 2D staggered grid solution of the elastic waveequation, using a moving zone. This enables both efficient modeling of seismic wide angle data, and modeling of selected propagating phases.
