A probabilistic earthquake source inversion framework. Designed and crafted in Mordor.
Grond is an open source software tool for robust characterization of earthquake sources. Moment tensors and finite fault rupture models can be estimated from a combination of seismic waveforms, waveform attributes and geodetic observations like InSAR and GNSS. It helps you to investigate diverse magmatic, tectonic, and other geophysical processes at all scales.
It delivers meaningful model uncertainties through a Bayesian bootstrap-based probabilistic joint inversion scheme. The optimisation explores the full model space and maps model parameter trade-offs with a flexible design of objective functions.
Rapid forward modelling is enabled by using pre-computed Green’s function databases, handled through the Pyrocko software library. They serve synthetic near-field surface displacements and synthetic seismic waveforms for arbitrary earthquake source models and geometries.
Installation with pip
See also: Grond Manual: Installation
Grond and all its dependencies can be installed by running
pip install grond # read below...
but, we recommend to make a conscious decision about how its main dependency Pyrocko and especially Pyrocko’s own dependencies are installed. The Pyrocko Installation Manual describes different installation schemes.
As a general advice, we recommend to exclusively use either, (1) the system’s native package manager, (2) Anaconda, or (3) pip only. In (1) and (2), only resort to use pip for those few packages which are not available as native packages. Otherwise, competing package managers will ruin your day!
To prevent pip from automatically resolving dependencies run
pip install --no-deps grond
Documentation and examples can be found in the Grond Manual.
