These problems are:

* ``CMTProblem``

* :ref:`cmt`

A problem that solves for a centroid moment tensor point source (derived from Pyrocko's ``CMTSource``). This problem fits the very general earthquake source analysis based on far-field seismic waveforms.

* ``DoubleDCProblem``

* :ref:`double_dc`

A problem that solves for two double-couple point sources (derived from ``DoubleDCSource``). This problem can be used to solve for somewhat complex, *segmented earthquake sources* to better fit far-field seismic data.

* ``RectangularProblem``

* :ref:`rectangular`

A problem that solves for a rectangular finite source (derived from Pyrocko's ``RectangularSource``). This problem fits well to large earthquakes and/or problems for which near-field surface displacement data (InSAR, GNSS, etc.) are available.

* :ref:`volume_point`

A problem that solves for a spherical volume point (infinite) to model magmatic or volcanic processes. Only static targets (GNSS or InSAR) are supported.

To define and configure a problem the part called ``problem_config`` in the configuration is set up.
