dMODELS is a MATLAB software package designed to study ground deformation near active volcanoes and faults using data from GNSS, InSAR, and tiltmeters data. The software includes tools for data preparation, modeling the source of deformation, and creating professional figures. It works on Windows, MacOS, and Linux computers and comes with instructions and examples.

dMODELS uses simplified models that represent underground sources as pressurized cavities or flat surfaces in an idealized Earth. These idealized sources aren’t real physical objects but help approximate how the crust is being deformed. They can estimate the location, depth, and volume change of the deformation source, but can’t reveal the actual size or composition of a magma reservoir.

Even though these models rely on several simplifications, they can provide valuable insights into volcanic and fault activity when applied carefully to high-quality data.
