Monitoring motions and the surface deformations

The transformation of displacement vectors due to the surface movements into the parameters of deformation is one of the possible tools for better expressions of dynamical properties for recent movement studies. The procedure for data processing is 2-dimensional in regular rectangular grids.

After processing results of observations, the movements are expressed by means of they vectors, related to the coordinate system. Those properties affect the interpretation of movements, and, moreover, may not be understandable for specialists in other geosciences. It is the reason why vectors of movements are also transformed in parameters of deformations, then comparable with results of earthquake focal mechanism analysis. These parameters are important for modeling of geodynamical phenomena.
