The principal axes of stress and strain are inferred for the seismotectonic zones of the Friuli–
Venezia Giulia region, which forms the eastern part of the European Southern Alps. This …

The study of crustal deformation using various types of geodetic data is a research topic
whose practical importance needs hardly to be stressed, and its theoretical richness …

Geoscientists have undertaken mapping of the Earth's crustal strain (or stress) fields using a
great variety of field data. The output can be represented by a 3-D second-rank symmetric …

In the deformation analysis in geosciences (geodesy, geophysics and geology), we are
often confronted with the problem of a two-dimensional (or planar and horizontal), symmetric …

By applying integrated least-squares adjustment of multicampaigns geographic positioning
system (GPS) measurements, the velocity of any GPS monument can be obtained. The …

We investigate the time–distance dependence of the 3‐D rotation angle, Φ, for pairs of focal
mechanisms in the worldwide Harvard catalogue. We study the original catalogue as well as …

This investigation implements a least-squares methodology to fit a triaxial ellipsoid to a set of
three-dimensional Cartesian coordinates obtained from present-day geospatial techniques …

Let there be given a twodimensional symmetric rank two tensor of random type (examples:
strain, stress) which is either directly observed or indirectly estimated from observations by …

The eigenspace components (ie principal components and principal directions) play a key
role in the validation of a symmetric rank-two random tensor, eg for strain and stress. They …

The random principal eigenvalues and random eigenvector parameters have been routinely
estimated from second-rank symmetric (SRS) random tensors and geophysically interpreted …
