The last two components correspond to CLVD
and the equivalent stresses to the crack volume [increment of V] in Eq.
Field collections and laboratory studies were supported by grants to CLVD
from the National Science Foundation (Biological Oceanography OCE-988550, OCE-9982999), NOAA's Ocean Exploration Program, the University of North Carolina-Wilmington National Undersea Research Center, and by the College of William and Mary.
If non-DC components are also considered, a volumetric and a CLVD part (in percentage of the DC component) are included.
Performing inversion we considered following source models: single DC source, single DC source with non-DC components (volumetric and CLVD), two DC sub-sources, two DC sources with non-DC components.
In addition, the ISO and CLVD
components show positive correlations that may indicate of presence of tensile faulting.
Furthermore, the deviatoric portion can be separated into a double couple and a CLVD component:
The model of the CLVD is not undisputable, since a Poisson's ratio of 0.5 would be required for its realization, even under an idealized stress regime.
In Kolar (2007a) errors of MTs were determined by mapping the parameter space around the (non-linear) solution and they were transformed into errors of source geometrical orientation (strike, dip, rake) and errors of VOL, CLVD and DC components.
Once having symbolical expression of strike, dip, rake, VOL, DC, CLVD (in a particular point--a particular solution), their partial derivatives and differential can be expressed.
The combination of isotropic and CLVD
components describes a tensile source.
Determined MTs are finally decomposed into their ISO, CLVD
and DC parts (see e.g.
[m.sub.ij] = [m.sub.ij] (ISO, CLVD
, DC, strike, dip, rake), (1)
