Moment tensor solutions and stress regime along the Northern Caribbean plate boundary off southeastern Cuba

Seismica
For a better understanding of the kinematics and mechanics of the Oriente transform fault, a left‑lateral boundary along Cuba's southern margin in the Caribbean, we use the seismic records to determine new deviatoric moment tensor solutions by full ...

An Inversion Method Based on Inherent Similarity between Signals for Retrieving Source Mechanisms of Cracks

Aerospace, 2022
The knowledge of cracking mechanisms is significant for evaluating the healthy condition of aircraft structures and can be retrieved by moment tensor inversion based on the acoustic emission (AE) phenomenon.

General tensor decomposition, moment matrices and applications

Journal of Symbolic Computation, 2013
The tensor decomposition addressed in this paper may be seen as a generalisation of Singular Value Decomposition of matrices. We consider general multilinear and multihomogeneous tensors. We show how to reduce the problem to a truncated moment matrix problem and give a new criterion for flat extension of Quasi-Hankel matrices. We connect this criterion

Matrix moments of the diffusion tensor distribution

CoRR, 2020
Purpose: To facilitate the implementation/validation of signal representations and models using parametric matrix-variate distributions to approximate the diffusion tensor distribution (DTD) $\mathcal{P}(\mathbf{D})$. Theory: We establish practical mathematical tools, the matrix moments of the DTD, enabling to compute the mean diffusion tensor and ...

A uniform parametrization of moment tensors [PDF]

Geophysical Journal International, 2015
SUMMARY Amomenttensorisa3 ×3symmetricmatrixthatexpressesanearthquakesource.Weconstruct a parametrization of the 5-D space of all moment tensors of unit norm. The coordinates associated with the parametrization are closely related to moment tensor orientations and source types.

Seismic moment tensor and focal mechanism for earthquake of February 22, 2024 in eastern Slovakia (12:54:15 UTC, 21.75E°E, 49.03°N, depth 9 km, ML3.0)

Геофизический журнал
The accuracy of the focal mechanism solution can depend very significantly on the number of stations used, especially in the case of weak earthquakes and sparse networks.
