The Asymmetric Seismic Moment Tensor in Micropolar Media

open access: yesBulletin of the Seismological Society of America, 2018
Coseismic block rotations are observed in the vicinity of seismogenic faults and have an effect on the moment tensor. This can be accounted for using the linear micropolar theory, which allows the existence of an independent rotation or spin θ different from the continuum rotation 1=2 curl u.

Seismic Source Radiation and Moment Tensor in the Time Domain

1997
Seismic waves in an elastic medium are produced by an inelastic deformation at the seismic source. Let us assume that the seismic source occupies the volume V, in which the body forces f are present, and in which the jump of displacement takes place on the surface Σ, composed of a positive side, Σ+, and a negative side, Σ−, with the unit vector, v ...

Decomposition of seismic moment tensors for underground nuclear explosions

pure and applied geophysics, 1996
Generally the decomposition of a seismic moment tensor is not unique. However, to favorably view the characteristics of a certain seismic source, one must decompose a seismic moment tensor into parts according to assumptions about the properties of the seismic source.

Defining the scalar moment of a seismic source with a general moment tensor

Bulletin of the Seismological Society of America, 1999
Abstract We compare several published definitions of the scalar moment M0, a measure of the size of a seismic disturbance derived from the second-order seismic moment tensor M (with eigenvalues m1 ≥ m3 ≥ m2). While arbitrary, a useful definition is in terms of a total moment, MT0 = MI + MD, where MI = |M|, with M = (m1 + m2 + m3)/3, is ...

Moment Tensor Analysis of Rockslide Seismic Signals

Bulletin of the Seismological Society of America, 2015
Abstract Seismic signal analysis can provide valuable information to understand rockslide dynamics in the absence of direct observation. Established methods of moment tensor inversion may assist with rapid rockslide parameter estimation, which can be crucial for mitigating secondary hazards.
