Relations between pressurized triaxial cavities and moment tensor distributions

Annals of Geophysics, 2015
Pressurized cavities are commonly used to compute ground deformation in volcanic areas: the set of available solutions is limited and in some cases the moment tensors inferred from inversion of geodetic data cannot be associated with any of the available

Virial theorem for a cloud of stars obtained from the Jeans equations with second correlation moments

European Physical Journal C: Particles and Fields, 2023
A hydrodynamic model for small acoustic oscillations in a cloud of stars is built, taking into account the self-consistent gravitational field in equilibrium with a non-zero second correlation moment.

Seismological evidence for collapse of a deep geological cave—Focal mechanism of a thrust and collapse earthquake in a deep fold in the east Sichuan area

地球与行星物理论评
Do large caves exist deep underground? Through seismological investigations, we speculate the existence of a large geological cave about 7 km beneath the surface.

Relative Moment Tensor Inversion for Microseismicity: Application to Clustered Earthquakes in the Cascadia Forearc

Seismica
The relative abundance of small earthquakes affords significant opportunities for improved understanding of regional seismotectonics; however, determining moment tensors for such events recorded on regional networks is complicated by low signal-to-noise

Moment tensor solutions for the Amatrice 2016 seismic sequence

Annals of Geophysics, 2016
On August 24, 2016 a ML 6.0 earthquake struck central Italy region, nearly completely destroying some small ancient towns as Amatrice, Accumoli, Arquata and Pescara del Tronto. In the following days thousands of aftershocks have been recorded by the INGV

Sparse fault representation based on moment tensor interpolation

Seismica
Accurate representation of large earthquake sources is required for understanding rupture dynamics and improving seismic hazard assessments. While capable of capturing complex spatio-temporal slip scenarios, traditional finite-fault models often suffer ...

Ordered Rate Constitutive Theories for Non-Classical Thermofluids Based on Convected Time Derivatives of the Strain and Higher Order Rotation Rate Tensors Using Entropy Inequality

Entropy, 2020
This paper considers non-classical continuum theory for thermoviscous fluids without memory incorporating internal rotation rates resulting from the antisymmetric part of the velocity gradient tensor to derive ordered rate constitutive theories for the ...

Method for estimating the stress field from seismic moment tensor data based on the flow rule in plasticity theory

Geophysical Research Letters, 2016
The stress field is a key factor controlling earthquake occurrence and crustal evolution. In this study, we propose an approach for determining the stress field in a region using seismic moment tensors, based on the classical equation in plasticity ...
