Influence of lithospheric and mantle stratification on global post‐seismic deformation [PDF]

Geophysical Research Letters, 1997
A new class of multilayered, viscoelastic Earth models based on PREM, with an incompressible, linear, viscoelastic Maxwell rheology, is applied to the modeling of co‐seismic and post‐seismic deformation following large earthquakes. The novelty of our approach stands on the usage, for the first time in post‐seismic studies, of a fully analytical scheme ...

Mechanics of near-field deformation during co- and post-seismic shallow fault slip [PDF]

Scientific Reports, 2020
AbstractPoor knowledge of how faults slip and distribute deformation in the shallow crust hinders efforts to mitigate hazards where faults increasingly intersect with the expanding global population at Earth’s surface. Here we analyze two study sites along the 2014M6.0 South Napa, California, earthquake rupture, each dominated by either co- or post ...

Pseudotachylyte-Mylonites Record of Transient Creep From Inter-Seismic Ductile to Co-Seismic Rupture

Frontiers in Earth Science, 2022
Transient creep during an earthquake cycle is very important to understand the rheology of fault and deformation mechanisms in the brittle–plastic transition zone.

Transient deformations in the Suez-Sinai area from GPS observations [PDF]

, 2005
We analyze data from four GPS campaigns carried out between 1997 and 2002 on a network of 11 sites in the Suez-Sinai, the area of collision between the African and the Arabian plates.

Asperities and barriers on the seismogenic zone in North Chile: state-of-the-art after the 2007 Mw 7.7 Tocopilla earthquake inferred by GPS and InSAR data [PDF]

, 2010
The Mw 7.7 2007 November 14 earthquake had an epicentre located close to the city of Tocopilla, at the southern end of a known seismic gap in North Chile. Through modelling of Global Positioning System (GPS) and radar interferometry (InSAR) data, we show

GPS source solution of the 2004 Parkfield earthquake [PDF]

, 2014
We compute a series of finite-source parameter inversions of the fault rupture of the 2004 Parkfield earthquake based on 1 Hz GPS records only. We confirm that some of the co-seismic slip at shallow depth (

Effects of Earth's gravitation and compressibility on co- and post-seismic deformations

Geophysical Journal International, 2022
SUMMARY In this paper, we systematically analyse the effect of Earth's gravitation and compressibility on co- and post-seismic deformations. Based on the analytical solution of dislocation Love number (DLN) in a non-gravitational and incompressible homogeneous Earth model, it was seen that reducing the density of the homogeneous Earth ...

Post-seismic relaxation from geodetic and seismic data

Geodesy and Geodynamics, 2017
We have examined the aftershock sequence and the post-seismic deformation process of the Parkfield earthquake (2004, M = 6, California, USA) source area using GPS data.

Post-injection normal closure of fractures as a mechanism for induced seismicity [PDF]

, 2017
Understanding the controlling mechanisms underlying injection-induced seismicity is important for optimizing reservoir productivity and addressing seismicity-related concerns related to hydraulic stimulation in Enhanced Geothermal Systems.
