Improving resolution model of probable asperity distribution along southern Sumatra Subduction Zone using denser GPS stations

Geomatica
The southern Sumatra Subduction Zone (SSZ) is point outed as an area with seismic potential due to plate tectonic movement. To observe seismic activity in this region, Global Positioning System (GPS) networks can be used to monitor tectonic plate ...

A physics-based approach of deep interseismic creep for viscoelastic strike-slip earthquake cycle models

, 2019
International audienceSUMMARY Most geodetic inversions of surface deformation rates consider the depth distribution of interseismic fault slip-rate to be time invariant. However, some numerical simulations show downdip penetration of dynamic rupture into

Interseismic coupling and refined earthquake potential on the Hayward‐Calaveras fault zone [PDF]

, 2015
Interseismic strain accumulation and fault creep is usually estimated from GPS and alignment arrays data, which provide precise but spatially sparse measurements.

Interseismic Coupling Along the Java‐Timor Subduction‐Collision Zone at East Indonesia

Geophysical Research Letters
The Java‐Timor subduction‐collision zone is one of the most tectonically complicated structures along the strike of the Indonesia‐Australia convergence. This complexity makes it difficult to interpret observations of interseismic deformation.

Goce derived geoid changes before the Pisagua 2014 earthquake

Geodesy and Geodynamics, 2018
The analysis of space – time surface deformation during earthquakes reveals the variable state of stress that occurs at deep crustal levels, and this information can be used to better understand the seismic cycle.

Creep on the Argentine Precordillera Décollement Following the 2015 Illapel, Chile, Earthquake: Implications for Andean Seismotectonics

Geophysical Research Letters
The Central and South‐Central Andes form a “two‐sided” mountain belt bounded by distinct zones of convergence in the forearc and backarc flanks. Previous geodetic interseismic deformation studies found that the forearc to backarc velocity field is better

Inference of Multiple Earthquake-Cycle Relaxation Timescales from Irregular Geodetic Sampling of Interseismic Deformation [PDF]

, 2014
Characterizing surface deformation throughout a full earthquake cycle is a challenge due to the lack of high‐resolution geodetic observations of duration comparable to that of characteristic earthquake recurrence intervals (250–10,000 years).

Large-Scale Interseismic Crustal Deformation, Fault Slip Rate, Coupling and Earthquake Potential in the Upper Yellow River Basin

Remote Sensing
The Upper Yellow River Basin (UYRB) is one of the most tectonically complex and seismically active regions in China, but the detailed crustal deformation and interseismic fault couplings, providing the essential parameters for geodynamics and seismic ...

Decomposing DInSAR Time-Series into 3-D in Combination with GPS in the Case of Low Strain Rates: An Application to the Hyblean Plateau, Sicily, Italy

Remote Sensing, 2017
Differential Interferometric SAR (DInSAR) time-series techniques can be used to derive surface displacement rates with accuracies of 1 mm/year, by measuring the one-dimensional distance change between a satellite and the surface over time.

Active deformation near the Nicoya Peninsula, northwestern Costa Rica, between 1996 and 2010: Interseismic megathrust coupling [PDF]

, 2012
We use campaign and continuous GPS measurements at 49 sites between 1996 and 2010 to describe the long-term active deformation in and near the Nicoya Peninsula, northwestern Costa Rica.
