Pore-pressure diffusion controls upper-plate aftershocks of the 2014 Iquique earthquake [PDF]
Nature CommunicationsUpper-plate aftershocks following megathrust earthquakes are particularly dangerous as they may occur close to densely populated regions. Aftershock numbers decay with time, imposing a time-dependent seismic hazard that is assessed with statistical ...

Omori‐like decay of postseismic velocities following continental earthquakes [PDF]
Geophysical Research Letters, 2017 Various mechanisms have been proposed to explain the transient, enhanced surface deformation rates following earthquakes. Unfortunately, these different mechanisms can produce very similar surface deformation patterns leading to difficulty in ...

Spatiotemporal functional modeling of postseismic deformations after the 2011 Tohoku-Oki earthquake [PDF]
Earth, Planets and Space, 2022 Postseismic deformations continue to occur for a long period after major earthquakes. Temporal changes in postseismic deformations can be approximated using simple functions.

A viscoelastic and afterslip postseismic deformation model for the 1964 Alaska earthquake [PDF]
Journal of Geophysical Research, 2009 We developed a 3‐D viscoelastic model, in concert with an afterslip model, to describe the postseismic deformation following the 1964 Alaska earthquake. Our model incorporates a realistic geometry including an elastic slab with very low dip angle. These geometric factors are important and require a reanalysis of the 1964 coseismic model.

Remote Sensing, 2018 The 2001 Mw7.8 Kokoxili earthquake, which occurred in the north Tibetan Plateau, ruptured ~400 km of the westernmost portion of the Kunlun fault and produced significant time-dependent postseismic deformation over a large area around the rupture zone and

On the effects of thermally weakened ductile shear zones on postseismic deformation [PDF]
Journal of Geophysical Research: Solid Earth, 2013 We present three‐dimensional (3‐D) numerical models of postseismic deformation following repeated earthquakes on a vertical strike‐slip fault. Our models use linear Maxwell, Burgers, and temperature‐dependent power law rheology for the lower crust and upper mantle.

Geophysical Research Letters, 2022 Abstract Megathrust earthquakes impose changes of differential stress and pore pressure in the lithosphere‐asthenosphere system that are transiently relaxed during the postseismic period primarily due to afterslip, viscoelastic and poroelastic processes. Especially during the early postseismic phase, however, the relative contribution

Postseismic deformation following the 2016 Kumamoto earthquake detected by ALOS-2/PALSAR-2 [PDF]
Earth, Planets and Space, 2020 I have been conducting a study of postseismic deformation following the 2016 Kumamoto earthquake using ALOS-2/PALSAR-2 acquired till 2018. I apply ionospheric correction to interferograms of ALOS-2/PALSAR-2.

Izmit earthquake postseismic deformation and dynamics of the North Anatolian Fault Zone [PDF]
Journal of Geophysical Research, 2009 We have modeled postseismic deformation from 1999 to 2003 in the region surrounding the 1999 Izmit and Düzce earthquake ruptures, using a three‐dimensional viscoelastic finite element method. Our models confirm earlier findings that surface deformation within the first few months of the Izmit earthquake is principally due to stable frictional afterslip

Earth and Space Science, 2020 Coseismic and postseismic crustal deformations caused by earthquake episodes are important in understanding the mechanisms of these episodes as well as the fault rheology near an epicentral area.
