Two‐stage composite megathrust rupture of the 2015 Mw8.4 Illapel, Chile, earthquake identified by spectral‐element inversion of teleseismic waves

Geophysical Research Letters, 2016
The Mw8.4 Illapel earthquake occurred on 16 September was the largest global event in 2015. This earthquake was not unexpected because the hypocenter was located in a seismic gap of the Peru‐Chile subduction zone. However, the source model derived from 3‐

Analogue earthquakes and seismic cycles: experimental modelling across timescales [PDF]

Solid Earth, 2017
Earth deformation is a multi-scale process ranging from seconds (seismic deformation) to millions of years (tectonic deformation). Bridging short- and long-term deformation and developing seismotectonic models has been a challenge in experimental ...

Statistical physics of earthquakes: Comparison of distribution exponents for source area and potential energy and the dynamic emergence of log-periodic energy quanta [PDF]

, 2000
We investigate the relationship between the size distribution of earthquake rupture area and the underlying elastic potential energy distribution in a cellular automaton model for earthquake dynamics.

Role of fault branches in earthquake rupture dynamics [PDF]

Journal of Geophysical Research: Solid Earth, 2007
We analyze earthquake ruptures propagating along a straight “main” fault and encountering a finite‐length branch fault. Such intersections are often observed in natural fault systems. The predicted effects of the interaction with the branch that we report can be remarkable; they can strongly perturb the propagation velocity on the main fault and, in ...

On the contribution of the horizontal sea-bed displacements into the tsunami generation process [PDF]

, 2012
The main reason for the generation of tsunamis is the deformation of the bottom of the ocean caused by an underwater earthquake. Usually, only the vertical bottom motion is taken into account while the horizontal co-seismic displacements are neglected in

Deformation due to the 17 August 1999 Izmit, Turkey, earthquake measured from SPOT images [PDF]

, 2002
The geometry of the ruptured areas and the coseismic slip distribution data are key to highlighting the behavior of seismic faults. This information is generally retrieved from field investigations and geodetic measurements or synthetic aperture radar ...

Dynamic earthquake rupture preserved in a creeping serpentinite shear zone [PDF]

Nature Communications, 2018
AbstractLaboratory experiments on serpentinite suggest that extreme dynamic weakening at earthquake slip rates is accompanied by amorphisation, dehydration and possible melting. However, hypotheses arising from experiments remain untested in nature, because earthquake ruptures have not previously been recognised in serpentinite shear zones.

Earthquake Stress Drops From Dynamic Rupture Simulations Constrained by Observed Ground Motions

Geophysical Research Letters, 2020
Stress drop characterizing dynamics of earthquake rupture propagation has various definitions and measures with a yet unclear mutual relationship. We aim to reconcile this discrepancy by analyzing synthetic dynamic rupture models generated by random ...

Earthquake-induced fracture displacements and transmissivity changes in a 3D fracture network of crystalline rock for spent nuclear fuel disposal

Journal of Rock Mechanics and Geotechnical Engineering, 2023
During the long service period of a nuclear waste repository in crystalline rock, large earthquake(s) may occur nearby the repository site and coseismically alter the local stress field around pre-existing fractures within the geological formation.

Tsunami generation by dynamic displacement of sea bed due to dip-slip faulting [PDF]

, 2008
In classical tsunami-generation techniques, one neglects the dynamic sea bed displacement resulting from fracturing of a seismic fault. The present study takes into account these dynamic effects.
