Strain pattern of the Southern Tyrrhenian slab from moment tensors of deep earthquakes:implications on the down-dip velocity
southern tyrrhenian seimin strain rate tensor down-dip velocity aseismic subduction
2015/9/28
Seismic strain is analysed along the slab face of the Southern Tyrrhenian subduction zone using focal mechanisms of deep earthquakes which occurred in the period 1960-1998. Results show that the slab ...
The 2006 Kythira (Greece), Mw6.7 slab-pull event: tectonic implications and the geometry of the hellenic wadati-benioff zone
Hellenic Arc subduction zone geometry slab-pull event
2015/9/1
A strong (Mw=6.7) intermediate depth earthquake occurred on 8 January 2006 (11:34 UTC) in southwestern
Aegean Sea (Greece) causing limited damage to structures on the nearby islands of Kythira and An...
Piecewise-affine state feedback for piecewise-affine slab systems using convex optimization
Piecewise-affine systems State feedback Convex optimization Ellipsoids Lyapunov function
2015/8/10
This paper shows that Lyapunov-based state feedback controller synthesis for piecewise-affine (PWA) slab systems can be cast as an optimization problem subject to a set of linear matrix inequalities (...
Pacific plate slab pull and intraplate deformation in the early Cenozoic
Volcanic activity plate the plate and plate geometries buoyancy stokes flow solver
2015/1/6
Large tectonic plates are known to be susceptible to internal deformation, leading to a~range of phenomena including intraplate volcanism. However, the space and time dependence of intraplate deformat...
Extreme extension across Seram and Ambon, eastern Indonesia: evidence for Banda slab rollback
Seram Ambon, eastern Indonesia
2015/1/5
The island of Seram, which lies in the northern
part of the 180◦
-curved Banda Arc, has previously been interpreted as a fold-and-thrust belt formed during arc-continentcollision, which incorp...
The fate of fluids released from subducting slab in northern Cascadia
northern Cascadia subducting slab
2015/1/4
. Large amounts of water carried down in subduction zones are driven upward into the overlying forearc upper
mantle and crust as increasing temperatures and pressure dehydrate the subducting crust.

Boron and other trace element constraints on the slab-derived component in Quaternary volcanic rocks from the Southern Volcanic Zone of the Andes
Andean Arc arc lava boron prompt γ-ray analysis mantle source
2017/4/11
We present a dataset for boron and other trace element contents obtained from samples from 13 volcanoes distributed
along the Quaternary volcanic front of the Southern Volcanic Zone (SVZ) of the Chil...
The effects of the overriding plate thermal state on the slab dip in an ocean-continent subduction system
Lithosphere thermal state, numerical models, slab dip,subduction zones
2011/9/5
To evaluate the e ects of variations in the thermal state of the overriding plate on the slab dip in an ocean-continent subduction system, a 2-D nite element thermo-mechanical model was implemented. ...
Deformable two-dimensional photonic crystal slab for cavity optomechanics
two-dimensional photonic crystal slab cavity optomechanics Quantum Physics
2011/8/1
Abstract: We have designed photonic crystal suspended membranes with optimized optical and mechanical properties for cavity optomechanics. Such resonators sustain vibration modes in the megahertz rang...
Electromagnetic tunneling of obliquely-incident waves through a single-negative slab paired with a double-positive uniaxial slab
single-negative slab double-positive uniaxial slab
2011/9/2
We show that, under appropriate oblique-incidence and polarization conditions, the inherent opaqueness of a homogeneous, isotropic single-negative slab may be perfectly compensated (in the ideal lossl...
An Evaluation of Proposed Mechanisms of Slab Flattening in Central Mexico
Mexico flat slab subduction
2014/4/10
Central Mexico is the site of an enigmatic zone of flat subduction. The general geometry of the subducting slab has been known for some time and is characterized by a horizontal zone bounded on either...
We show that a metamaterial slab with arbitrary values of epsilon and mu behaves as a cloak at a finite frequency for a small object located sufficiently close to it due to the suppression of the obje...
Possible deviations from Griffith’s criterion in shallow slabs, and consequences on slab avalanche release
Griffith’s criterion shallow slabs slab avalanche release
2009/12/9
Possible reasons for deviations from Griffith’s criterion in slab avalanche triggerings are examined. In the case of a major basal crack, we show (i) that the usual form of Griffith’s criterion is val...
