2018/5/15
On August 8, 2017, an earthquake of M 7.0 occurred at Jiuzhaigou. Based on the Sentinel-1 satellite InSAR data, we obtained coseismic deformation field and inverted the source slip model. Result...
FEMSA: a finite element simulation tool for quasi-static seismic deformation modeling

2015/9/2
We set up a computational tool to numerically model static and quasi-static deformation generated by faulting
sources embedded in plane or spherical domains. We use a Finite Element (FE) approach to ...
Global nonlinear optimization for the estimation of static shift and interpretation of 1-D magnetotelluric sounding data
Magnetotelluric sounding global nonlinear optimization static shift TE and TM mode apparent resistivity phase

2015/8/27
In the presence of conducting inhomogeneities in near-surface structures, apparent resistivity data in magnetotelluric sounding can be severely distorted. This is due to electric fields generated from...
Static stress transfer from the May 20,2012,M 6.1 Emilia-Romagna (northern Italy) earthquake using a co-seismic slip distribution model

2015/8/26
We model the static stress transfer for the May 2012 northern Italy earthquakes, assuming that failure of the crust occurs by shear. This allows the mechanics of the process to be approximated by the ...
The MgSiO3 system at high pressure: Thermodynamic properties of perovskite, postperovskite, and melt from global inversion of shock and static compression data

2014/4/8
We present new equation-of-state (EoS) data acquired by shock loading to pressures
up to 245 GPa on both low-density samples (MgSiO3
glass) and high-density,
The quasi-static approximation of the spring-slider motion

2009/11/16
The spring-slider is a simple dynamical system consisting in a massive block sliding with friction and pulled through a spring at a given velocity. Understanding the block motion is fundamental for st...
Faults self-organized by repeated earthquakes in a quasi-static antiplane crack model
Faults self-organized by repeated earthquakes quasi-static antiplane crack model
font style='font-size:12px;'>
2009/11/13
We study a 2D quasi-static discrete crack anti-plane model of a tectonic plate with long range elastic forces and quenched disorder. The plate is driven at its border and the load is transferred to al...

2009/11/11
Temporal and spatial characteristics of intense quasi-static electric fields and associated electric potential structures in the return current region are discussed using Cluster observations at geoce...
