The mineralogy, petrography, and oxygen-isotope compositions of porphyritic chondrules—dominant chondrule type
in most chondrite groups—suggest formation by incomplete melting of isotopically diverse...
Stress tensor inversion in Western Greece using earthquake focal mechanisms from the Kozani-Grevena 1995 seismic sequence
stress distributions inversion fault plane solutions Greece
font style='font-size:12px;'>
2015/10/8
Stress tensor inversion has been applied to estimate principal stress axes orientations in Western Greece, from 178 earthquake fault plane solutions from the Kozani-Grevena May 13, 1995 sequence. All ...

2015/9/11
We present here the second release of a database, running on MS-Access platform, of the earthquake focal mechanisms of the Mediterranean area, published in the literature. For all of the mechanisms (m...
Inferences on the source mechanisms of the 1930 Irpinia (Southern Italy) earthquake from simulations of the kinematic rupture process
1930 Irpinia earthquake ground motion simulation kinematic source model
font style='font-size:12px;'>
2015/9/11
We examine here a number of parameters that define the source of the earthquake that occurred on 23rd July 1930 in Southern Italy (in the Irpinia region). Starting from the source models proposed in d...
Mechanisms of geometrical seismic attenuation
Seismic attenuation

2015/8/27
In several recent reports, we have explained the frequency dependence of the apparent seismic quality-factor (Q) observed in many studies according to the effects of geometrical attenuation, which was...
Chaotic behavior of seismic mechanisms: experiment and observation
Earthquake modeling chaos theory
font style='font-size:12px;'>
2015/8/24
To simulate the dynamics of earthquakes, a mechanical prototype was constructed that was inspired by the Burridge-Knopoff model and equipped with accurate instrumental devices. The data obtained by th...
Buried active faults in the Zafferana Etnea territory (south-eastern flank of Mt. Etna): geometry and kinematics by earthquake relocation and focal mechanisms
Seismic swarm Waveform correlation Precise relocation Fault plane geometry
font style='font-size:12px;'>
2015/8/18
We relocated seismicity that occurred from 2000 to 2005 inside a sector of Mt. Etna, comprising the town of Zafferana Etnea, using the double-difference technique. This approach revealed some spatial ...
Focal mechanisms in the southern Aegean from temporary seismic networks – implications for the regional stress field and ongoing deformation processes
Focal mechanisms the southern Aegean temporary seismic networks the regional stress field ongoing deformation processes
font style='font-size:12px;'>
2015/1/6
The lateral variation of the stress field in the southern Aegean plate and the subducting Hellenic slab is determined from recordings of seismicity obtained with the CYCNET and EGELADOS networks in th...
Exhumation of (ultra-)high-pressure terranes: concepts and mechanisms
Ultra-high pressure crustal rocks in phanerozoic continental plate subduction collision events
font style='font-size:12px;'>
2015/1/5
The formation and exhumation of high and ultra-high-pressure, (U)HP, rocks of crustal origin appears to be ubiquitous during Phanerozoic plate subduction and continental collision events. Exhumation o...
An Evaluation of Proposed Mechanisms of Slab Flattening in Central Mexico
Mexico flat slab subduction
font style='font-size:12px;'>
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...
Baroclinic instability of a symmetric,rotating,stratified flow:a study of the nonlinear stabilisation mechanisms in the presence of viscosity
Baroclinic instability nonlinear stabilisation mechanisms presence of viscosity
