Pattern of seismic deformation in the Western Mediterranean
Deformation seismicity geodynamics Mediterranean
2015/10/8
The seismic deformation of the Western Mediterranean was studied with the aim of defining the strain pattern that characterizes the Africa-Eurasia plate boundary in this area. Within different section...
Late Cenozoic deformation of the Gavrovo and Ionian zones in NW Peloponnesos (Western Greece)

2015/9/29
The structural deformation of Mesozoic-Tertiary sediments of the Ionian and Gavrovo zones in NW Peloponnesos is related to the propagation of a fold-thrust system during the Cenozoic. The sediments of...

A Margulis spacetime is a complete affine 3-manifold
M with nonsolvable fundamental group. Associated to every Margulis spacetime is a noncompact complete hyperbolic surface S.
We show that eve...

Numerous newly-identified traces of active faults in the Himalayan foothill zone along the HFF around Chandigarh, in Pinjore Dun, along the piedmont zone of the Lower Siwalik hill front and within the...
Finite element analysis of ground deformation due to dike intrusion with applications to Mt. Etna volcano
FEM ground deformation dike intrusion real medium
2015/9/15
A 2D finite elements study was carried out to analyse the effects caused by dike intrusion inside a heterogeneous medium and with a realistic topography of Mt. Etna volcano. Firstly, the method (dimen...
Local stresses, dyke arrest and surface deformation in volcanic edificesand rift zones
dyke injection dyke arrest crustalstresses crustal layering surface deformation volcanic hazard
2015/9/15
Field studies indicate that nearly all eruptions in volcanic edifices and rift zones are supplied with magma through
fractures (dykes) that are opened by magmatic overpressure. While (inferred) dyke ...
