The mechanics of Campi Flegrei unrests as related to plastic behaviour of the caldera borders
Campi Flegrei unrest machanism caldera structure discontinuities plastic effects
2015/10/8
We present here a model which explains the mechanism of generation of unrest episodes at Campi Flegrei caldera from a mechanical point of view. The mechanism involves the effects of plastic zones at t...
Local time behaviour of low frequency geomagnetic field fluctuation power at low latitude
Geomagnetic pulsation MHD waves and instabilities
2015/9/28
In this paper we present a statistical study of the local time behaviour of low frequency (0.7-4.0 mHz) geomagnetic field fluctuation power at a low latitude station (corrected geomagnetic latitude 36...
This paper deals with some fundamental considerations regarding the behaviour of geotechnical structures under seismic loading. First a complete definition of the earthquake disaster risk is provided,...
The 3550 year BP-1944 A.D.magma-plumbing system of Somma-Vesuvius: constraints on its behaviour and present state through a review of Sr-Nd isotope data
Somma-Vesuvius magma chamber crustal contamination
2015/9/15
Vesuvius, dominating the densely-populated Neapolitan area, is one of the most dangerous volcanoes in the World. Its destructive power derives from energetic subplinian and plinian eruptions, such as ...
The oscillatory behaviour of the aftershocks rate of the 2001 Bhuj earthquake, India: observation and interpretation
aftershocks Bhuj earthquake Omori'sLaw GBA array Lg magnitude
2015/9/14
A damaging earthquake of Mw 7.7, which struck the Bhuj region of India on January 26, 2001, was followed by a large number of aftershocks. The aftershock data available at Gauribidanur Seismic Array S...
Experimental study on the behaviour of nonductile infilled RC frames strengthened with external mesh reinforcement and plaster composite
Experimental study behaviour nonductile infilled RC frames strengthened external mesh reinforcement plaster composite

The aim of this paper is to report on an experimental study about Turkish Earthquake Code on suggested strengthening method. The proposed method uses existing brick infill walls and the strengthening ...
Analysis of the atmosphere behaviour in the proximities of an orographic obstacle
atmosphere behaviour proximities of an orographic obstacle
2009/11/16
The atmospheric behaviour near an orographic obstacle has been thoroughly studied in the last decades. The first papers in this field were mainly theoretical, being more recent the laboratory experime...
On the origin of time-dependent behaviour in a barotropically unstable shear layer
time-dependent behaviour unstable shear layer
2009/11/12
An experimental study on the instability of a detached Stewartson layer, using an annular, rotating tank with flat, rigid upper and lower boundaries, showed an instability to steady vortices at a crit...
Fractal behaviour of the seismicity in the Southern Iberian Peninsula
Fractal behaviour of the seismicity Southern Iberian Peninsula
2009/11/9
The fractal behaviour of the seismicity in the Southern Iberian Peninsula is analysed by considering two different series of data: the distance and the elapsed time between consecutive seismic events ...
