ESTIMATION OF SURFACE DEFORMATION DUE TO PASNI EARTHQUAKE USING SAR INTERFEROMETRY
InSAR Surface Deformation Sentinet-1 Earthquake Pasni
2018/5/11
Earthquake cause ground deformation in sedimented surface areas like Pasni and that is a hazard. Such earthquake induced ground displacements can seriously damage building structures. On 7 February 20...
THE STUDY ON THE DURABILITY OF SUBMERGED STRUCTURE DISPLACEMENT DUE TO CONCRETE FAILURE
Durability Submerged Structure Displacement Concrete Failure
2016/10/14
Concrete structures that exposed to marine environments are subjected to multiple deterioration mechanisms. An overview of the existing technology for submerged concrete, pressure resistant, concrete ...
Earth modeling and estimation of the local seismic ground motion due to site geology in complex volcanoclastic areas
dynamic amplification factor seismic tomography pyroclastic rocks finite element method
2015/9/25
Volcanic areas often show complex behaviour as far as seismic waves propagation and seismic motion at surface are concerned. In fact, the finite lateral extent of surface layers such as lava flows, bl...
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...

Non-linear effects in ground deformation at calderas due to the presence of structural discontinuities.
Drag-out effect of piezomagnetic signals due to a borehole:the Mogi source as an example
piezomagnetic effect borehole magnetic measurement the Mogi model Long Valley
2015/9/2
We show that using borehole measurements in tectonomagnetic experiments allows enhancement of the observed signals. New magnetic dipoles, which vary with stress changes from mechanical sources, are pr...

Simulation of ionospheric error on GPS signals due to changes in the direction of mobile station positions in differential GPS
Ionosphere Ray-tracing dGPS Baseline
2015/8/27
Ionospheric propagation delay is one of the major sources of error in global positioning system (GPS) precision. Therefore, accurate estimation of the ionospheric delay is required to correct GPS posi...
Ionospheric trends in Southern Hemisphere stations due to the increasing greenhouse gases concentration
Ionospheric trend EUV proxies Forecasts Dynamics
2015/8/14
The lower and middle atmosphere present long-term variations in temperature and other parameters linked to anthropogenic sources, such as the increase in greenhouse gases concentration since the start...

soil profile characteristics due varying time spans since ice retreat inner Nordfjord western Norway
2015/1/6
In the Erdalen and Bødalen drainage basins located in the inner Nordfjord in western Norway the soils were formed after deglaciation. The climate in the uppermost valley areas is sub-arctic ocean...
Indications for different types of brittle failure due to active coal mining using waveform similarities of induced seismic events
brittle failure due to active coal mining Indications
2015/1/5
Longwall mining activity in the Ruhr coal mining district leads to mining-induced seismicity. For detailed studies the seismicity of a single longwall panel beneath the town of Hamm-Herringen in the...
