Geodetic deformations in the Central-Southern Apennines (Italy) from repeated GPS surveys
Geodesy GPS central-southern apennines strain rate seismotectonic
2015/9/28
We computed the horizontal strain rate field for a sector of tbc Central-Southern Apennines (Italy) from GPS data collected during yearly repeated campaigns performed from 1994 to 2000 on tbc GeoModAp...
Geodetic deformation Across the Central Apennines from GPS Data in the time span 1999-2003
Geodetic Deformation Gps Apennines
2015/9/10
Abstract During the time span 1999-2003 was set up and repeatedly surveyed a not permanent GPS network located across one of the highest seismic areas of the central Apennines (Italy). The Central Ape...
Kinematics and strain analyses of the eastern segment of the Pernicana Fault (Mt.Etna,Italy) derived from geodetic techniques (1997-2005)
GPS EDM ground deformation Pernicana Fault Mt. Etna
2015/9/8
This paper analyses the ground deformations occurring on the eastern part of the Pernicana Fault from 1997 to 2005. This segment of the fault was monitored with three local networks based on GPS and E...
Inversion of synthetic geodetic data for the 1997 Colfiorito events:clues on the effects of layering,assessment of model parameter PDFs,and model selection criteria
data inversion geodesy coseismic displacement
2015/9/1
The 1997 September-October Umbria-Marche sequence has been extensively studied in the past by analyzing coseismic displacement data (GPS, leveling, SAR). Here we focus on synthetic data representative...
Improved geodetic European very-long-baseline interferometry solution using models of antenna gravitational deformation
very long baseline interferometry antenna deformation signal path variation crustal deformation height bias
2015/8/28
Very-long-baseline interferometry (VLBI) is used for establishing global geodetic networks where the coordinates attain a 1-mm level of precision. Technique-dependent bias can degrade the VLBI positio...
The expanding Earth at present:evidence from temporal gravity field and space-geodetic data
station coordinates and vertical velocities temporal gravity variation principal inertia moments Earth expansion
2015/8/27
The Earth expansion problem has attracted great interest, and the present study demonstrates that the Earth has been expanding, at least over the recent several decades. Space-geodetic data recorded a...
Analysis of the displacement of geodetic stations during the Emilia seismic sequence of May 2012
Crustal deformations GPS Geodesy InSAR Coseismic deformation
2015/8/26
The two events of Mw 6.11 and 5.96 [EMERGEO Working Group 2012, this volume] that took place on May 20 and 29, 2012, respectively, in the Po Plain, and the associated seismic sequence, represent the r...
Combination of coseismic displacement fields: a geodetic perspective
Crustal deformation Data processing GPS coseismic displacement, combination
2015/8/26
This study provides the mathematical framework for the rigorous combination of coseismic offsets observed by a global positioning system (GPS) network and investigates the results obtained on the occa...
Using the Nordic Geodetic Observing System for land uplift studies
Geodetic observation systems observation system the earth observatory database data set
2015/1/6
Geodetic observing systems have been planned and developed during the last decade. An ideal observing system consists of a network of geodetic observing stations with several techniques at the same si...
Rupture Kinematics of the 2005Mw8.6 Nias–Simeulue Earthquake from the Joint Inversion of Seismic and Geodetic Data
Rupture Kinematics 2005Mw8.6 Nias–Simeulue Earthquake the Joint Inversion of Seismic Geodetic Data
2014/4/15
The 2005Mw8.6 Nias–Simeulue earthquake was caused by rupture of a portion of the Sunda megathrust offshore northern Sumatra. This event occurred within an array of continuous Global Positioning System...
Towards inferring earthquake patterns from geodetic observations of interseismic coupling
earthquake patterns geodetic observations interseismic coupling
2014/4/8
Ultimately, seismotectonic studies seek to provide ways of assessing the timing, magnitude and spatial extent of future earthquakes. Ample observations document the spatial variability in interseismic...
