self-potential signals multifractal formalism
2015/9/14
Multifractal analysis was performed to characterize the fluctuations in dynamics of the hourly time variability of self-potential signals measured from January 2001 to September 2002 by three stations...
Ambient vibration measurements in the Southern Rhine Graben close to Basle
H/V ratio ambient vibration array analysis fundamental frequency Rhine Rift Valley
2015/9/11
This study presents results of ambient noise measurements from temporary single station and small-scale array deployments in the northeast of Basle. H/V spectral ratios were determined along various p...

UV-VIS instruments remote-sensing actinic measurements satellite data validation
2015/9/7
The present paper describes a UV-VIS spectroradiometer named GASCOD/A4r developed at ISAC-CNR for remote sensing measurements aboard stratospheric M55-Geophysica aircraft, flying up to 21 km. Obtained...
A network of tiltmeters has been operational on Vulcano Island for numerous years. At present, the network comprises five functioning borehole stations, four of which are installed at 8-10 m and allow...
Continuous SO2 flux measurements for Vulcano Island,Italy
SO2 Differential optical absorption spectroscopy Vulcano Island Network for Observation of Volcanic and Atmospheric Change
2015/8/24
The La Fossa cone of Vulcano Island (Aeolian Archipelago, Italy) is a closed conduit volcano. Today, Vulcano Island is characterized by sulfataric activity, with a large fumarolic field that is mainly...
Assessing accuracy of gas-driven permeability measurements: a comparative study of diverse Hassler-cell and probe permeameter devices
gas-driven permeability measurements diverse Hassler-cell probe permeameter devices

Permeability is one of the most important petrophysical parameters to describe the reservoir properties of sedimentary rocks, pertaining to problems in hydrology, geothermics, and hydrocarbon reservoi...
BrO/SO2 molar ratios from scanning DOAS measurements in the NOVAC network
BrO/SO2 molar ratios scanning DOAS measurements NOVAC network
2015/1/6
The molar ratio of BrO to SO2 is, like other halogen/sulfur ratios, a possible precursor for dynamic changes in the shallow part of a volcanic system. While the predictive significance of the BrO/SO2 ...
Measurements of the Magnetism of the Mars-96 Small Station at the Nurmijärvi Geophysical Observatory
