Mapping and interpretation of satellite magnetic anomalies from POGO data over the Antarctic region
Antarctic geomagnetic field magnetic field satellites magnetic anomalies
2015/10/8
A satellite magnetic anomaly map made using the POGO magnetic field data is compared to three maps made using Magsat data. A total of 14 anomalies with magnitudes greater than 3 nT can be identified i...
Analysis of the seismicity of Southeastern Sicily: a proposed tectonic interpretation
Historical seismicity Macroseismics source parameters quaternary tectonics seismogenic faults hyblean plateau SE Sicily
2015/9/30
Southeastern Sicily is one of the Italian regions with high seismic risk and is characterised by the occurrence in the past of large destructive events (MS = 6.4-7.3) over a territory which is densely...
Three-dimensional interpretation of MT data in volcanic environments (computer simulation)
3D interpretation magnetotelluric data imaging monitorinc volcanoes magma chamber remote sounding
2015/9/28
The research is aimed, first, to find components of MT-fields and their transforms, which facilitate the imaging of the internal structure of volcanoes and, second, to study the detectability of condu...
Interpretation of magnetic anomalies using the horizontal gradient analytic signal
horizontal gradient analytie signal horizontal derivative vertical derivative interpretation aeromagnetic anomaly magnetic anomaly
2015/9/28
In recent years the analytic signal method has been of great utility in the interpretation of potential field data. The amplitude of the 3D analytic signal of magnetic data yields information on the l...
Improved techniques in data analysis and interpretation of potential fields:examples of application in volcanic and seismically active areas
gravimetry potential fields geomagnetism signal enhancement techniques
2015/9/25
Geopotential data may be interpreted by many different techniques, depending on the nature of the mathematical equations correlating specific unknown ground parameters to the measured data set. The in...
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...
Preseismic ULF effectand possible interpretation
Ultra-Low Frequency emission seismicity Alfven waves
2015/9/14
We present the results of ULF magnetic field observation at Karimshino station (Kamchatka, Russia). Using a case study we discovered an effect of suppression of ULF intensity about 2-6 days before rat...
Anomaly crust fields from MAGSAT satellite measurements:their processing and interpretation
MAGSAT satellite data magnetic andgravity anomalies wavelet and maximum entropyanalysis earthquake hypocenters
2015/9/14
The space distribution of the magnetic anomaly field for the Pacific Ocean is obtained from data of the satellite MAGSAT. A number of long-wavelength magnetic anomalies of the region are identified. A...

Nubia-Eurasia kinematics: an alternative interpretation from Mediterranean and North Atlantic evidence
Nubia-Eurasia kinematics Mediterranean region Plio-Quaternary deformation
2015/9/2
It is argued that the Plio-Quaternary deformation pattern in the Mediterranean region is compatible with a SSWNNE
convergence between Africa (Nubia) and Eurasia and that the significant difference be...
Global nonlinear optimization for the estimation of static shift and interpretation of 1-D magnetotelluric sounding data
Magnetotelluric sounding global nonlinear optimization static shift TE and TM mode apparent resistivity phase
2015/8/27
In the presence of conducting inhomogeneities in near-surface structures, apparent resistivity data in magnetotelluric sounding can be severely distorted. This is due to electric fields generated from...
Constraining fault interpretation through tomographic velocity gradients: application to northern Cascadia
Constraining fault interpretation velocity gradients
2015/1/4
Spatial gradients of tomographic velocities are
seldom used in interpretation of subsurface fault structures.
This study shows that spatial velocity gradients can be used
effectively in identifying...
