Application of the relocation-error distribution on geomagnetic databases. Analyses on the «Historical Italian Geomagnetic Data Catalogue
geomagnetism magnetic dating relocation
2015/9/1
The reliability of the Historical Italian Geomagnetic Data Catalogue, comprising 536 directions and 393 intensities, has been assessed by comparing the historical geomagnetic measurements with the GUF...
Can WAAS Availability Be Inferred From Geomagnetic Data? An Analysis

The Federal Aviation Administration’s Wide Area Augmentation System (WAAS) provides high integrity GPS-based precision navigation service to users in the conterminous United States (CONUS). User integ...
Fractal analysis of the ULF geomagnetic data obtained at Izu Peninsula,Japan in relation to the nearby earthquake swarm of June–August 2000
Fractal analysis ULF geomagnetic data Izu Peninsula nearby earthquake swarm
2009/12/11
In our recent papers we applied fractal methods to extract the earthquake precursory signatures from scaling characteristics of the ULF geomagnetic data, obtained in a seismic active region of Guam Is...
Multifractal analysis for the ULF geomagnetic data during the 1993 Guam earthquake
Multifractal analysis ULF geomagnetic data Guam earthquake
2009/11/9
In our previous papers we have shown that the fractal (monofractal) dimension (Do) showed a significant increase before the Guam earthquake occurred on 8 August, 1993. In order to have a further suppo...
An attempt to find precursors in the ULF geomagnetic data by means of flicker noise spectroscopy
ULF geomagnetic data means of flicker noise spectroscopy
2009/11/9
The flicker noise spectroscopy which is a new phenomenological method for the retrieval of information contained in chaotic time signals, is based on the analysis of recognizable irregularities (pulse...
A case for variational geomagnetic data assimilation:insights from a one-dimensional,nonlinear,and sparsely observed MHD system
geomagnetic data assimilation one-dimensional nonlinear observed MHD system
2009/11/2
Secular variations of the geomagnetic field have been measured with a continuously improving accuracy during the last few hundred years, culminating nowadays with satellite data. It is however well kn...
Principal component analysis and singular spectrum analysis of ULF geomagnetic data associated with earthquakes
Principal component analysis singular spectrum analysis ULF geomagnetic data
2009/12/29
In order to extract any ULF signature associated with earthquakes, the principal component analysis (PCA) and singular spectral analysis (SSA) have been performed to investigate the possibility of dis...
