After six years of quietness La Fournaise volcano entered into activity on March 9, 1998. Fissures opened gradually downwards on the northern flank of the cone. Two cones, Kapor and Krafft built, from...
Tomographic analysis of self-potential data in a seismic area of Southern Italy

The Normalized Wavelet Cross-Correlation Function (NWCCF) was used to study correlations between the series of extreme events in self-potential data and earthquakes, both modelled as stochastic point ...
Wavelet analysis as a tool to characteriseand remove environmental noisefrom self-potential time series
self-potential signals wavelet analysis
2015/9/14
Multiresolution wavelet analysis of self-potential signals and rainfall levels is performed for extracting fluctuations in electrical signals, which might be addressed to meteorological variability. I...
