The m-Morisita index analysis was applied to the Swiss seismicity to investigate its space clustering properties. The analysis of the whole and aftershock depleted catalogs has revealed that the whole catalog is more spatially clusterized than the depleted one and that the clustering increases...

The sequence of magnitudes of the earthquakes occurred in Kachchh area (Gujarat, Western India) from 2003 to 2012, has been analysed by using the multifractal detrended fluctuation analysis. The complete and the aftershock-depleted catalogues with minimum magnitude M3 were investigated. Both...

The time dynamics of gravity signal measured in Sheki, a site in Azerbaijan, where mainly crust deformation processes are present, is investigated by using the power spectrum method and the multifractal detrended fluctuation analysis. Our findings point out to the presence of two main...

The time dynamics of seismic microtremors recorded in several sites in Chisinau City (Moldova) are analysed by means of the informational approaches of the Fisher Information Measure (FIM) and the Shannon entropy. The sites show different soil characteristics. One of the investigated sites,...

A Langevin-type equation for stochastic processes with a periodical correlation function is introduced. A procedure of reconstruction of the equation from time series is proposed and verified on simulated data. The method is applied to geophysical time series–hourly time series of wind speed...

The time dynamics of seismograms of nine tectonic earthquakes which occurred in Vrancea (Romania) registered at three seismic stations located in Moldova are analyzed by means of the informational approach of the Fisher Information Measure (FIM). The three seismic stations in Moldova are...

Scaling behaviors in monthly streamflow and Standardized Streamflow Index (SSI) of 11 gauging stations in Ebro basin (Spain) were analyzed: four located in the mainstream and seven in tributaries. The time span is from 1950 to 2005. The methods used are the power spectrum and the detrended...

The correlation structures in 15 Bach’s sinfonias were analyzed. Each sinfonia is characterized by the superposition of three voices. Each voice is a sequence of pitches. Each voice was transformed in a time series, in which the sampling time was given by the smallest pitch duration in that...

We investigated the dynamics of particulate matter data, recorded in Tito, a small industrial area of southern Italy. The analysis of these signals was performed using the Fisher information measure (FIM), which is a powerful tool for investigating complex and nonstationary signals, and the...

The scaling behaviour of the 1981–2007 seismicity data in central Italy, which is one of the most seismically active areas in Italy is investigated. In particular we examined the earthquakes located in a circular area centred on the epicentre of the strongest event, occurred in September 26,...
