| Zusammenfassung |
| Multifractal fluctuations in the time dynamics of geoelectrical data,
recorded in a seismic area of southern Italy, have been revealed using the
Multifractal Detrended Fluctuation Analysis (MF-DFA), which allows to detect
multifractality in nonstationary signals. Our findings show that the
geoelectrical time series, recorded in the seismic area of southern Apennine
Chain (Italy), is multifractal. The time evolution of the multifractality
suggests that the multifractal degree increases prior the occurrence of
earthquakes. This study aims to propose another approach to investigate the
complex dynamics of earthquake-related geoelectrical signals. |
