摘要: We observed a remarkable near-to-unity correlation between the time series of Acoustic Emissions (AEs) collected at two stations approximately 300 km apart from each other and located along Apennine belt (Italy). This finding prompted us to verify hypothesis that AE signals can carry with them an indication anomalies in crustal stress trend, possibly related earthquake occurrences. Thus, we checked ability Recurrence Quantification Analysis Fractal as applied identify signal phase transitions before crisis occurs. The sharp drop Percent Determinism after its maximum value, simultaneously minimum values Dimension (D), few days some seismic events take place, seems point relevance proposed approach precursor detection.
