Detecting time series anomalies using hybrid methods applied to Radon signals recorded in caves for possible correlation with earthquakes

Popis výsledku v původním jazyce

Anomalies in the Radon activity concentration time series recorded in five European caves (Czech Republic, Slovakia, Slovenia) are detected using three hybrid methods: (1) multiple linear regression and autoregressive integrated moving average statistical methods, (2) Empirical Mode Decomposition with Support Vector Regression techniques and (3) the Singular Spectrum Analysis composed with a predicting methodology. Results coming from the three methods are compared and the best hybrid method is selected based on statistical evaluation criteria of the uncertainty. Radon anomalies occur +/- 30 days from earthquake occurrence, selected according to the Dobrovolsky's earthquake preparation zone formula and to seismic events (with magnitude >= 4) occurred in the neighboring European Countries to the monitoring caves. The anomalies detection furnishes results consistent across the used methodologies, as proven by the calculation of a statistical parameter that search the presence of anomalies coming from the hybrid methods within +/- 30 days from earthquake event.
