As such, they present a unique example for a complex time series. We apply the recently introduced method of natural time analysis, which enables the detection of long-range temporal correlations even in the presence of heavy tails and find that the acoustic emissions exhibits features similar to that of other equilibrium or non-equilibrium critical systems such as worldwide seismicity as presented in the Centennial earthquake catalogue which includes global seismicity events with magnitude . These results support the universal behaviour of the fracturing processes from the laboratory to the global scale. date: 2013-10-15 date_type: published publisher: ELSEVIER official_url: https://doi.org/10.1016/j.physa.2013.06.051 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 900044 doi: 10.1016/j.physa.2013.06.051 lyricists_name: Benson, Philip lyricists_name: Michas, Georgios lyricists_name: Sammonds, Peter lyricists_id: PMBEN89 lyricists_id: MICHA38 lyricists_id: PRSAM22 actors_name: Jayawardana, Anusha actors_id: AJAYA51 actors_role: owner full_text_status: public publication: Physica A: Statistical Mechanics and its Applications volume: 392 number: 20 pagerange: 5172-5178 pages: 7 issn: 1873-2119 citation: Vallianatos, F; Michas, G; Benson, P; Sammonds, P; (2013) Natural time analysis of critical phenomena: The case of acoustic emissions in triaxially deformed Etna basalt.
