Recent eruptive activity at Stromboli is mostly characterized by persistent, Strombolian explosive activity from summit craters. Occasionally, so-called major explosions occur, and more rarely paroxysms take place, such as on 3 July and 28 August 2019. We analyze monitoring data recorded between 2016 and 2022 to identify and characterize patterns in multi-parameter time series (considering in particular seismic, geochemical, meteorological, and sea-level gauges), with special interest in analyzing patterns observed before and during the occurrence of major explosions and/or paroxysmal eruptions. In practice,(i) we implement algorithms to automatically identify families of seismic events using waveform features;(ii) we analyze the effect of oceanic microtremor on continuous and discrete amplitude-based measurements;(iii) we study the temporal and size distribution of event occurrences, and use this …
