Explosive volcanic eruptions are defined as the violent ejection of gas and hot fragments from a vent in Earth's crust. Knowledge velocity is crucial for understanding modeling relevant physical processes an eruption, yet direct measurements still difficult task with largely variable results. Here we apply pioneering high‐speed imaging to measure pyroclasts Strombolian explosive unparalleled temporal resolution. Measured supersonic velocities, up 405 m/s, twice higher than previously...
The Campi Flegrei caldera (Italy) is among the most productive volcanoes of Mediterranean area. However, volcanic history preceding VEI 7 Campanian Ignimbrite eruption (~40 ka) still poorly constrained. Here, we use a tephra dispersal model to reconstruct source parameters Maddaloni/X-6 (~109 ka), one widespread Late Pleistocene marker from Flegrei. Our results suggest that was characterized by an early Plinian phase involving ~6 cubic kilometers (within range 3–21 kilometers) magma,...
We have refined the clinopyroxene-based hygrometer published by Armienti et al. (2013) for a better quantitative understanding of role H2O in differentiation Etnean magmas. The original calibration data set has been significantly improved including several experimental clinopyroxene compositions that closely reproduce those found natural products. To verify accuracy model, some randomly selected external to used as test data. Through statistic algorithm based on Mallows' CP criterion, we...
Abstract This multi-disciplinary work provides an updated assessment of possible future eruptive scenarios for the city Rome. Seven new 40 Ar/ 39 Ar ages from selected products Monti Sabatini and Vulsini volcanic districts, along with a compilation all literature on Colli Albani Vico products, are used to reconstruct compare histories over last 900 ka, in order define their present state activity. Petrographic analyses dated units characterize crystal cargo, Advanced-InSAR analysis...
The Campi Flegrei (CF) caldera, in southern Italy, is the source of some most powerful Late Pleistocene eruptions European sub-continent (e.g., Campanian Ignimbrite, Neapolitan Yellow Tuff eruptions). Although CF caldera has been continuously and intensively investigated for decades, relatively little known regarding its earliest volcanic activity. In this work, integrating existing new tephrostratigraphic data, we provide a comprehensive updated framework activity which occurred at ∼160 ka...
Abstract A new image processing technique—Pyroclast Tracking Velocimetry—was used to analyze a set of 30 high‐speed videos Strombolian explosions from different vents at Stromboli (Italy) and Yasur (Vanuatu) volcanoes. The studied invariably appear result the concatenation up hundred individual pyroclast ejection pulses. All these pulses share common evolution over time, including (1) non‐linear decrease velocity, (2) an increasing spread angle, (3) size ejected pyroclasts. These features...
Cyclic fluctuations in the frequency and intensity of volcanic activity are recorded during periods global climate change. Volcano-sedimentary successions (e.g., near-coastal environments) may reveal interplay glacio-eustatic fluctuations, controlling erosional vs. aggradational processes, pattern activity. However, idea a causal link between Earth’s volcanism is still debated, also because many prior studies have focused on single glacial cycle. The strongest evidence for connection...
