(2) these are average rates, whereas magma ascent and decompression are dynamic processes, which evolve from storage to surface, (3) the plot comprises many different types of eruptions of differing scales, e.g.
characterized by effusive eruptions that efficiently drained the storage system and emitted large volumes of magma; the second behavior is related to lava fountains, erupting small magma batches, which are normally with high frequency and have been considered as precursors of major effusive eruptions. ...
Pa?s are predicted to have been characterized by discharge rates of ~3?脳?107?m3/s for 25-km-wide flows, with associated mechanical incision rates of ~4?m/day and thermal incision rates of ~2?m/day. Formation of Aromatum Chaos and the preserved 215-km-long extent of Ravi Vallis is...
[1] Stromboli is an open conduit volcano characterized by persistent conduit degassing and explosive dynamics. During the 2003 effusive eruption we monitored this activity with a five-element array deployed at ∼450 m from the active craters. The array allows us to track in real time changes...
All the eruptions are triggered by deeper magma recharge ascending from storage pressures of ~4–5 kbar, leading to some rejuvenation of the shallow silicic mush. The most mafic recharges (~55 wt% SiO2, ~1000 °C, >3 wt% H2O) promote effusive eruptions after mixing and hybridizing the ...
In Sect. 2.16, the large-scale flood basalt eruptions of the Siberian Platform are discussed.doi:10.1007/978-94-007-5022-7_2Ryabov, V.V.Shevko, A.Ya.Gora, M.P.
fundamental periodicities in subsets of the 1922鈥 2021 time-series: (i) long term (ca. 10years), (ii) intermediate term (ca. 3.5years), and (iii) short term (from ca. 1year to ca. 3months), which are comparable with those observed at other lava dome eruptions at calc-alkaline ...
Swarms of microearthquakes (majority of them with magnitudes of about 0) have been recorded on different volcanoes of the world. They have been associated with effusive and explosive eruptions at volcanoes of all types: basaltic, andesitic, and dacitic. These swarm...
Swarms of microearthquakes (majority of them with magnitudes of about 0) have been recorded on different volcanoes of the world. They have been associated with effusive and explosive eruptions at volcanoes of all types: basaltic, andesitic, and dacitic. These swarms occur frequently just before ...
Since numerous phreatomagmatic pipes are present in these areas, we suggest a causal relationship between deep magma鈥搒ediment interactions, explosive eruptions and the resulting environmental stress that initiated the end-Permian mass extinction....
