“…The broad vesicularity range for the lapilli and bombs (Φ between 0.21 and 0.89) from the 2014–2015 eruption is consistent with data obtained from other Surtseyan eruptions (Cole et al, ; Jutzeler et al, ; Murtagh et al, , ).…”

“…For fire‐fountaining activity or bread‐crust bombs from Vulcanian eruptions Colombier et al () proposed that low average but broad ranges in connectivity may reflect quenching hindering postfragmentation vesiculation. The gradual textural variations observed in the Tongan transitional, rim‐to‐core profiles are similar to those seen in scoria from fire‐fountaining eruptions (e.g., Stovall et al, ), bread‐crust bombs from Vulcanian eruptions (Giachetti et al, ; H. M. N. Wright et al, ), or pyroclasts from shallow or deep subaqueous eruptions (e.g., Jutzeler et al, ; Schipper et al, ). The rims in such specimens preserve low vesicularity and small, isolated vesicles, inferred to represent the state of the magma at the point of fragmentation.…”

“…The vesicle number densities of the Tongan lapilli and bombs (Table ) have values typical of shallow subaqueous mafic eruptions (Jutzeler et al, ), and the values are similar using either 2‐D or 3‐D methods for sample HH37‐3 (Table ). However, there are discrepancies in the VSD in 2‐D and 3‐D measurements.…”

Surtseyan eruptions are shallow to emergent subaqueous explosive eruptions that owe much of their characteristic behavior to the interaction of magma with water. The difference in thermal properties between water and air affects the cooling and postfragmentation vesiculation processes in magma erupted into the water column. Here we study the vesiculation and cooling processes during the 2009 and 2014-2015 Surtseyan eruptions of Hunga Tonga-Hunga Ha'apai volcano by combining 2-D and 3-D vesicle-scale analyses of lapilli and bombs and numerical thermal modeling. Most of the lapilli and bombs show gradual textural variations from rim to core. The vesicle connectivity in the lapilli and bombs increases with vesicularity from fully isolated to completely connected and also increases from rim to core in transitional clasts. We interpret the gradual textural variations and the connectivity-vesicularity relationships as the result of postfragmentation bubble growth and coalescence interrupted at different stages by quenching in water. The measured vesicle size distributions are bimodal with a population of small and large vesicles. We interpret this bimodality as the result of two nucleation events, one prefragmentation with the nucleation and growth of large bubbles and one postfragmentation with nucleation of small vesicles. We link the thermal model with the textural variations in the clasts-showing a dependence on particle size, Leidenfrost effect, and initial melt temperature. In particular, the cooling profiles in the bombs are consistent with the gradual textural variations from rim to core in the clasts, likely caused by variations in time available for vesiculation before quenching. Wilding et al. Key Points:• Lapilli and bombs from Surtseyan eruptions show gradual textural variations due to the quenching in water • The kinetics of magma cooling during Surtseyan eruptions are influenced by particle size, radial position, and Leidenfrost effect • The 3-D analysis of vesicle metrics using X-ray microtomography allows quantification of the percolation threshold in volcanic rocksSupporting Information:• Supporting Information S1Correspondence to: M.

“…We conclude that (a) fall deposits reduce their thickness moving away from the vent(s), as expected, and (b) volcanoclastic flow deposits emplace in proximal areas alone. The shape and amount (35-40 vol.%) of bubbles of the MS1 and of MS2 ash are similar to those observed in ash-sized pyroclasts from subaerial Strombolian and phreatomagmatic eruptions 21 and significantly lower than that of subaerial and deep submarine silicic eruptions 8 . Subaerial Strombolian and phreatomagmatic eruptions have bubble content generally between 20 and 40 vol.% (e.g.…”

“…Subaerial Strombolian and phreatomagmatic eruptions have bubble content generally between 20 and 40 vol.% (e.g. Kilauea Iki, Miyakejima) with few examples of larger, up to 80 vol.%, contents (e.g., Stromboli paroxysms and Mauna Ulu lava fountains) 21 . Most of pyroclasts from subaerial plinian and deep submarine silicic eruptions has bubble content in the range 40-90 vol.% 21 .…”

The dynamics of deep sea explosive eruptions, the dispersion of the pyroclasts, and how submarine eruptions differ from the subaerial ones are still poorly known due to the limited access to sea environments. Here, we analyze two ash layers representative of the proximal and distal deposits of two submarine eruptions from a 500 to 800 m deep cones of the Marsili Seamount (Italy). Fall deposits occur at a distance of more than 1.5 km from the vent, while volcanoclastic flows are close to the flanks of the cone. Ash shows textures indicative of poor magma-water interaction and a gas-rich environment. X-ray microtomography data on ash morphology and bubbles, along with gas solubility and ash dispersion models suggest 200-400 m high eruptive columns and a sea current velocity <5 cm/s. In deep sea environments, Strombolian-like eruptions are similar to the subaerial ones provided that a gas cloud occurs around the vent.
