Multiple magma recharges over prolonged period ultimately trigger eruptions at Vulcano, Aeolian Islands.
Giuffrida M., Salerno G., Viccaro M.
The compositional heterogeneity of clinopyroxene in products of the 1888-90 eruption at La Fossa of Vulcano has been used to constrain times of the plumbing system reactivation before the eruption. We have also investigated the temporal trend of the SO2...

Unique formation of organic glass from a human brain in the Vesuvius eruption of 79 CE
Giordano G., Pensa A., Vona A., Di Genova D., Al-Mukadam R., Romano C., Deubener J., Frontoni A., Petrone P.
Glass forms when a liquid is fast cooled preventing crystallization, across a reversible process known as the glass transition. Organic tissues are commonly preserved as glass by processes of vitrification at very low temperatures, known as cryopreservation,...

Sierra Negra, Galápagos: A resurgent-block basaltic caldera
Acocella V., Galetto F., Amelung F., Aguaiza S.
Caldera resurgence is rare at mafic volcanoes. Here we consider the well-exposed resurgence at Sierra Negra caldera (Galápagos) to investigate how resurgence develops at a mafic system. Based on topographic and field analysis, the structure of...

The use of high-resolution satellite topographic data to quantify volcanic activity at Raung volcano (Indonesia) from 2000 to 2021
Galetto F., Lobos-Lillo D., Pritchard M. E.
Quantifying erupted volumes of magma is fundamental to determine the size of eruptions. Pre- and post-eruptive digital elevation models (DEMs) derived from satellite data can quantify erupted volumes, even in remote areas. Here we used bistatic synthetic...

Grapevine rootstocks in K-and Ca-rich volcanic soils: The effect of mineral assemblage on nutrient uptake efficiency
Gaeta M., Pacheco P., Aldega L., Astolfi M.L., Giannessi E., Perinelli C.
This study examines element mobility in volcanic soils to evaluate the relationships between mineral assemblage and the uptake capacity of rootstocks. The Gravesac rootstock, which appears to have a low capacity to selectively absorb K, Ca, Mg, and Na...
