Physical constraints for effective magma-water interaction along volcanic conduits during silicic explosive eruptions

Comparison between resulting eruptive dynamics of phreatomagmatic eruptions and the equivalent simulations with no aquifer (i.e., using the same input values for water content at conduit bottom, inlet overpressure and conduit radius), as a function of the mass fraction of external water entered into the conduit. (a) Ratio of mass…

Observation and analyses of shear wave splitting at the Larderello-Travale geothermal field, Italy

Fig. 1. Map of seismicity recorded during the GAPSS experiment. Epicenters are represented by dots, whose size is proportional to magnitude and color represents depth according to the colorbar at the bottom left. Black triangles represent seismic stations used in this study. Black arrows indicate the direction of…

Evolution of shear zones through the brittle-ductile transition: The Calamita Schists (Elba Island, Italy)

Simplified geological map of southeastern Elba Island (modified after Papeschi et al., 2017). Squares highlight the location of the two studied sections. CNT: Capo Norsi thrust. CSZ: Calanchiole shear zone. FSZ: Felciaio shear zone. ZF: Zuccale fault. Mineral abbreviations: Ab: albite; And: andalusite; Bt: biotite; Crd: cordierite; Di: diopside; Wmca:…
