EUROVOLC Virtual Access to computational tools at INGV Pisa

While computational capabilities in volcano science are developing to progressively higher sophistication levels involving HPC, parallel programming, and extensive use of super-computers, there is an increasing demand for accessibility to low to intermediate-level models and codes that can support multi-disciplinary research carried out by experts other than physical modelers and code developers. Responding to such a need by the international community is the justification and objective of Virtual Access (VA) activities developed under the EUROVOLC project. The Volcano Dynamics Computational Centre (VDCC) at INGV Pisa is renown as one international leader in physical-mathematical modelling and numerical simulation of volcanic thermo-fluid dynamics processes occurring from the deep regions of magma rise and accumulation within the crust, to within the atmosphere during volcanic eruptions. VDCC has been developing a large set of computational tools during last 30 years, that are offered under EUROVOLC for Transnational Access (for the most sophisticated, computational demanding models and codes) as well as for VA for low to intermediate-level models and codes. The latter include from non-ideal, compositional-dependent, multi-component volatile-melt thermodynamics to steady-state magma ascent to fast-performing kinematic modelling of pyroclastic density currents. Here we illustrate the model capabilities, the procedures to both download the codes and perform web-based computation, and a few relevant examples of calculations available through VA, and show relevant statistics of access and download by the volcano community to-date.
