Integrating global geochemical volcano rock composition with eruption history datasets

The major element composition of volcanic rocks carries important information about the source and differentiation processes affecting magma, physical properties that allow it to erupt, its eruptive style. Although global rock geochemical databases exist, these are not linked eruption history which hampers our understanding relationship between magma dynamics. Here, we integrate two databases, Geochemistry Rocks Oceans Continents (GEOROC) Holocene volcanoes world Global Volcanism Program (VOTW-GVP). integration is based on matching location name, geographic position time, automated by a tool called DashVolcano. open-source, accessible at https://github.com/feog/DashVolcano , gives access integrated datasets via an interactive dashboard. DashVolcano more than 138,000 samples provides basis for identification relationships styles, volcano types, 700 their eruptions last 10,000 years. combined record corresponding can be used characterizing differences volcanoes, should also prove useful improved long-term hazard risk evaluations.
