Short summary
Tephra is fragmented material produced by explosive volcanic eruptions. Geochemically characterized tephra layers are excellent time marker horizons and samples of magma composition. TephraKam is database of the ages and chemical composition of volcanic glass in tephra from the Kamchatka volcanic arc (northwestern Pacific). TephraKam enables the identification of tephra sources, correlation and dating of natural archives, and reconstruction of spatiotemporal evolution of volcanism in Kamchatka.
