Abstract: A model of magma flow-up through a set of fissure channels during the Great Tolbachik Fissure Eruption observed in Kamchatka in 1975 is suggested. The model is based on the assumption that the magmatic liquid flowing through fissure channels in the lithosphere experiences the Brinkman hydrodynamic resistance. Relationships between the depth of a magmatic source, time of magma flow-up to the Earth’s surface, and velocity of the magma flow through fissure channels to the Earth’s surface are derived.
