A volcano eruption model is provided to improve education efficiency by vividly modeling eruption of a volcano by inserting mixed solution into the volcano eruption model. A volcano eruption model includes a volcano cross-section model(2), which is scaled down from a real volcano and made of a synthetic resin. Mixed solution container insertion holes(3,4) are formed at both sides of the volcano eruption model. A solution container(6) and a lava eruption hole(5) are coupled with the insertion holes. A lava guide groove is formed on the surface of the volcano cross-section model, so that the erupted solution is prevented from being ejected to the outside. The volcano cross-section model is held on a holder. A stepped portion(9) prevents the lava-solution from leaking out of the holder.
