Disclosed is a method for manufacturing zeolite having excellent crystallinity using a volcanic eruption-induced material. The method for manufacturing zeolite according to the present invention comprises the steps of: (a) mixing an alkaline metal compound and a volcanic eruption - induced material and then melting the mixture; (b) adding an aluminum-based additive to the resultant of step (a) followed by stirring and aging the same; and (c) crystallizing the aged mixture, wherein the alkaline metal compound and the volcanic eruption - induced material are mixed at a weight ratio of 0.6:1 to 2.4:1.
