The volcano is located in the State of Nayarit, Mexico, 21,125° N and 104, 508° W, it has been characterized in the past by episodes of effusive-explosive eruptions. Nelson (1986) identifies the eruptions that have occurred, called the Jala eruption, which correspond on average to an eruption every 125 years, and proposes that new eruptions are very likely. In the study by Suárez-Plascencia (1998), with geological evidence, identified hazards near Ceboruco Volcano, such as lava flow, pyroclastic surges and ash fall based on the most recent eruption in 1870. The vulnerable populations and facilities in the affected area and according to the hazard were identified, with the criteria of CENAPRED (2011) and CEPAL (2016) with the information generated by INEGI. The high vulnerability corresponds to communities like Ahuacatlán, Ixtlán, Jala and Jomulco, and facilities are the highways and railways. Questionnaires were applied to know the perception about hazards by the Ceboruco Volcano in the mentioned communities. The greatest frequency in the responses of people were Ceboruco volcano hazards were unlikely to occur. Ahuacatlán is the only community that identifies one evacuation route toward Amatlán de Cañas in case of occurrence volcanic activity. The misinformation generated in social networks was a mayor problem and one imbalance for the Civil Defense work programs in the communities near the Ceboruco Volcano.
