The way people perceive the volcanic risk and how this leads them to take protective measures is an essential topic in volcanology. We apply the Protection Motivation Theory (PMT) to analyse the threat and coping appraisal of individuals living at different distance ranges from Volcán de Colima, Mexico. We assessed respondents’ perceived vulnerability, the severity of the volcanic threat, their perception of the efficacy of protection measures, their ability to implement them, and how this influences their level of implementation. We collected data from 224 individual inhabitants from twelve different villages. People living closer to the volcano have a higher threat appraisal but a lower level of implementation of protective measures. Perceived severity of the threat, the efficacy of the recommended measures, and the respondents' self-efficacy were significantly related to the implementation of protective measures. However, the relationship for self-efficacy was strongest. As such, risk management in the Colima area should focus on improving self-efficacy to enhance the implementation of protective measures. Priority should be given to communities closest to the volcano.
