Abstract.In this paper we use a Markov chain model and real data of volcanic activity from Volcán de Colima-Mexico to estimate the probability of having a volcanic activity of interest with a given intensity. The data used here correspond to the activity pattern during the years 1893-1905. We assume that successive activities presented by the volcano follow a Markov chain of order . This order is considered a random variable assuming values on a suitable set. Using a Bayesian approach we estimate the most likely order of the chain and the respective transition matrix. Based on these results the probability of having an activity with an intensity of interest is estimated.
