Temporal analysis

Temporal analysis complements spatial analysis by establishing the relative temporal position of each eruption (volcanic stratigraphy) and, whenever possible, its geochronology by means of radiometric dating. This enables us to identify temporal patterns in the eruptive behaviour of the volcanic system such as clusters of eruptions or episodes of quiescence between eruptions and, if absolute ages are available, the eruption frequency or recurrence (i.e. the temporal probability of an eruption) (Sobradelo et al., 2013).
