Eruptions listed within the database presented as a function of latitude. Eruptions are colour-coded by their proximity to the nearest ocean using distances (a) \(D\) or (b) \({D}_{PDA}\). White triangles (grey outline) mark eruptions for which the primary dispersal axis is not known. For both panels (a) and (b), the eruptions exhibiting the largest and smallest values are labelled. Age is presented on a logarithmic axis, given that the majority of eruptions listed in the database are those that occurred since < 1 Ma
