Logarithmic ESP distributions coloured by magma type. From top to bottom rows: Duration [h], Mass eruption rate [kg/s] and Column height above vent [km]. The diagonal panels show the empirical cumulative distribution functions; upper triangular panels show the distributions between pairs of ESPs; lower triangular panels show the same distributions interpolated using kernel density estimation (KDE). For the KDE gaussian kernels were used with the bandwidth computed using a heuristic described by Scott (1992). Contours are drawn at 0.1 intervals between 0 and 1
