• Rainfall dynamics
• Event definition
• Drop-like nature
• Quiescent and active phases

In this manuscript, we show that 1) the rain event definition resting on the occurrence of a minimum rainless period and the one resting on a sequence of consecutive wet intervals are statistically equivalent. 2) It is possible to obtain a point based Eulerian event definition using the statistical properties of the inter drop time intervals These properties indicate the range [1.5, 4] h as the proper one for the choice of a minimum rainless period for Chilbolton, UK. 3) The intra event dynamical variability is "described" by an alternate sequence of quiescent and active phases.
