The Multifractal Detrended Fluctuation (MF-DF) algorithm is applied to measure the complexity of two time series, the inter-event hypocentral distance Δδ(t), and the inter-event time series Δτ(t) In particular, we apply this methodology to the se

Monthly rain amounts (MRA) recorded at Fabra Observatory (Barcelona, NE Spain) since 1917–2010, are analysed from two complementary points of view. First, mono- and multifractal characteristics of MRA are compared with those corresponding to the mo

The Dry Day Since Last Rain index, DDSLR, quantifies for every recording day the number of consecutive preceding days with daily rainfall below a threshold. In essence, DDSLR may quantify the hydrologic stress generated by consecutive days of rainfal
