Fig. 2: Empirical frequency density distributions of rainfall duration, D (h) and hourly cumulated rainfall, E (mm) for 780,766 rainfall events in Italy obtained through Two-Dimensional Kernel Density Estimation, KDE2d79.
From: Deep learning forecast of rainfall-induced shallow landslides

Violet shows density for 2472 rainfall events from February 2002 to December 2020 for which the occurrence of at least one landslide is known. Blue shows density for 778,294 rainfall events for which the occurrence of landslide is not known. Upper and right plots show marginal distributions of D and E (violet and blue areas), and related empirical cumulative distribution functions, ECDF (violet and blue lines) normalised to the number of rainfall events with and without landslides, respectively.
