Morakot-driven rainfall and landslides in Taiwan. (a) Hillshaded map of cumulative rainfall during typhoon Morakot (7–9 August 2009), obtained by interpolation of data from local weather stations (colored dots). (b) Digital elevation model of Taiwan with location of mapped landslides triggered by typhoon Morakot. Circle size and color indicate the surface area of a landslide, while the magenta line delimits the area with highest spatial density of landslides (see “Methods” section, Supplementary Fig. S2), referred to as the landsliding zone. Solid and dashed red lines indicate active thrust and strike-slip or normal faults, respectively²². Other less well identified faults exist inside the range²⁷. (c) Probability density distribution of the surface area of landslides triggered by typhoon Morakot for areas greater than 10 m². Maps were performed using Matlab R2019b.
