Fig. 3. Annual landslide velocity as a function of effective annual rainfall.

Colors indicate the number of earthquakes with PGV at the landslide location above 0.01 cm.s⁻¹. See SI and Supplementary Fig. 6 for more information. The effective annual rainfall corresponds to the cumulative effective precipitation between December until mid-August of each year. The cumulative displacement for each year corresponds to the total displacement between the first and the last date of the rainy season were the landslide’s velocity is above a certain threshold (set at 0.039 m.yr⁻¹). Earthquakes are counted only in between 2 weeks prior to the acceleration of the landslide, up to when the motion ceases in each rainy season. The displacement and seismicity following the August 2016 earthquake are not taken into account for 2016. These periods are summarized in the Supplementary Fig. 6 and Supplementary Note 1.
