Fig. 4: Average velocity of Earthquake Accelerated Landslides (EALs) in the study area estimated every three months.

a Times series of the 3-month mean velocity and corresponding precipitation. The red shading indicates the period of the 2016-2017 earthquake sequence, and the black vertical solid lines indicate the specific time of the four earthquakes. The colored rectangles at the bottom of (a) represent the number of earthquakes (M > 3.0) in their time windows. Note that the gray error bars are the standard deviations of all the EAL velocities and represent the velocity dispersion between EALs rather than a measure of the velocity accuracy. b Gridded average velocity of EALs during different phases.
