Fig. 4: Comparison of the recovery of the dv/v at the end of the 2017 and 2018 wet seasons.
From: Rain and small earthquakes maintain a slow-moving landslide in a persistent critical state
dv/v variations in the landslide material, obtained by comparing daily seismic noise correlograms in the 3–8 Hz frequency range in 2017 (a) and 2018 (b), together with all earthquakes reported by the IGP institute in Peru that have a PGV recorded at the landslide site above 0.01 cm.s−1 (cross mark) in 2017 (a) and 2018 (b). In addition, the PGV of earthquakes strong enough to saturate the seismometer placed on the landslide were estimated (dots) (see Methods for details).
