“…Over the last two decades, seismic signals generated by granular flows (e.g., landslides, debris flows, and rockfalls) have been investigated increasingly as a useful complementary tool to sparse visual observations, in order to detect flows and deduce informations about their localization and dynamics (e.g., Arattano, 2000;Brodsky et al, 2003;Dammeier et al, 2011;Durand et al, 2018;Huang et al, 2007;Hibert, Ekström, et al, 2017;Hibert, Mangeney, et al, 2017;Kean et al, 2015;Lai et al, 2018;Schöpa et al, 2018;Suriñach et al, 2005;Pérez-Guillén et al, 2016;Yamada et al, 2016;Zhao et al, 2015).…”
