Mass movement in Cordón de las Osamentas, de La Flecha river basin, San Juan, Argentina

Gravitational sliding of the carbonate megablocks in the Vipava Valley, SW Slovenia

“…The wider region is seismically still active, as earthquakes with magnitudes above 5.5 have been recorded in 10s km radius around the studied area (obtained from the earthquake catalogue of Slovenian Environment Agency (Internet 2 and 3) and comprising earthquakes younger than 1348). Such large events are known to be a major cause for major landsliding (Benac et al 2005;Shroder et al 2011;Esper Angillieri and Perucca 2013). The study area lies in an active seismic zone (Poljak, Živičič and Zupančič 2000;Placer, Vrabec and Celarc 2010), very close to the Predjama fault, between the Raša and Idrija faults (Vrabec and Fodor 2006).…”

A large and active debris-rockslide in the Central Andes of Argentina (30.26°S): Morphometry and triggering mechanisms

“…2 shows the DEMs showing pre and post failure topography. A similar method of topographical reconstruction, using the intersection lines of interpolated structural features, has been presented by Süzen and Doyuran (2004); Oppikofer (2009); Esper Angillieri and Perucca (2013) andEsper Angillieri et al (2014).…”

Morphometric characterization of a large scale rockslide, and probable seismogenic origin of landslides on the western flank of Central Precordillera, Argentina

“…Earthquakes are one of the main triggers that cause landslides. Earthquake induced landslides have been documented in Centralwestern Argentina (Perucca and Moreiras, 2006;Perucca and Esper Angillieri, 2008;Esper Angillieri and Perucca, 2013;among others). San Juan Province experiences around 20e30 earthquakes daily, although the majority of these earthquakes are not felt due to low magnitude.…”

“…He found relationships between the slope size and shape with the dominant wavelength favoring topographical amplification and landslide generation. Several authors have studied landslides in Argentina (Fauqué et al, 2000;Fernández, 2005;Moreiras, 2006;Esper Angillieri, 2008, 2009a,b;González Díaz, 2009;Esper Angillieri, 2011, 2012Esper Angillieri and Perucca, 2013) and in the Central Andes of Chile (Moreiras and Sepúlveda, 2009;Welkner et al, 2010;Sepúlveda et al, 2012), associating them with earthquakes.…”
