“…Figure 6 illustrates that radial distances from earthquake epicenters at which gravitational processes are triggered are roughly one order of magnitude higher at Cerro Crestón than in those cases presented in the literature 2,60 . In their assessments of impacts of moderate- and low-magnitude seismic activity in Spain and Mexico, different studies 61,62 reported that epicenter distance and area affected by co-seismic mass movements, even if small in nature, were well above the global bounds previously reported in the literature. In our case, the potentially causal relation between seismicity and rockfalls in the Southern Patagonian Cordillera suggests a triggering of rockfalls through ground acceleration, which is possibly enhanced through the amplification of ground motion on mountain tops 63 and the geometry of the local thrust-and-fault belt structures 64 , especially in case of seismic shaking around the Chilean Triple Junction (see Fig.…”

Earthquakes with magnitudes M > 7 can trigger large landslides and rockfalls at epicenter distances of up to 400 km, whereas moderate shaking ( M = 5–7) is generally thought to result in abundant co-seismic mass movements in the vicinity of the epicenter. Although one might anticipate that large magnitude earthquakes off the Chilean coast would result in abundant rockfall in the Patagonian Cordillera, only limited research has explored this hypothesis. Here, we use tree-ring records from 63 cross-sections of century-old (103.9 ± 40.1 yr) Nothofagus pumilio trees to develop a calendar-dated record of small rockfall events (10 1 –10 2 m 3 ) on a talus slope located next to Monte Fitz Roy (El Chaltén, Argentina; 49°4′S, 72°57′W). The resulting rockfall record is used to infer that subduction zone seismicity at the Triple Junction and intraplate shaking around Lago Argentino almost systematically caused rockfall activity at this site, even if seismicity occurred at large distances (up to 300 km away) and with moderate intensity ( M = 5–7). About one third of the rockfalls are triggered by factors other than earthquakes, predominantly in spring when freeze-thaw cycles occur frequently at the site. Despite the fact that seismicity is not the only trigger of rockfall activity at Cerro Crestón, at the foot of Monte Vespignani, we conclude that, in regions where topographic amplification plays a role, small rockfalls can be triggered by earthquakes of moderate intensity at large distances from the epicenter.

“…La modificación del perfil costero depende de la magnitud y periodicidad de los deslizamientos de tierra, que en muchas ocasiones es inducido por una secuencia sísmica, tal como se documentó en el estudio de caso del "Cañón de Santa Rosa" al noreste de México, que como parte de su metodología de investigación se estableció la necesidad de recopilar los movimientos telúricos registrados en las estaciones sismológicas cercanas al área de estudio, detallando la fecha, hora, magnitud y ubicación del epicentro (Salinas-Jasso et al, 2018). Las características geológicas conjugadas con el efecto de los movimientos telúricos del suelo aumentan el riesgo de deslizamientos de tierra (Yamagishi & Yamazaki, 2018).…”

La presente indagación bibliográfica pretende sintetizar información de las bases de reseñas de actividades científicas referente a la dinámica de la morfología de los acantilados a nivel mundial, mediante la recopilación de datos como: referencia bibliográfica, ubicación geográfica, método utilizado en la obtención de la tasa de retroceso, tipos de suelos que reflejan factores intrínsecos como las características físico-mecánicas, mineralógicas, geológicas y geomorfológicas, y factores extrínsecos entre los que podemos citar precipitaciones, clima, fuerza de los vientos, temperatura, acciones químicas del medio ambiente y en especial el cambio climático, que intervienen en la modificación de los acantilados de la línea de costa como consecuencias de erosiones sucesivas y deslizamientos. De la información recabada se obtuvo detalles de cinco países europeos, tres asiáticos, tres africanos, siete de América Latina y uno de Oceanía cuyos datos se encuentran plasmados en POWER ArcGIS. Concluyendo que el continente europeo tiene más información porque posee un sistema de satélites que es controlado por un programa
