Submarine Mass Movements and Their Consequences: Progress and Challenges

Abstract

This sixth edition of the Submarine Mass Movements and Their Consequences volume, coincident with the seventh eponymous conference includes 61 papers that span a variety of topics and are organized into nine parts as follows:(1) Submarine mass movement in margin construction and economic significance; (2) Failure dynamics from landslide geomorphology; (3) Geotechnical aspects of mass movement; (4) Multidisciplinary case studies; (5) Tectonics and mass movement processes; (6) Fluid flow and gas hydrates, (7) Mass transport deposits in modern and outcrop sedimentology; (8) Numerical and statistical analysis; and, (9) Tsunami generation from slope failure. The breath and quality of this body of work underpins a positive outlook and our enthusiasm for the future direction of research in this area of science as it moves towards ever more detailed analysis and monitoring. We also emphasize in this volume the need to look at mountain-scale

Morphology, age and sediment dynamics of the upper headwall of the Sahara Slide Complex, Northwest Africa: Evidence for a large Late Holocene failure

“…Submarine landslides are a widespread phenomenon documented in multiple geological settings such as tectonically active margins, passive continental margins and volcanic islands (Masson et al, 2006;Moernaut and De Batist, 2011;Krastel et al, 2014;Lamarche et al, 2016). Submarine landslides transport large volumes of sediments into deeper continental slope and abyssal areas, and some present sufficient density and speed to pose important hazards to anthropogenic structures in shallower water (Lo Iacono et al, 2012).…”

Carbonate slope re‐sedimentation in a tectonically‐active setting (Western Sicily Cretaceous Escarpment, Italy)

“…This variability makes it difficult to develop both depositional and stratigraphic models for hydrocarbon evaluation and hinders the enhancement of an accurate terminology to describe deposits in outcrop. In siliciclastic systems, MTDs are considered as good traps and seals, thus presenting an important reservoir feature (Beaubouef & Abreu, ; Kneller et al ., ; Lamarche et al ., ). In carbonate systems, giant hydrocarbon reservoirs have been discovered in Cretaceous slope successions worldwide (Borgomano, ), for example, the Poza Rica trend in Mexico (e.g.…”

Submarine landslide susceptibility assessment along the southern convergent margin of the Colombian Caribbean

“…Submarine landslides and MTCs have been studied worldwide in different geological settings McAdoo et al, 2000;Lamarche et al, 2016;. Consequences of submarine landslides can be significant in terms of loss of life , damage to coastal infrastructure and for the Oil and Gas industry where the costs can reach about US$ 400 million annually (Lamarche et al, 2016).…”

“…These phenomena play a significant role in the evolution of continental margins due to their ability to mobilize large volumes of rock, debris, or soil downslope (McAdoo et al, 2000;Lastras et al, 2005;Masson et al, 2006;Moscardelli and Wood, 2008;Morley and Leong, 2008;Locat and Lee, 2009;. Likewise, they have the potential to affect coastal infrastructure Kopf et al, 2010), submarine telecommunications cables (Hasegawa and kanamori, 1987), pipelines (Lamarche et al, 2016), and generate tsunamis and avalanches (Nadim et al, 2006;Abella and Van Westen, 2007;Devoli et al, 2007;Tappin, 2010;Randolph and White, 2012;Vanneste et al, 2013;Glimsdal et al, 2016;Leslie and Mann, 2016;Tappin, 2017;Arikawa, 2018;. The negative consequences of submarine landslides have been socially and economically significant Heidarzadeh M., 2018).…”
