Volcanic activity can enhance several secondary effects, including the formation of one or more natural dams. A common example is from volcanic collapse, where huge mass volumes are rapidly emplaced, obstructing the drainage around a volcano. Their duration depends on the volume of the obstructing mass, inflow rate, and on its textural characteristics. A block facies of a debris avalanche produces durable and permeable dams that consist of decimeter to meter-sized blocks without matrix, whereas… Expand
Volcanic Natural Dams Associated with Sector Collapses: Textural and Sedimentological Constraints on Their Stability
The collapse of a volcanic edifice can enhance several secondary effects, including the formation of one or more natural dams. Their duration depends on the volume of the obstructing mass and on itsExpand
Source to sink: A review of three decades of progress in the understanding of volcaniclastic processes, deposits, and hazards
Abstract Volcaniclastic sediments, broadly defined as clastic deposits derived from the transport, deposition and/or redeposition of the products of volcanic activity, have long been a Cinderella ofExpand
The rain-triggered Atenquique volcaniclastic debris flow of October 16, 1955 at Nevado de Colima Volcano, Mexico
Abstract On October 16, 1955, at 10:45 a.m. (local time), after three days of intense rain (140 mm) that was twice the monthly average precipitation, a devastating flood surge formed a volcaniclasticExpand
Volcano-Hydrologic Hazards from Volcanic Lakes
Volcanic regions typically host multiple lakes developed in explosion craters, volcano-tectonic collapse structures, and valley systems blocked as a result of eruptive activity, their boundaries andExpand
The formation and impact of landslide dams – State of the art
Abstract The blocking of river courses by mass movements is very common in mountainous areas with deep and narrow valleys. Landslide dams may pose serious threats to people and their livelihoodsExpand
Volcanic Influence over Fluvial Sedimentation in the Cretaceous Mcdermott Member, Animas Formation, Southwestern Colorado
Volcanic processes during and after an eruption can impact adjacent fluvial systems by high influx rates of volcaniclastic sediment, drainage disruption, formation and failure of natural dams,Expand
Fault textures in volcanic debris-avalanche deposits and transformations into lahars: The Pichu Pichu thrust lobes in south Peru compared to worldwide avalanche deposits
Abstract Structures, lithofacies and semi-quantitative sedimentological analysis of volcanic debris-avalanche deposits are essential to constrain syn-emplacement processes along avalanche fault zonesExpand
The history and dynamics of a welded pyroclastic dam and its failure
The 2,360 BP eruption of Mount Meager, British Columbia began as an explosive, dacitic sub-Plinian eruption that waned rapidly to a sustained period of Vulcanian, eruption-triggered dome collapseExpand
Sector collapse of the SW flank of Volcán de Colima, México: The 3600 yr BP La Lumbre–Los Ganchos debris avalanche and associated debris flows
Abstract Some 3600 years ago the SW flank of Volcan de Colima collapsed, generating a debris avalanche that travelled 25 km to the Armeria River and stopped against the Cerro Grande limestoneExpand
The ~ 2500 yr B.P. Chicoral non-cohesive debris flow from Cerro Machín Volcano, Colombia
Abstract Cerro Machin Volcano (CMV) is located in the central part of the Colombian Andes (2750 m asl), 150 km southwest of Bogota. It is considered the most dangerous active volcano of Colombia. CMVExpand


The formation and failure of natural dams
Of the numerous kinds of dams that form by natural processes, dams formed from landslides, glacial ice, and late-neoglacial moraines present the greatest threat to people and property. Landslide damsExpand
Landslide Dams : Processes, Risk, and Mitigation
Landslide dams have proved to be both interesting natural phenomena and significant hazards in many areas of the world. A few of these blockages attain heights and volumes that rival or exceed theExpand
The cohesive Naranjo debris-flow deposit (10 km3): A dam breakout flow derived from the Pleistocene debris-avalanche deposit of Nevado de Colima Volcano (México)
Abstract Mass movement processes on volcanic terrains such as landslides and debris avalanches can cause the obstruction of main drainages producing the formation of temporary dams. A good example ofExpand
Reappraisal of the 1982 eruptions of El Chichón Volcano, Chiapas, Mexico: new data from proximal deposits
Abstract Additional data from proximal areas enable a reconstruction of the stratigraphy and the eruptive chronology of phases III and IV of the 1982 eruption of El Chichón Volcano. Phase III beganExpand
Geological constraints on the emplacement mechanism of the Parinacota debris avalanche, northern Chile
Abstract The Holocene Parinacota Volcanic Debris Avalanche (ca. 8,000 years B.P.) is located in the central Andes of northern Chile. The avalanche formed by the sector collapse of a majorExpand
Formation and failure of volcanic debris dams in the Chakachatna River valley associated with eruptions of the Spurr volcanic complex, Alaska
Abstract The formation of lahars and a debris avalanche during Holocene eruptions of the Spurr volcanic complex in south-central Alaska have led to the development of volcanic debris dams in theExpand
The 26 May 1982 breakout flows derived from failure of a volcanic dam at El Chichón, Chiapas, Mexico
The eruptions of El Chichon between 28 March and 4 April 1982 produced a variety of pyroclastic deposits. The climactic phase, on 3 April at 07:35 (4 April at 01:35 GMT), destroyed the centralExpand
Rock avalanching into a landslide-dammed lake causing multiple dam failure in Las Conchas valley (NW Argentina) — evidence from surface exposure dating and stratigraphic analyses
Generally landslide dams which exist for several hundreds to thousands of years are considered as stable. We show with an example from the Argentine Andes that such dams can exist for severalExpand
Paleohydrology and sedimentology of a post–1.8 ka breakout flood from intracaldera Lake Taupo, North Island, New Zealand
Sudden releases of impounded water from lakes in volcanic regions constitute a major and frequently repeated hazard. An outburst flood from Taupo caldera, New Zealand, released ∼20 km 3 of water,Expand
Prediction of the behaviour of landslide dams using a geomorphological dimensionless index
Landslide dams are a common phenomenon. They form when a landslide reaches the bottom of a river valley causing a blockage. The first effect of such a dam is the infilling of a lake that inundatesExpand
