The effect of dynamic loading on the shear strength of pyroclastic Ash Deposits and implications for landslide hazard: The case of Pudahuel Ignimbrite, Chile
(Elsevier, 2016)
The co-seismic and post-seismic behaviour of pyroclastic ash deposits and its influence on slope stability remains as a challenging subject in engineering geology. Case studies in volcanic areas of the world suggest that ...
The last step of the volcanic unrest in Turrialba volcano: a new stage of magmatic eruptions
(2015)
In 1864-1866, Turrialba volcano had a strombolian eruption with some phases of phreatic and phreatomagmatic activity, that covered the Central Valley of Costa Rica with a variable thickness of ash. During this eruption, ...
ATLAS-1.0: Atmospheric Lagrangian dispersion model for tephra transport and deposition
(Pergamon-Elsevier Science Ltd, 2019-05-20)
ATLAS-1.0 (ATmospheric LAgrangian diSpersion) is a new atmospheric dispersion and sedimentation Lagrangian model tailored to volcanic tephra/ash. The model solves the Advection–Diffusion–Sedimentation equation across ...
Mass flux decay timescales of volcanic particles due to aeolian processes in the Argentinian Patagonia steppe
(Nature, 2020-09)
We investigate the timescales of the horizontal mass flux decay of wind remobilised volcanic particles in Argentina, associated with the tephra-fallout deposit produced by the 2011–2012 Cordón Caulle (Chile) eruption. ...
The first fossil isopod from Argentina: A new species of Cirolanidae (Crustacea: Peracarida) from the Miocene of Patagonia
(Crustacean Society, 2018-01)
Cirolana centinelensis, a new species of fossil cirolanid isopod from the early Miocene of Argentina is described, and the fossil record of South American isopods is briefly reviewed. Few fossil isopods are known from South ...
Volcanic ash from Puyehue-Cordón Caulle eruptions affects running performance and body condition of Phymaturus lizards in Patagonia, Argentina
(Wiley Blackwell Publishing, Inc, 2016-08-18)
The Puyehue-Cordón Caulle eruption of 4 June 2011 dispersed about 100 million tonnes of pyroclastic materials resulting in ash accumulations of 30 cm depth on the Patagonian steppe, an area occupied by several lizard ...
Tormentas de ceniza volcánica en Patagonia : un peligro latente y subestimado
(2018-04)
Una tormenta de ceniza volcánica puede definirse como un evento de remobilización masiva de ceniza volcánica (<2mm) a partir de la acción eólica (via suspensión, saltación y reptaje). Pero, ¿a qué nos referimos exactamente ...
