Statistical analysis of the long-range transport of the 2015 Calbuco volcanic plume from ground-based and space-borne observations
(Copernicus Publications, 2020-03)
This study investigates the influence of the 2015 Calbuco eruption (41.2∘ S, 72.4∘ W; Chile) on the total columnar aerosol optical properties over the Southern Hemisphere. The well-known technic of sun photometry was applied ...
Simulations of tephra dispersal from the 1991 explosive eruptions of Hudson volcano, Chile
(Elsevier Science, 2010-02)
The 1991 explosive eruptions of Hudson volcano in southern Chile produced 2.7 km3 (dense rock equivalent) of basalt and trachyandesite tephra during the period August 8-15. The initial basaltic phase (phase I, August 8-9) ...
Of volcanoes and insects: the impact of the Puyehue–Cordon Caulle ash fall on populations of invasive social wasps, Vespula spp.
(2013-03)
Las erupciones volcánicas tienen importantes efectos en los ecosistemas terrestres. Los efectos bióticos de ceniza volcánica en las poblaciones de insectos varian de un generalizado y catastróficoa lo sutil y localizada. ...
Impact of Chaitén Volcano ashfall on native and exotic fish recovery, recolonization, and abundance
(Elsevier, 2021-01)
The effects of volcanic disturbance on aquatic communities and their recovery are poorly studied. To fill this gap, we explored the effects on fish communities in rivers in Argentina of the 2008 eruption of Chaitén Volcano ...
C-band Dual-Polarization Radar Observations of a Massive Volcanic Eruption in South America
(Institute of Electrical and Electronics Engineers, 2017-01)
The eruption of Calbuco volcano on April 22-23, 2015 is the first volcanic eruption detected by a weather radar in South America. The detection was performed by the first domestically produced Argentinean weather radar, ...
Volcanic alert system by lightning detection using the WWLLN - ash cloud monitor
(Pergamon-Elsevier Science Ltd, 2021-06)
Electrical discharges are observed in many volcanic eruptions and they have often been used as indicators of such eruptions. Volcanic lightning is remarkably similar to those produced during thunderstorms and is called ...
