Para determinar el efecto de la actividad eruptiva en el régimen glaciar, se realizaron balances de masa empleando técnicas fotogramétricas, mediante la generación de modelos digitales de elevación (MDE). La compa- ración de MDEs permitió establecer los cambios glaciares en términos de área y volumen tanto temporales como espaciales. Así mismo, los cambios morfológicos del área glaciar fueron determinados con base en la fotointerpretación, de manera que los datos obtenidos por este procedimiento y los obtenidos mediante la comparación de los MDE se relacionaron con la actividad eruptiva a lo largo del periodo de estudio, estableciendo así la relación entre los fenómenos volcánicos y los cambios glaciares.

  • Volcanology: Electric Eruption
    news & views VOLCANOLOGY Electric eruption On the morning of 24 August, ad 79, Mount Vesuvius in the Bay of Naples, Italy, exploded into activity. The eruption caught the roman occupants of Pompeii and Herculaneum utterly unawares. The cities were rapidly buried by thick ash fall and pyroclastic surges, killing thousands of people. In a letter to the historian Tacitus, Pliny the Younger, an eyewitness and survivor of the eruption, described “frightening dark clouds, rent by lightning twisted and hurled” (http://go.nature.com/gkcLgn). Volcanic lightning has since been documented during many historical eruptions. More recently, spectacular lightning was observed during the eruptions of Mount Redoubt in Alaska, USA, in 2009 and Eyjafjallajökull Volcano in Iceland in 2010. The lightning generally occurs within the volcanic plume — a spreading column of ash, rock and hot gases blasted from the volcano vent. Although the details of the processes are poorly understood, volcanic lightning is thought to be triggered by the fragmentation of, and high-speed collisions between, volcanic rocks and ash as they exit the vent, as well as by the interactions between super-cooled water / ALAMY IMAGES © ARCTIC droplets and ice particles in higher, cooler parts of the column. The collisions create positive and negative electrically charged analysed ash deposits collected from The glass spherules mostly formed regions within the volcanic plume that are the Mount Redoubt and Eyjafjallajökull from melting of the smallest individual ash equalized by an electrical discharge that eruptions and found tiny glass spherules grains or from the fusion of several melted creates a lightning flash.

  • Historically Active Volcanoes of Alaska Reference Deck Activity Icons a Note on Assigning Volcanoes to Cards References
    HISTORICALLY ACTIVE VOLCANOES OF ALASKA REFERENCE DECK Cameron, C.E., Hendricks, K.A., and Nye, C.J. IC 59 v.2 is an unusual publication; it is in the format of playing cards! Each full-color card provides the location and photo of a historically active volcano and up to four icons describing its historical activity. The icons represent characteristics of the volcano, such as a documented eruption, fumaroles, deformation, or earthquake swarms; a legend card is provided. The IC 59 playing card deck was originally released in 2009 when AVO staff noticed the amusing coincidence of exactly 52 historically active volcanoes in Alaska. Since 2009, we’ve observed previously undocumented persistent, hot fumaroles at Tana and Herbert volcanoes. Luckily, with a little help from the jokers, we can still fit all of the historically active volcanoes in Alaska on a single card deck. We hope our users have fun while learning about Alaska’s active volcanoes. To purchase: http://doi.org/10.14509/29738 The 54* volcanoes displayed on these playing cards meet at least one of the criteria since 1700 CE (Cameron and Schaefer, 2016). These are illustrated by the icons below. *Gilbert’s fumaroles have not been observed in recent years and Gilbert may be removed from future versions of this list. In 2014 and 2015, fieldwork at Tana and Herbert revealed the presence of high-temperature fumaroles (C. Neal and K. Nicolaysen, personal commu- nication, 2016). Although we do not have decades of observation at Tana or Herbert, they have been added to the historically active list.

Statements of significance describe why an area is important within a global, national, regional, and systemwide context. These statements are linked to the purpose of the park unit, and are supported by data, research, and consensus. Significance statements describe the distinctive nature of the park and inform management decisions, focusing efforts on preserving and protecting the most important resources and values of the park unit. Fundamental resources and values are those features, systems, processes, experiences, stories, scenes, sounds, smells, or other attributes determined to merit primary consideration during planning and management processes because they are essential to achieving the purpose of the park and maintaining its significance.
