Contribution of volcanic ashes to the regional geochemical balance: The 2008 eruption of Chaitén volcano, Southern Chile

“…Beside the trace elements available these ashes are also provided with macro and micronutrients (Mn, Mg and Fe) evidencing the fertilising potential of the ashes. Although the total contributions of such elements are relatively low in ashes, their deposition could provide an external critical nutrient source in low nutrient areas [6].…”

“…Related of that there are several studies of the characterization of volcanic ash., F. Ruggieri, et al (2012) reflect their host [6]. The other study had been done by Bonnie Canion, et al (2012) that found of trace elements in volcanic ash from Mount Merapi, such as As, Co, Cr, Sb, V, Zn [7].…”

22, 19.63, 20.34, 3.86, and 2.57 ppm respectively. The results of the elemental contents of volcanic ash that has been obtained can be used as the scientific based data for volcanic material utilization by considering the economic potential of elements contained and also the danger of the heavy metals content. IntroductionMount Sinabung is a stratovolcano, located in Karo Regency, North Sumatra Province of Indonesia. It is a solitary volcano that has a single peak, and classified as B -Type, because since the 1600's there was no record of eruptive activity [1]. But on November 24, 2013, Mount Sinabung were erupted and reach the highest alert level (level 4) since it spat out black and thick smog, followed by rain sand and volcanic ash which covered thousands of hectares of farmer crops under the radius of six kilometers [2]. Volcanic ash is fragments of magma and consists of mineral, volcanic glass and also a material containing high silica and aluminum [2,3]. The composition of particles from volcanic eruptions should reflect the matrix composition of the magma. 06, 14.66, 1.88, 0.07, 0.6, 1.99, 4.18, 2.89, 0.2 % respectively [5]. These materials in the ash can provide important information on the nature of magma because chemical compositions of magma usually show distinct features of each volcano and because the assemblages and compositions of minerals

“…Substantial pasture and cropland downwind were coated with <1 mm to as much as 10 mm of fine tephra fall leading to crop and livestock loss; ingestion of ash by livestock led to fungal infections and tooth wear (Wilson et al, 2009b). Studies of downwind environmental impacts show that the tephra fall released a number of volatile trace elements to the environment that resulted in significant, but ephemeral, compositional changes in the biogeochemistry of soil, biota, and lakes in the region Ruggieri et al, 2012). Concentrations of several volatile trace elements (B, Cd, Zn, Tl, Cu, Ni) were positively correlated with tephra fall thickness.…”

ABSTRACT. Chaitén Volcano erupted unexpectedly in May 2008 in one of the largest eruptions globally since the 1990s. It was the largest rhyolite eruption since the great eruption of Katmai Volcano in 1912, and the first rhyolite eruption to have at least some of its aspects monitored. The eruption consisted of an approximately 2-week-long explosive phase that generated as much as 1 km 3 bulk volume tephra (~0.3 km 3 dense rock equivalent) followed by an approximately 20-month-long effusive phase that erupted about 0. RESUMEN. Revisión del volcán Chaitén y su erupción 2008-2009. Chile. El volcánChaitén entró en erupción inesperadamente en mayo de 2008 generando una de las mayores erupciones globales desde la década de 1990. Esta fue la mayor erupción riolítica desde la gran erupción del volcán Katmai en 1912 y la primera de este tipo en que al menos algunas de sus fases fueron instrumentalmente monitoreadas. La erupción consistió en una fase explosiva de aproximadamente 2 semanas de duración que generó un volumen de 1 km 3 de tefra (~0,3 km 3 equivalente roca densa), seguida por una fase efusiva de aproximadamente 20 meses de duración que evacuó alrededor de 0,8 km 3 de lava riolítica de alto contenido de sílice, lo que formó un nuevo domo dentro de la caldera del volcán. Hasta el inicio de este evento, se sabía poco sobre la historia eruptiva del volcán o los peligros que este imponía a la sociedad. Esta edición de Andean Geology contiene una selección de artículos que ofrecen nuevas perspectivas sobre la historia eruptiva del volcán Chaitén y el amplio espectro de nuevos conocimientos obtenidos del estudio de la erupción de 2008-2009. Aquí resumimos la configuración geográfica, tectónica y climática de este volcán y el estado del conocimiento previo para proporcionar un contexto a los artículos de esta edición, junto con una cronología revisada de la erupción de
