Trekking Desolacion Trail. Volcán Osorno, Petrohué Falls,Emerald Lake. Trekking : Vicente Perez Rosales N.Park
Trekking Desolacion trail. Volcán Osorno, Petrohué falls,Emerald Lake. Trekking : Vicente Perez Rosales N.Park. Desolation Pass. Overview: Profile: Adventurous Difficulty level: medium. Season: November to late March Other trips you might find interesting: Solitario Hike Parque Nacional V, Perez Rosales. Cochamo Walls and river Hike, Tagua Tagua Hike. We depart early in mornig from Puerto Varas to Petrohué on the shores of Todos Los Santos Lake. On our way to the lake, we’ll pass through areas that are the mouths of the rivers which flow from the sides of Osorno Volcano. On warm days, it is possible to see what appear to be dust clouds arising from the flanks of the volcano. In reality, these are ash clouds raised by the flowing waters making their way down the flanks of the volcano. We will cross vast areas of black ash mixed with the lashes from the Calbuco eruption in 2015 and have been brought down by the glacial melt. You will appreciate the might of the volcano as you see the results of the ash flows experienced during its eruptions. One can only imagine what it must have been like during its periods of activity. Leaving Petrohué, we head upward toward the base of Volcano Osorno (8,730 feet). Our trek takes us through Osorno’s volcanic canyons where amazing rock formations are etched out of the canyon walls by the melting snows and glaciers of Osorno. As we head upwards to Desolation Pass, at an altitude of 5,610 feet between the Osorno and Cerro La Picada volcanoes, we will also see a wide variety of lava formations created by the lava flows that built Osorno. -

Boron and Other Trace Element Constraints on the Slab-Derived Component in Quaternary Volcanic Rocks from the Southern Volcanic Zone of the Andes

The dataset shows con- straints on the nature of slab-derived component to mantle source. Analyzed samples show large negative Nb and Ta anomalies, and enrichment of alkaline earth elements and Pb, which are features of typical island arc volcanic rocks. Boron contents of SVZ volcanic rocks range 2.3–125.5 ppm, exhibiting marked enrichment relative to N-MORB and OIB. Both the boron contents and B/Nb ratios of the volcanic rocks increase from the southern SVZ (SSVZ) to central SVZ (CSVZ). Fluid mobile/immobile element ratios (B/Nb, Ba/Nb, Pb/Nb, and K/Nb) are used to examine slab-derived com- ponent to mantle source. -
Processes of Policy Mobility in the Governance of Volcanic Risk
1 Processes of Policy Mobility in the Governance of Volcanic Risk Graeme Alexander William Sinclair Lancaster Environment Centre Lancaster University Lancaster LA1 4YQ UK Submitted 2019 This thesis is submitted for the degree of Doctor of Philosophy. 2 Statement of Declaration I hereby declare that the content of this PhD thesis is my own work except where otherwise specified by reference or acknowledgement, and has not been previously submitted for any other degree or qualification. Graeme A.W. Sinclair 3 Abstract —National and regional governments are responsible for the development of public policy for volcanic risk reduction (VRR) within their territories. However, practices vary significantly between jurisdictions. A priority of the international volcanological community is the identification and promotion of improved VRR through collaborative knowledge exchange. This project investigates the role of knowledge exchange in the development of VRR. The theories and methods of policy mobility studies are used to identify and explore how, why, where and with what effects international exchanges of knowledge have shaped this area of public policy. Analyses have been performed through the construction of narrative histories. This project details the development of social apparatus for VRR worldwide, depicted as a global policy field on three levels - the global (macro) level; the national (meso) level; and at individual volcanoes (the micro level). The narratives track the transition from a historical absence of VRR policy through the global proliferation of a reactive 'emergency management' approach, to the emergence of an alternative based on long-term planning and community empowerment that has circulated at the macro level, but struggled to translate into practice. -

Dressing the Leader, Dressing the Ancestor: The longue durée in the South Central Andes Ann H. Peters The preservation and adornment of the dead in the South Central Andes can be traced over some twelve thousand years. The nature of social and political ancestry and its relationship to power change over time with the development of large-scale complex societies. These changes are reflected in the types of garments used to dress the outside of mortuary bundles and their references to socio-political roles and associations. Archaeology has barely begun to develop the analytic approaches to take advantage of textile analysis in order to reconstruct – or theorize – multifaceted identities, networks of social and political relationships, and production and exchange practices embedded in particular environments. -

Indirect Tephra Volume Estimations Using Theorical Models for Some Chilean Historical Volcanic Eruptions with Sustained Columns J.E

II, Buenos Aires, Argentina. * Presenting Author’s email: [email protected] Introduction During explosive volcanic eruptions, diverse pyroclastic products are discharged from an eruptive column. Those columns are divided into three zones; 1) a basal gas thrust one, 2) medial convective and 3) a top umbrella region (Sparks, 1986) as is indicated in figure 1a. In this last one, where the column is dispersed laterally and radially forming a dispersion cloud or volcanic plume, the column reaches an Ht region due its momentum (Fig.1a). There has been defined two types of eruptive columns in relation with the time between single explosions. If the time between explosions exceeds the time of ascension of a column until its Ht height, the column is thermal, and in the opposite case, if the ascension time is smaller than the separation between explosions, this column is sustained (Sparks, 1986; Carey and Bursik, 2000). A good agreement has been found in the prediction of column heights and field observations for the case of columns which extends higher than the tropopause (Settle, 1978; Wilson et al, 1978; Sparks and Wilson, 1982; Sparks, 1986). -
