Public support for wood smoke mitigation policies in south-central Chile

Air Quality, Atmosphere & Health, 2018
This study analyzes the role of the affect heuristic, risk perceptions, and air quality and sociodemographic factors in the support for policies to control urban air pollution. The sample includes 489 participants residing in Temuco and Padre Las Casas, suburban areas located in southern Chile, affected by the smoke that wood-burning stoves and cookers

Massive Sulfides in the Greenstone Belt of South-Central Chile

1990
The investigations done by the Instituto de Investigaciones Geologicas (former Geological Survey of Chile) and the Department of Geosciences of the University of Concepcion during the last 10 years have shown that in the Coastal Range of south-central Chile, between 38° and 42° south latitude, there are ore occurrences related with a structurally ...

A vulnerability analysis of the temperate forests of south central Chile

Biological Conservation, 2005
Areas of the landscape that are priorities for conservation should be those that are both vulnerable to threatening processes and that if lost or degraded, will result in conservation targets being compromised. While much attention is directed towards understanding the patterns of biodiversity, much less is given to determining the areas of the ...

Holocene coseismic and aseismic uplift of Isla Mocha, south-central Chile

Quaternary International, 1992
Abstract During the past 6000 years Isla Mocha, a 12 km-long island 30 km off the coast of south-central Chile, experienced a 38 m fall of relative sea level caused primarily by rapid tectonic uplift of the island. As many as 18 raised shorelines (strandlines) record this uplift.

Monte Verde, South‐Central Chile: Stratigraphy, climate change, and human settlement

Geoarchaeology, 1988
AbstractTwo sedimentary units are recognized by means of stratigraphic and sedimentological analyses at Monte Verde, a late Pleistocene archeological site with stone tools and well‐preserved wood artifacts and botanical remains, that lies southwest of Lago Llanquihue and north of the Golfo de Reloncavi in the southern end of the Chilean Central graben.

Dynamic equifinality: The case of south-central Chile’s evolving forest landscape

Applied Geography, 2011
Abstract This paper explores a modified conceptual model of equifinality and applies it to an evolving landscape in south-central Chile. The equifinality model assumes that for a given open system, phenomena can take different paths and reach the same end state.

Net Late Holocene emergence despite earthquake-induced submergence, south-central Chile

Quaternary International, 1992
Abstract Intertidal deposits show net Late Holocene emergence at three sites along the Pacific coast near Maullin and Carelmapu, Chile (latitude 41.6–41.7°S.). The maximum amount of net emergence is ca. 1 m in the past 1500 years and ca. 2 1 2 m in the past 4000 years. Emergence probably would have prevailed at a fourth site near Maullin were

Polycyclic aromatic hydrocarbons in sediments and mussels of Corral Bay, south central Chile

Journal of Environmental Monitoring, 2004
PAHs were measured in sediments and mussels (Mytilus chilensis) from Carboneros and Puerto Claro, located in Corral Bay, Valdivia. According to the ratio of phenanthrene/anthracene and fluoranthene/pyrene concentrations, these sites are medium polluted with PAHs originating mainly from pyrolytic sources. Fluoranthene was the major component measured in

Coastal lake records of past tsunamis in South-Central Chile

Overlying the subducting Nazca Plate, Chile’s coastline is notoriously prone to megathrust earthquakes and associated tsunamis, as illustrated by the 2010 Maule (Mw 8.8) and 1960 Valdivia (Mw 9.5) events. Despite numerous geophysical and paleoseismic studies, many questions remain about the timing, location and rupture extent of great ...

Characterization of Red-clay soils of the South-Central Chile

1995
Numerous studies have demonstrated the importance of soil characteristics in the development of forest plantations. The objective of this study was to determine the variability in the morphological and physical properties of red-clay soils of the Collipulli series (an Andisol), as well as its limiting factors and fertility in various topographic ...
