Detail of larger tracks shown in photograph 7. Individual tracks are 90 centimeters in diameter. Mud ridges are 10 to 15 centimeters above dipslope rock. Man for scale. Tarapaca Province, Chile. 1955. Published in U.S. Geological Survey Bulletin 1189, Figure 8-A. 1965.
This maps portrays the spatial potential for damaging earthquake ground shaking quantified as considerable (MMI ≥ VIII) in 100 years. The maps and data are based on the average of the results obtained from peak ground acceleration and 1.0-second horizontal spectral acceleration. Site specific soil factors based on Vs30 shear wave velocities were implemented using a simple topographic proxy technique (Allen and Wald, 2009) and site amplification based on the relationships of Seyhan and Stewart (2014). MMI ≥ VIII is equivalent to peak ground acceleration of 0.40g and 1.0-second horizontal spectral acceleration of 0.50g (Worden et al., 2012). Allen, T.A. and Wald, D.J. 2009,. On the use of high-resolution topographic...

This maps portrays the spatial potential for damaging earthquake ground shaking quantified as slight (MMI ≥ VI) in 100 years. The maps and data are based on the average of the results obtained from peak ground acceleration and 1.0-second horizontal spectral acceleration. Site specific soil factors based on Vs30 shear wave velocities were implemented using a simple topographic proxy technique (Allen and Wald, 2009) and site amplification based on the relationships of Seyhan and Stewart (2014). MMI ≥ VI is equivalent to peak ground acceleration of 0.12g and 1.0-second horizontal spectral acceleration of 0.1g (Worden et al., 2012). Allen, T.A. and Wald, D.J. 2009,.

A seismic hazard model for South America, based on a smoothed (gridded) seismicity model, a subduction model, a crustal fault model, and a ground motion model, has been produced by the U.S. Geological Survey. These models are combined to account for ground shaking from earthquakes on known faults as well as earthquakes on un-modeled faults. This data set represents the results of calculations of hazard curves for a grid of points with a spacing of 0.1 degrees in latitude and longitude. This particular data set is for Modified Mercalli Intensity with a 10 percent probability of exceedance in 50 years. The maps and data were derived from PGA ground-motion conversions of Worden et al. (2012), and include soil amplification...

Chile and Peru produce almost 45% of world's mine copper output. This situation reflects their natural endowment and mining tradition, but is also the result of development processes undertaken over the last decades. As a result, both countries multiplied its mine copper production in more than 3 times in the last 20 years. Mining labor productivity played a central role achieving these amazing growth rates. Although there is a consensus about the relevance of this variable for the mining industry, the specific factors behind labor productivity changes are not completely understood. In this paper we use a panel data approach to analyze labor productivity in the copper mining sector in Chile and Peru from 1992 to...

Most populations of migrant shorebirds around the world are in serious decline, suggesting that vital condition-dependent rates such as fecundity and annual survival are being affected globally. A striking example is the red knot (Calidris canutus rufa) population wintering in Tierra del Fuego, which undertakes marathon 30,000 km hemispheric migrations annually. In spring, migrant birds forage voraciously on horseshoe crab eggs in Delaware Bay in the eastern USA before departing to breed in Arctic polar deserts. From 1997 to 2002 an increasing proportion of knots failed to reach threshold departure masses of 180-200 g, possibly because of later arrival in the Bay and food shortage from concurrent over-harvesting...

Salt stalactites on overturned slab of rock salt, formed by solution of salt by rainwater and fog, eastern side of Salar de Atacama (pen gives scale). Antofagasta Province, Chile. Circa 1962. Published in U.S. Geological Survey Professional Paper 811, Figure 40-D. 1974.
This dataset presents information about mineral commodity exporting ports relating to the mineral industries of Latin America and the Caribbean. Port data records were originally derived from the National Geospatial-Intelligence Agency's World Port Index, with additional research conducted by the Material Flow Analysis section of the U.S. Geological Survey's (USGS) National Minerals Information Center (NMIC) to add specific mineral-related data. These ports represent known exporting ports over a time period of 2010-2016 and relevant data fields include the mineral commodities exported, the form of the exported mineral commodity, the port owner, the estimated annual tonnage, destination countries, as well as sources...
As a result of a Latin American Coal Assessment, the USGS published the first Coal Map of South America (Weaver and Wood, 1994) and developed a cooperative inter-American exchange of geologic information which lead to a better understanding of the potential for coal resource utilization in the western hemisphere. This coal study was started by the late Gordon H. Wood, Jr. The original compilation, completed before his death, was a result of library research and it did not include updated information from scientists and others in the coal-bearing countries of South America. During the Fall of 1991, Jean N. Weaver visited Uruguay, Argentina, Chile, Peru, Ecuador, Colombia, Venezuela, Brazil, and Bolivia. The purpose...
This data was used in the analysis for the article “Burn Severity Controls on Post-fire Araucaria-Nothofagus Regeneration in the Andean Cordillera” by T. Assal, M. Gonzalez and J. Sibold. The aim of the study was to investigate post-fire regeneration patterns of forests on the west slope of the Andes; to evaluate the relationship between remotely sensed burn severity and forest mortality; and to assess controls of burn severity on forest response at local spatio-temporal scales. This dataset reflects the burn severity calculated from Landsat data as part of the analysis.
Expected average annual losses from earthquakes are determined by using PAGER's vulnerability functions that are unique to each country. There are significant differences in economic losses between countries, which is indicative of their relative vulnerability to earthquakes.

Clasificación de Pisos de Vegetación para Chile continental presentada en el libro "Sinopsis Bioclimatica y Vegetacional de Chile" de Federico Luebert y Patricio Pliscoff, Editorial Universitaria, 2006. El concepto de piso de vegetación es defindo aquí como "espacios caracterizados por un conjunto de comunidades vegetales zonales con estructura y fisionomía uniforme, situadas bajo condiciones mesoclimáticamente homogéneas, que ocupan una posición determinada a lo largo de un gradiente de elevación, a una escala espacio-temporal específica". Sintetiza la respuesta de la vegetación, en términos de su fisionomía y especies dominantes, a la influencia del mesoclima, reflejado a través de la definición de pisos bioclimáticos....
