Differential Interferometric Synthetic Aperture Radar technique has proven to be a reliable method for landslides monitoring and can be used for several purposed such as landslide hazard maps, urban planning and hazard mitigation strategies In this research we present the satellite monitoring of the Yerba Loca landslide occurred in august 2018 and...
La cuenca del estero Yerba Loca forma parte de la cuenca alta del río Mapocho y, por ende, parte de la gran cuenca del río Maipo, Chile central. En ella, se pueden observar los resultados de la historia geológica de los últimos 40 millones de años de la evolución andina, tanto del volcanismo y sedimentación como de la tectónica y alzamiento de la c...
Chile is one of the countries with the highest seismicity in the world and is affected by three types of seismogenic sources; interplate, intraplate and superficial or cortical intraplate. In this context, in the eastern sector of the city of Santiago, capital of Chile, the Falla San Ramón (FSR) is located. It is a cortical seismogenic source, whic...
Los ecosistemas andinos de Chile central son una de las zonas más vulnerables al cambio climático a nivel mundial. Además, estos ecosistemas históricamente han sido usados por las comunidades locales para realizar ganadería trashumante en verano (veranadas). Sin embargo, los impactos de las veranadas en los ecosistemas de montaña, en un contexto de...
Climate Change is affecting the precipitation patterns worldwide and especially in mountain areas and therefore changing the occurrence of rainfall-induced landslides. This chapter assesses the estimated effects and extension of landslides in Climate Change scenarios in the Andes of Central Chile, showing that despite the projected overall decrease...
Las áreas costeras de la región de Valparaíso de Chile por sus características oceanográficas, climáticas y ecológicasson de gran importancia para el desarrollo turístico, económico y ambiental del país. Las costas de la región se han vistoafectadas por eventos extremos desde 2015, con marejadas recurrentes que han aumentado respecto a años anterio...
In an era of increasing wildfires frequency and intensity an accurate estimation of the emissions released to the atmosphere is essential to reduce their impacts. In this study, we improve the accuracy of our estimations by introducing field measurements of biomass and adapting the burning efficiency factors to different levels of burn severity com...
Simple Summary
Measures of plant water status on kiwifruit were evaluated using Sentinel-2 (A/B) for two seasons in Central Chile.
Abstract
For more than ten years, Central Chile has faced drought conditions, which impact crop production and quality, increasing food security risk. Under this scenario, implementing management practices that allow i...
For more than ten years, Central Chile faces drought conditions, which impact crop production and quality, increasing food security risk. Under this scenario, implementing management practices that allow increasing water use efficiency is urgent. The study was carried out in kiwifruit trees, located in the O’Higgins region, Chile; for season 2018-2...
Seasonal changes control the development of salt crust over the Salar de Aguas Calientes Sur located in Andes Highlands, Chile. Precipitations throughout the Altiplanic winter (December to March) and austral winter (June to September) caused ponds to enlarge and surface salt crusts to dissolve driving roughness and dielectric features of the salar...
Since the year 2007, a megadrought has been affecting the water supply in Central Chile, reaching the year 2019 a critical condition. Currently, the information about how this drought is impacting vegetation productivity is scarce. This study aimed to analyze the vegetation productivity for season 2019-2020 by a remote sensing proxy which considere...
The objective of this work is to monitor the mining subsidence in a mountain range sector of central Chile between 2014 and 2018 through the processing of a time series of Sentinel 1 images using differential interferometry techniques (DInSAR). As a pretest, nine interferometric pairs were considered and processed using SNAP and SNAPHU software. Co...
The upper section of the Mapocho river basin is in constant danger of landslides. This study had the objective of zoning the upper Mapocho river basin for the susceptibility of landslides using hydrological, geological, and geomorphological data. Areas with a high degree of landslide susceptibility are located on the lower part of the main valleys...
p>The Araucaria araucana is an endemic species from Chile and Argentina, which has a high biological, scientific and cultural value and since 2016 has shown a severe affection of leaf damage in some individuals, causing in some cases their death. The purpose of this research was to detect, from hyperspectral images, the individuals of the Araucaria...
p>Wildfires destroy thousands of hectares of vegetation every year in Chile, a phenomenon that has steadily increased over time, both in terms of the number of fires and the area affected. Since 1985 until 2016 have occurred 1,476 wildfires severe in intensity (> 200 ha), that burned a total of about 1,243,407 ha of vegetation, and an average of 40...
