This book was released on 2015-04-09 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Special Publication arises from the UNESCO-sponsored IGCP 586-Y project `The tectonics and geomorphology of the Andes (32°–34°S): interplay between short-term and long-term processes’. It includes state-of-the-art reviews and original articles from a multidisciplinary perspective that investigate the complex interactions of tectonics and surface processes in the subduction-related orogen of the Andes of central Chile and Argentina (c. 27° –39°S). It aims to improve our understanding of tectonic and landscape evolution of the Andean range at different time scales, as well as the mutual relationship between internal and external mechanisms in Cenozoic deformation, mountain building, topographic evolution, basin development and mega-landslides occurrence across the flat slab to normal subduction segments. The geodynamic processes of the Andes of central Chile and Argentina are analysed from a number of subdisciplines of the Earth sciences, including tectonics, petrology, geophysics, geochemistry, structural geology, geomorphology, engineering geology, stratigraphy and sedimentology.

Book Synopsis Remote Sensing of Volcanic Processes and Risk by : Francesca Cigna
Download or read book Remote Sensing of Volcanic Processes and Risk written by Francesca Cigna and published by MDPI. This book was released on 2021-03-17 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remote sensing data and methods are increasingly being implemented in assessments of volcanic processes and risk. This happens thanks to their capability to provide a spectrum of observation and measurement opportunities to accurately sense the dynamics, magnitude, frequency, and impacts of volcanic activity. This book includes research papers on the use of satellite, aerial, and ground-based remote sensing to detect thermal features and anomalies, investigate lava and pyroclastic flows, predict the flow path of lahars, measure gas emissions and plumes, and estimate ground deformation. The multi-disciplinary character of the approaches employed for volcano monitoring and the combination of a variety of sensor types, platforms, and methods that come out from the papers testify to the current scientific and technology trends toward multi-data and multi-sensor monitoring solutions. The added value of the papers lies in the demonstration of how remote sensing can improve our knowledge of volcanoes that pose a threat to local communities; back-analysis and critical revision of recent volcanic eruptions and unrest periods; and improvement of modeling and prediction methods. Therefore, the selected case studies also demonstrate the societal impact that this scientific discipline can potentially have on volcanic hazard and risk management.
Book Synopsis Remote Sensing Applications to Earth Surface Processes in the Eastern Central Andes by : Benjamin Purinton
Download or read book Remote Sensing Applications to Earth Surface Processes in the Eastern Central Andes written by Benjamin Purinton and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geomorphology seeks to characterize the forms, rates, and magnitudes of sediment and water transport that sculpt landscapes. This is generally referred to as earth surface processes, which incorporates the influence of biologic (e.g., vegetation), climatic (e.g., rainfall), and tectonic (e.g., mountain uplift) factors in dictating the transport of water and eroded material. In mountains, high relief and steep slopes combine with strong gradients in rainfall and vegetation to create dynamic expressions of earth surface processes. This same rugged topography presents challenges in data collection and process measurement, where traditional techniques involving detailed observations or physical sampling are difficult to apply at the scale of entire catchments. Herein lies the utility of remote sensing. Remote sensing is defined as any measurement that does not disturb the natural environment, typically via acquisition of images in the visible- to radio-wavelength range of the electromagnetic spectrum. Remote sensing is an especially ...

Book Synopsis Quaternary Landscape Evolution of the Southern Central Andes of Chile Quantified Using Landslide Inventories, Be and C1 Cosmogenic Isotopes and (U-Th)/He Thermochronology by : José Luis Antinao Rojas
Download or read book Quaternary Landscape Evolution of the Southern Central Andes of Chile Quantified Using Landslide Inventories, Be and C1 Cosmogenic Isotopes and (U-Th)/He Thermochronology written by José Luis Antinao Rojas and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Andes Mountains--the largest subduction orogen in the world--are a unique natural laboratory suited to test interactions at different timescales between tectonic and surface processes. However, Andean Landscape Evolution still remains relatively understudied. This lack of knowledge will probably change during the next few years with growing understanding of Andean rates and styles of geomorphic processes. Long term (10 (super 6) a) landscape evolution of the high relief Cordillera Principal, in the Chilean southern Central Andes (SCA), is strongly marked by the previous tectonic history of the orogen. Exhumation rates determined from apatite (U-Th)/He low-temperature thermochronology are on the order of approximately 1 mm a (super -1) since 2-3 Ma. The exhumation history is consistent with a segmented orogenic architecture in this region, with inherited pre-Cenozoic structures and domains that define not only the distribution of tectonic processes but also erosional styles in response to stress and deformation. Late Pliocene acceleration of exhumation from values of 0.3-0.4 mm a (super -1) has probably occurred along with surface uplift of Cordillera Principal, creating a high elevation area still present today that displays the highest Quaternary erosion rates in the SCA. Quaternary sediment production rates from landslide inventories on a long term (10 (super 6) a) basis (0.16 mm a (super -1) ) are similar to transport rates determined at intermediate timescales (0.25-0.5 mm a (super -1) over 10 (super 3) -10 (super 4) a) with the help of terrestrial cosmogenic nuclide (super 36) Cl inventories in stream sediment. The cosmogenic nuclide study confirmed that landslides dominate denudation providing a distinctive isotopic signature to the different grain sizes of the stream sediment. At short (10 a) timescales, total fluvial transport rates, including a modeled bedload component, are similar (0.25 mm a (super -1) ) to long- and intermediate-term production and transport rates. I conclude that during the Quaternary, occurrence of large landslides and increased activity of fluvial processes during glacial stages have removed efficiently mass from Cordillera Principal, in a waxing orogen. However, variability in erosion over long term timescales and the difference with inferred Quaternary exhumation indicates that a macroscale steady state has not been reached.

Book Synopsis GNSS-based Remote Sensing$binnovative Observation of Key Hydrological Parameters in the Central Andes by : Nikolaos Antonoglou
Download or read book GNSS-based Remote Sensing$binnovative Observation of Key Hydrological Parameters in the Central Andes written by Nikolaos Antonoglou and published by . This book was released on 2024* with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Central Andean region is characterized by diverse climate zones with sharp transitions between them. In this work, the area of interest is the South-Central Andes in northwestern Argentina that borders with Bolivia and Chile. The focus is the observation of soil moisture and water vapour with Global Navigation Satellite System (GNSS) remote-sensing methodologies. Because of the rapid temporal and spatial variations of water vapour and moisture circulations, monitoring this part of the hydrological cycle is crucial for understanding the mechanisms that control the local climate. Moreover, GNSS-based techniques have previously shown high potential and are appropriate for further investigation. This study includes both logistic-organization effort and data analysis. As for the prior, three GNSS ground stations were installed in remote locations in northwestern Argentina to acquire observations, where there was no availability of third-party data. The methodological development for the observation of the climate variables of soil ...

Download or read book Unraveling the Magmatic and Geomorphic Processes Recorded in the Topography of the Central Andes written by and published by . This book was released on 2015 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: The topography of volcanic arcs reflects a combination of magmatic ascent processes that deform the overlying crust, volcanic eruptions that blanket the surface in lava and ash, and geomorphic processes that shape these deposits into the observable landscape and consequently record an erosional archive of surface deformation. A central goal of geomorphology is to utilize the form of landscapes to infer the processes that shape them, yet comparatively little work has been done to quantitatively understand the geomorphology of volcanic landscapes. The Central Volcanic Zone of the South American Andes (CVZ, 15-28°S) represents an ideal location for understanding the processes that shape the surface of volcanic arcs; the arid climate and well-constrained geochronology of volcanic deposits provide a geomorphic archive going back 11 Myrs, and the wealth of available geophysical imaging data provides a high-resolution glimpse into the subsurface. In this thesis I utilize geormophic and geophysical data to explore fundamental questions in volcanic landscape evolution at varying spatial scales. To begin, I examine the isostatic uplift response to crustal intrusion of mantle-derived melt, resulting in growth of the largest known active magma reservoir on Earth (the Altiplano-Puna Magma Body). From topography I show that it is possible to calculate the contribution of mantle-derived melt to crustal thickening, and I compare these results to independent seismic estimates that agree well with our data. I then use the record of volcanic deposits from the Altiplano-Puna Magma Body to estimate the flux of mantle melt into the crust, and show that predicted uplift rates are comparable to the surface uplift associated with convective lithospheric removal. Next, I explore how the topography of individual volcanic systems can help discern the style of melt ascent from deeper crustal magma reservoirs to shallow ones. Using two actively deforming volcanoes in the CVZ, Uturuncu volcano and the Lazufre volcanic complex, I use river profiles, lake shorelines, and lava flow deflections to infer each volcano's surface deformation record into the geomorphic past. Uturuncu volcano shows little signs of permanent paleo-deformation, suggesting transient ascent of magma over millenial timescales, while Lazufre's long wavelength deformation suggests continued accumulation of magma since > 0.3 Ma. Finally, I utilize the unique topography of a windswept ignimbrite erupted from the Altiplano-Puna Magma body to better understand how wind abrasion can incise bedrock canyons, a fundamental geomorphic process in arid landscapes on both Earth and Mars. Using a natural experiment within the 4 Ma Puripicar ignimbrite on the western slope of the Central Andes, we quantify the relative contribution of wind and water erosion in propagating bedrock canyons and show that wind can incise canyons an order of magnitude faster than rivers, streamlining their profiles in the process. Thus, in these chapters I illustrate how geomorphology can be a useful tool for quantifying subsurface magmatic processes, while volcanic landscapes themselves can also provide unique opportunities for understanding fundamental planetary geomorphic processes not often observed elsewhere on Earth.
