Analysis of the volcanic evolution of Nevado del Ruiz from the last eruptive period to the current state, using multispectral images provided by the group of satellites SENTINEL 1-2-3

The analysis of satellite images produced by remote sensors, are a great tool for the identification of a range of ground cover and topsoil to the identification of particular lithologies and rock configurations regionally. The main objective is to evaluate the ability of Landsat and Sentinel satell...

description The analysis of satellite images produced by remote sensors, are a great tool for the identification of a range of ground cover and topsoil to the identification of particular lithologies and rock configurations regionally. The main objective is to evaluate the ability of Landsat and Sentinel satellites to define lithologies and types of volcanic flow and with them to carry out a hazard analysis. The particular features that are going to be analyzed correspond to: lava flows, lahars, ash, volcanic gases, volcanic rocks, erosion, snow, vegetation cover as well as other features such as slopes and water sources of the Nevado del Ruiz volcano. The information has been collected through an analysis that includes a multitemporal period from the last eruptive period to the present. In addition, images of past years to this last eruptive period were analyzed, where the peaks with the highest volcanic activity were recorded, in order to complement the results obtained. The justification for the acquisition of these results lies in creating volcanic geology mapping of ash, lava flows, pyroclasts, snow and lahars flows that clearly demonstrate the dangers that the volcano represents to nearby populations and avoid tragedies such as the one that happened in the municipality of Armero in the year of 1985.

El objetivo principal es evaluar la capacidad de los satélites Landsat y Sentinel para definir litologías y tipos de flujo volcánico y con ellos realizar un análisis de peligros. Las características particulares que se analizarán corresponden a: flujos de lava, lahares, cenizas, gases volcánicos, rocas volcánicas, erosión, nieve, cubierta vegetal, así como otras características como pendientes y fuentes de agua del volcán Nevado del Ruiz. La información se ha recopilado mediante un análisis que incluye un período multitemporal desde el último período eruptivo hasta el presente. Además, se analizaron imágenes de años anteriores a este último período eruptivo, donde se registraron los picos con la mayor actividad volcánica, para complementar los resultados obtenidos. La justificación para la adquisición de estos resultados radica en crear mapas geológicos volcánicos de flujos de cenizas, flujos de lava, piroclastos, nieve y lahares que demuestren claramente los peligros que representa el volcán para las poblaciones cercanas y evitar tragedias como la que ocurrió en el municipio de Armero en el año de 1985.GeocientíficoPregrado48 hojasapplication/pdfengUniversidad de los AndesGeocienciasFacultad de CienciasDepartamento de Geocienciasinstname:Universidad de los Andesreponame:Repositorio Institucional SénecaAnalysis of the volcanic evolution of Nevado del Ruiz from the last eruptive period to the current state, using multispectral images provided by the group of satellites SENTINEL 1-2-3Trabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesishttp://purl.org/coar/resource_type/c_7a1fhttp://purl.org/coar/version/c_970fb48d4fbd8a85Texthttp://purl.org/redcol/resource_type/TPVolcán Nevado del Ruiz (Colombia)Satélites científicosSatélites LandsatTecnología de satélites en recursos de la tierraErosión de suelosGeocienciasPublicationORIGINALu830866.pdfapplication/pdf4620897https://repositorio.uniandes.edu.co/bitstreams/ad957ca5-257f-4f97-8c8a-865434fcaf4c/download3b6e66d081c87aa8b2ee38260c76d712MD51TEXTu830866.pdf.txtu830866.pdf.txtExtracted texttext/plain82548https://repositorio.uniandes.edu.co/bitstreams/77cd4170-c5c2-423c-86dd-db8d1a2c9c04/download40445be15f847b5e50a2d8b419cb014eMD54THUMBNAILu830866.pdf.jpgu830866.pdf.jpgIM Thumbnailimage/jpeg10590https://repositorio.uniandes.edu.co/bitstreams/2e503c92-36ee-40db-aa9f-3efa6c9089b4/downloade1ac8bd881b272a7eaffb399c3d1df13MD551992/44697oai:repositorio.uniandes.edu.co:1992/446972023-10-10 19:36:01.442http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co
