Estimation of the surface deformation of the slopes of the Turrialba volcano (Costa Rica) after an eruption using Sentinel-1A differential synthetic aperture radar interferometry (SAR)

Differential synthetic aperture radar interferometry (SAR) is a technique known in remote sensing for its applications in the generation of digital terrain models and the monitoring of deformations of the earth’s crust. This technique is based on the phase, a parameter present in SAR images and sens...

This technique is based on the phase, a parameter present in SAR images and sensitive to terrain topography. Phase differences are related to elevation changes that occur between two satellite scans over the same space. To obtain topographic information, a digital terrain model is required and thus, phase differences provide information for estimating vertical terrain displacement to an accuracy greater than 1 centimeter. In the present work it was possible to estimate the surface deformation that occurred on the western slope of the crater of the Turrialba volcano after the eruption of August 1, 2020. For this purpose, several images captured by the Sentinel-1A sensor of the European Space Agency were used.La interferometría diferencial con radar de apertura sintética (SAR) es una técnica conocida en teledetección por sus aplicaciones en la generación de modelos digitales del terreno y el monitoreo de deformaciones de la corteza terrestre. Esta técnica se basa en la fase, un parámetro presente en las imágenes SAR y sensible a la topografía del terreno. Las diferencias de fase se relacionan con cambios de elevación ocurridos entre dos barridos del satélite sobre un mismo espacio. Para la obtención de información topográfica se requiere un modelo digital del terreno y la diferencia de fase permite realizar estimaciones de desplazamiento vertical del terreno con precisiones superiores a 1 centímetro. El presente trabajo permitió estimar la deformación superficial experimentada en la ladera oeste del cráter del volcán Turrialba tras la erupción del 1 de agosto de 2020. Para ello se utilizaron varias imágenes captadas por el sensor Sentinel 1A, de la Agencia Espacial Europea.Universidad Nacional, Costa Rica2021-10-29info:eu-repo/semantics/publishedVersionEvaluado por paresartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdftext/htmlapplication/epub+zipaudio/mpeghttps://www.revistas.una.ac.cr/index.php/geografica/article/view/1501310.15359/rgac.68-1.3Revista Geográfica de América Central.; Vol. 1 No. 68 (2022): Revista Geográfica de América Central; 79 - 101Revista Geográfica de América Central.; Vol. 1 Núm. 68 (2022): Revista Geográfica de América Central; 79 - 101Revista Geográfica da América Central; v. 1 n. 68 (2022): Revista Geográfica de América Central; 79 - 1012215-25631011-484Xreponame:Portal de Revistas UNAinstname:Universidad Nacional de Costa Ricainstacron:UNAspahttps://www.revistas.una.ac.cr/index.php/geografica/article/view/15013/23487https://www.revistas.una.ac.cr/index.php/geografica/article/view/15013/23488https://www.revistas.una.ac.cr/index.php/geografica/article/view/15013/23489https://www.revistas.una.ac.cr/index.php/geografica/article/view/15013/23490Derechos de autor 2021 Rubén Martínez-Barbáchanoacceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2022-02-21T14:33:18Zoai:www.revistas.una.ac.cr:article/15013Portal de revistashttp://revistas.una.ac.cr/Universidadhttp://www.una.ac.crhttps://revistas.una.ac.cr/index.php/index/oaiandrea.mora.campos@una.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:2022-02-21T14:33:18Portal de Revistas UNA - Universidad Nacional de Costa Ricafalse
