Publicación Acceso abierto Caracterización geomorfológica del sistema volcánico sedimentario en la zona noreste de La Lorenza-Córdoba(2021-09-22) Pernett Suarez, Daniel; Villegas Sánchez, Maira; Mejía Ávila, DorisThis study allowed the characterization of the major exponents of sedimentary volcanism in Canalete; San Diego mud volcano and El Palmar mud volcano, through the interpretation of UAV photographs and satellite images and field reconnaissance, based on the geomorphological hierarchy of these two volcanoes, we found among the main components, mud deposits, faucets, salsa lakes in the sedimentary volcanic environment (vl) and components such as minor erosion escarpment, minor erosion scarp and minor erosion scarp, salsa lakes in the Sedimentary Volcanic environment (vl) and components such as minor erosion scarp, fault scarp and solifluxion lobes in the Denudational Structural environment (Sd), it was defined in these volcanoes according to the classification of Mazzini and Ethiopian (2017), the form of plateau for San Diego and dome for Palmar. Similarly, based on the analysis of the dynamics of these components, it was defined that the greatest threat from volcanism is related to the expulsion of consolidated material, mud flows and the erosive processes they bring, which generate a greater threat to the inhabitants of the Casa Tabla farm, which are located at a distance of at least 400 meters from the San Diego volcano, for the case of Palmar, the threat is directed to the road structure that is only meters away from the volcano.Publicación Acceso abierto Caracterización geomorfológica e identificación de las geo amenazas por volcanismo sedimentario en el sector occidental del volcán San Diego, Canalete, Colombia(2021-09-28) Barros de la Espriella, María Carolina; Martínez Lara, Zoraya Yasquine; Mejía Ávila, DorisIn the municipality of Canalete - Córdoba, in the village of La Lorenza, there is an important sedimentary volcanic system made up of volcanoes such as Palmar and San Diego, the western sector of the San Diego volcano being considered as the study area in the present investigation, the main objective of the study was to characterize the geomorphological features of the sector in order to provide information that favors the identification of threats due to sedimentary volcanism, this objective was achieved through the interpretation and analysis of UAV photographs by means of GIS in conjunction with field control. ; This project was worked on at a scale of 1: 500, managing to detail as many geoforms as possible in the studied area, within which taps, sauces, pools and multicrater leaks were found that could be correlated with different types of threat, thus allowing to determine that the San Diego mud volcano area studied is associated with mud gap and flow ejection threats and fires.
