Metodología: Se parte de la división de la superficie de estos dos municipios en polígonos de 600 metros. De esta forma, a través de la información de actividad de rayos (impactos nube-tierra) proporcionada por la Red Colombiana de Detección Total de Rayos - LINET entre enero de 2016 y febrero de 2020, se determinó el número de impactos por polígono, lo que permitió identificar los hotspots en las zonas de estudio Así mismo, se identificaron y localizaron estructuras elevadas como torres de transmisión, antenas de telecomunicaciones y edificaciones, y se estableció para cada una de ellas un radio de influencia de 300 m, teniendo en cuenta el error medio de localización de la Red LINET, de esta manera se determinaron las 20 estructuras con mayor número de impactos de rayo.  Resultados: Se encontraron los polígonos con mayor actividad de rayos, de los cuales 34 se ubican en Barrancabermeja y 235 en Yondó, lo que concuerda con mapas de densidad de descargas a tierra hechos en la zona en donde se presenta un aumento en la cantidad de descargas por kilómetro cuadrado por año en Yondó, en comparación con Barrancabermeja. Se localizaron 616 estructuras elevadas en los municipios de Barrancabermeja y Yondó de las cuales se escogieron las 20 con mayor cantidad de impactos de rayo que corresponden en un 50 % a torres de transmisión, siendo la estructura de mayor número de impactos una torre de transmisión de 70 m de altura localizada en límites de los dos municipios de estudio con un total de 68 impactos.  Conclusiones: De las 27 estructuras elevadas encontradas en Yondó, solo 6 se ubican en algún hotspot, lo que muestra que en este municipio la presencia de alguna estructura elevada no garantiza un hotspot y que los sitios de mayor actividad de rayos no se ven influenciados por la presencia de estructuras elevadas. Ahora bien, para el caso de Barrancabermeja se hallaron 10 estructuras elevadas en un hotspot, de las cuales 7 están en el casco urbano donde se encontraron 9 hotspots, de donde se infiere que, en este municipio, el urbanismo y la presencia de estructuras elevadas si aumentan la actividad de rayos.

<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract  Objective: This paper presents a methodology to determine the zones and elevated structures with the highest number of lightning strikes (Hotspots) in Barrancabermeja and Yondó.  Methodology: It starts from the division of the surface of these two municipalities into polygons of 600 meters. In this way, using the information of lightning activity (cloud-ground impacts) provided by the Colombian Network for Total Lightning Detection LINET between January 2016 and February 2020, the number of impacts per polygon was determined, which made it possible to identify the hotspots in the study areas. Likewise, elevated structures such as transmission towers, telecommunications antennas and buildings were identified and located and a radius of influence of 300 meters was established for each one of them taking into account the mean error of location of the LINET network. In this way it was possible to determine the twenty structures with the highest number of lightning strikes.  Results: The polygones with the highest lightning activity were found, of which 34 are located in Barrancabermeja and 235 in Yondó, which is consistent with maps of Density of Discharges to land made in the area where there is an increase in the number of flashes per square kilometer per year in Yondó compared to Barrancabermeja. 616 elevated structures were located in the municipalities of Barrancabermeja and Yondó, of which the twenty with the highest number of lightning strikes were chosen, which correspond 50% to transmission towers, the structure with the highest number of impacts being a transmission tower of 70 meters high located on the border of the two study municipalities with a total of 68 impacts.  Conclusions: Of the 27 elevated structures found in Yondó, only 6 are located in a hotspot, which shows that in this municipality the presence of an elevated structure does not guarantee a hotspot and that the sites with the highest lightning activity are not influenced by the presence of elevated structures. Now, in the case of Barrancabermeja, 10 elevated structures were found in one of the hotspots, of which 7 are located in the urban area where 9 hotspots were found, from which it is inferred that in this municipality the urban planning and the presence of elevated structures, indeed increases the lightning activity.
