Resumen
[ES] Los incendios forman parte de la dinámica de los ecosistemas europeos, y al mismo tiempo representan un verdadero desastre ecológico (Jaiswal et al. 2002), particularmente a la isla de Gran Canaria en los últimos años. En este trabajo se analiza los incendios forestales ocurridos el 17 de agosto de 2019, que arrasaron 9.636,40 hectáreas (según datos oficiales), para ello se ha usado Google Earth Engine (GEE) y las imágenes Sentinel-2, con el propósito de evaluar la zona afectada por el fuego (severidad), la pérdida de cobertura vegetal y detectar su recuperación. Los resultados obtenidos muestran una superficie total quemada de 85.3 km2, con una severidad moderada baja de 25.42 km2. Se afectaron 9 municipios, 6 áreas protegidos y los bosques de coníferas y la vegetación esclerófilas fueron las más afectadas y finalmente para el año 2021 hubo una alta recuperación.
