Las morfologías blowout han sido descritas por diversos autores como formas naturales e intrínsecas a los sistemas de dunas litorales, que se definen como plataformas erosivas dentro de la dinámica sedimentaria eólica. Los estudios existentes hasta el momento se han centrado en su caracterización física y dinámica desde una perspectiva limitada a cada ámbito en donde se han llevado a cabo dichos estudios. No existen, en este sentido, estudios comparados de dichas morfologías, a pesar de que los blowouts se localizan en la mayor parte de los sistemas de dunas a escala planetaria. El presente trabajo tiene como objetivo principal establecer una aproximación comparativa entre distintos blowouts presentes en ambientes geográficos notablemente diferentes, y bajo distintas condiciones de génesis y dinámica: el sistema de Cala Mesquida (Mallorca), un blowout interior en el campo de dunas de Maspalomas (Gran Canaria), y varios blowouts interiores del sistema intermareal de Carnota (Galicia). La divergencia entre las características físicas de los sistemas analizados sugiere la existencia de algunas diferencias en tanto a las morfologías estudiadas, lo cual se relaciona con su génesis y evolución
Blowout morphologies have been described by several authors as natural and intrinsic shapes to coastal dune systems, and defined as erosive platforms within the aeolian and sedimentary dynamic. The studies existing so far have focused on their physical and dynamic characterization, however only considering the features of the places where those works have been carried out. In this sense there not exist any work dealing about the comparison of these morphologies, although blowouts are recurrent on dune systems over the world. In this sense, the present work aims to establish an initial comparative approach between blowouts existing on different geographical places, under divergent conditions of genesis and dynamics: the dune complex of Cala Mesquida (Mallorca), an internal blowout of the system of Maspalomas (island of Gran Canaria), and finally several internal blowouts existing on the intertidal system of Carnota (Galícia). The divergence existing among the analyzed systems suggests the presence of some differences between the studied morphologies, which is related with their genesis and evolution.
