This eruptive process gave the opportunity to analyze the possible existence of any relation between earthquakes and tide for each of the stages of the process. In order to verify that, several earthquakes swarms were selected from each stage. Subsequently, each swarm was subjected to different spectral analysis techniques. The results obtained in this work, demonstrated the existence of a strong influence of the tide with earthquakes, especially in the pre-eruptive stage and the reactivation swarm of the posteruptive stage. It is also noteworthy, that the influence of the semi-diurnal tide respect to the probability of occurrence of earthquakes is more significant than the diurnal tide. Moreover, this study also demonstrated the existence of higher occurrence of earthquakes during events of low tide with respect to high tide.||Department:||Departamento de Química||Faculty:||Facultad de Ciencias del Mar||Degree:||Grado en Ciencias del Mar||URI:||http://hdl.handle.net/10553/74932|
