On the Link Between Global Volcanic Activity and Global Mean Sea Level

Studying a large number of volcanic eruptions is way to decipher general characteristics related volcano dynamics but also on external forcing influencing it, such as solid Earth and ocean tides. Many studies have tackled this tidal influence the onset more generally, activity. However, interplay between quasi-permanent systems still poorly understood. With present study, we propose consider global viewpoint address interaction. We analyzed monthly mean sea level 1880 2009 using Singular Spectrum Analysis time-series analysis technique evaluate existence common periodicities. found multi-decadal components similar periodicities in both which link those already recognized polar motion. Its variations result mass reorganization oceans whose associated stress changes may impact processes generating worldwide. Our results show activity open many questions further investigate these multi-scale interactions.
