In this study, the geomagnetic variations related to the eruptions of Sakurajima on August 18, 2013 will be the focus of analysis. The data used for the analysis were collected CYG, KAK, KNY, and MMB observatories. This study carried out two methods. Firstly, we applied plot in a row that geomagnetic data in order to compare each component.<\/jats:p>\n                  <jats:p>Secondly, wavelet-based semblance analysis have analyzed geomagnetic data from different observatories.
