The comparison of the images revealed the presence\u3000of increased material across the activated Minamidake and beneath the deactivated Showa crater.\u3000Muography detected the formation of a magma plug in the conduit of Showa crater that was not detected\u3000earlier by any other geophysical technique. These results demonstrate the applicability of cosmic muon\u3000imaging for monitoring of magma movements inside active volcanoes.<\/p>\n<p><a href=\"http:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2019\/10\/sakurajima-2.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-2685\" src=\"http:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2019\/10\/sakurajima-2-300x107.jpg\" alt=\"\" width=\"300\" height=\"107\" srcset=\"https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2019\/10\/sakurajima-2-300x107.jpg 300w, https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2019\/10\/sakurajima-2-768x275.jpg 768w, https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2019\/10\/sakurajima-2-1024x367.jpg 1024w, https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2019\/10\/sakurajima-2-1200x430.jpg 1200w, https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2019\/10\/sakurajima-2-500x179.jpg 500w\" sizes=\"(max-width: 300px) 85vw, 300px\" \/><\/a><a href=\"http:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2019\/10\/GRL_CoverImage_201909-2.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-medium wp-image-2689\" src=\"http:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2019\/10\/GRL_CoverImage_201909-2-227x300.png\" alt=\"\" width=\"227\" height=\"300\" srcset=\"https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2019\/10\/GRL_CoverImage_201909-2-227x300.png 227w, https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2019\/10\/GRL_CoverImage_201909-2-379x500.png 379w, https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2019\/10\/GRL_CoverImage_201909-2.png 743w\" sizes=\"(max-width: 227px) 85vw, 227px\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>L\u00e1szl\u00f3 Ol\u00e1h1\u30fbHiroyuki K.M.
