 note = {Structural state of plagioclases within volcanic ash erupted from Sakurajima volcano was preliminarily investigated for monitoring the volcanic activity. Samples were collected for about one and a half years from May 2013 at Higashi-Sakurajima Junior High School and for 8 months from May 2015 at the Faculty of Education, Kagoshima University, which are located about 4 km southwest and 11 km west of Minami-dake crater of Sakurajima volcano respectively. X-ray powder diffraction data for the plagioclase suggests gradual change in degree of order in the crystal structure during this period.},
