Abstract:	Eruptive activity at Showa crater of Sakurajima volcano resumed in June 2006 after 58 years dormancy of the crater. (Iguchi et al., 2009) Monitoring Sakurajima volcano is particularly important because of its location in a densely populated. Because Global Position System (GPS) is a very important tool to detect magma supply within the order of cm or less, GPS continuous monitoring system at center of north Sakurajima and Aira Caldera was started from 1995 by Kyoto University Disaster Prevention Research Institute Sakurajima Volcano Research Center. (Iguchi et al., 2008) Since 2005, the system has been upgraded with new generation GPS receiver and new positioning software. In this paper, we will discuss features of upgraded Sakurajima GNSS network monitoring system. From temporal and spatial distribution of horizontal displacements which were estimated by GPS network observation since Oct. 2009 for one year, performance of the system can be proved.
