Volcanic eruption of Nishinoshima Island in the Ogasawara Islands was confirmed in November 2013 and thereafter the area of the island carried on expanding. The Geospatial Information Authority of Japan (GSI) has repeatedly conducted aerial photography to grasp the situation of the expanding island as a part of the national land management. GSI created and updated maps of the island and published them in June 2017, using aerial photos which were taken by GSI while volcanic activities of the island once ceased. This report introduces the GSI's operations such as taking aerial photos and creating new maps of the island during its activities.
