Sakurajima

Sakurajima is an active stratovolcano occupying a peninsula-formed island in Kagoshima Bay, off the coast of Kagoshima City in Kagoshima Prefecture, Japan. It is one of the country’s most active volcanoes, with near-constant low-level activity and occasional larger eruptions that send ash plumes and volcanic bombs into the surrounding area.

Geography and geology: The volcano began as an island in the bay. During the 1914 Taisho eruption, lava flows connected Sakurajima to the Osumi Peninsula, creating a land bridge and altering the coastline. The summit features a central crater complex with multiple vents and extrusions, and lava domes on the flanks.

Activity and monitoring: Sakurajima has frequent eruptions and persistent ash emissions. Eruptions range from minor explosions and steam plumes to larger events that can disrupt air traffic and deposit ash over nearby towns. The activity is continuously monitored by the Japan Meteorological Agency, which issues alerts and guidance for residents and visitors.

Human context and tourism: The volcano dominates the landscape of Kagoshima City and is a prominent tourist site with viewing points, a volcano museum, and access via ferries and roads from the city. The name Sakurajima translates to “cherry blossom island,” reflecting its cultural position as a symbol of the region.
