sakurajima volcano in southwestern japan erupted, blasting ash 1.2 miles into the air. The eruption occurred at 0905Z on October 12, 2023, with the volcanic ash reaching a height of 8,000 feet (FL080). The ash was observed extending to the south. This event is part of the ongoing activity at Sakurajima, which has been active for thousands of years, with meaningful eruptions shaping its landscape. The volcano’s most recent major eruption was in 1914, which connected the island to the Osumi Peninsula.

Sakurajima, located in southwestern Japan, recently experienced an eruptive event that sent ash plumes soaring 1.2 miles into the air. The eruption,occurring at 0905Z on October 12,2023,with volcanic ash reaching a height of 8,000 feet (FL080),is part of the volcano’s ongoing activity. We sat down with Dr. John Corridor, a renowned volcanologist, to better understand this event and its importance.
Recent Eruption Details
Editor: Can you provide some details about the recent eruption at Sakurajima?
Dr. John Corridor: The latest eruption at Sakurajima occurred on October 12, 2023. It released a meaningful amount of ash that reached an altitude of approximately 8,000 feet. The ash plumes were noted to extend predominantly to the south, causing concerns for local air traffic and populations downwind [[1](https://japannews.yomiuri.co.jp/society/general-news/20220724-46888/)].
Past Activity of Sakurajima
Editor: How does this eruption fit into Sakurajima’s broader history of volcanic activity?
Dr. John Corridor: Sakurajima has been an active volcano for thousands of years. Its most notable activity includes the major eruption in 1914,which altered the landscape by joining the initially separate islands together [[2](https://volcano.si.edu/showreport.cfm?doi=GVP.WVAR20241106-282080)]. Events like the one observed recently are part of its ongoing eruptive cycle and contribute to its geological evolution.
의를 Impact and Response
Editor: What are the potential impacts of volcanic eruptions like this on the surrounding area, and how are they managed?
Dr.John Corridor: Eruptions at Sakurajima can have significant impacts on local communities, disrupting transportation, and affecting air quality. The Japanese authorities are well-prepared and often raise alert levels to mitigate these impacts [[1](https://japannews.yomiuri.co.jp/society/general-news/20220724-46888/)]. It is crucial for residents to follow safety guidelines and for authorities to monitor the situation closely.
Monitoring and Forecasting
Editor: What kind of monitoring and forecasting methods are used to track Sakurajima’s activity?
Dr. John Corridor: Advanced monitoring systems are in place to detect precursor signs of eruptions.Instruments like seismographs, GPS, and gas sensors continuously collect data to predict volcanic activity. This information is used by agencies like the Japan Meteorological Agency to issue timely warnings and alerts [[1](https://japannews.yomiuri.co.jp/society/general-news/20220724-46888/)].
Long-term Implications
Editor: What are the long-term implications of frequent eruptions on the geomorphology and ecology of the region?
Dr. John Corridor: Frequent eruptions at Sakurajima continue to shape the landscape by depositing ash and lava. Over time, these accumulations can alter river courses, create new landscapes, and affect local ecosystems.This dynamic interaction between volcanic activity and the environment highlights the importance of studying volcanic regions to understand long-term geological processes.
