Volcanic Alert Level Raised to 3 for Mt. Shinmoedake, Access Prohibited
The alert level for Mt. Shinmoedake has been raised to Level 3, prohibiting access to the area due to increased volcanic tremors and signs of crustal movement. The Japan Meteorological Agency emphasizes the risk of volcanic ejection within a four-kilometer radius, urging caution for nearby residents.
The Japan Meteorological Agency raised the volcanic alert for Mt. Shinmoedake to Level 3 on March 30, 2025, banning visitors from entering the area. Previously at Level 2, which only limited access to the volcanic vent, this is the first increase in alert level since June 2018. The agency warns people to stay vigilant due to the potential ejection of large volcanic rocks within a four-kilometer radius from the vent.
Since late October 2024, the mountain has experienced fluctuating volcanic tremors, with an increase noted just before the alert upgrade. On March 30, 2025, 246 tremors were recorded within 24 hours, indicating heightened volcanic activity. Furthermore, crustal deformation has been observed, suggesting a swelling of the mountain’s structure.
Tomoyuki Kanno, director of the agency’s Volcanic Observation Division, cautioned, “If an eruption occurs, it is possible that small ash deposits and small cinders may fall beyond the four-kilometer range. People need to be cautious.” This statement emphasizes the need for continued monitoring and public safety as volcanic conditions evolve.
The elevation of the volcanic alert for Mt. Shinmoedake to Level 3 marks a significant increase in potential hazards to the surrounding area. With recorded volcanic tremors and observed crustal movements, authorities stress the importance of caution for those near the mountain. Public access to the area is restricted to ensure safety in light of potential eruption risks.
