The Japan Meteorological Agency raised the volcanic alert for Mt. Shinmoedake to Level 3, prohibiting public access to the area. Since late October 2024, volcanic tremors have surged, prompting warnings about potential eruptions and falling ash within a four-kilometer radius. Individuals are advised to exercise caution.
On March 30, 2025, the Japan Meteorological Agency (JMA) elevated the volcanic alert for Mt. Shinmoedake to Level 3, thereby prohibiting public access to the area around the mountain, which is located in the Kirishima range across Miyazaki and Kagoshima Prefectures. This alert marks the first upgrade since June 2018, signaling heightened volcanic activity and potential eruptions.
Previously designated as Level 2, which allowed limited access to the vicinity of the volcanic vent, the Level 3 alert now urges individuals within a four-kilometer radius to remain vigilant against possible volcanic projectiles. The JMA has observed fluctuations in volcanic tremors at the site since late October 2024, with a notable increase of 246 tremors recorded within a single day leading up to the recent alert.
The agency has confirmed signs of crustal deformation indicative of swelling since 2:50 a.m. on the day of the alert. Tomoyuki Kanno, Director of the JMA’s Volcanic Observation Division, emphasized the dangers: “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.”
The recent elevation of the volcanic alert for Mt. Shinmoedake highlights an increase in seismic activity and potential eruption risks. With restricted access to a four-kilometer zone surrounding the mountain, the Japan Meteorological Agency advises heightened caution for those living nearby. This situation underscores the need for public awareness regarding volcanic hazards.
