Japan: Increased volcanic activity ongoing at Sakurajima Volcano in Kagoshima Prefecture as of Feb. 14

Officials with the Japan Meteorological Agency have observed increased levels of volcanic activity at the Sakurajima Volcano in Kagoshima Prefecture as of Feb. 14. Explosive eruptive activity was observed at the Minamidake summit crater from around 18:30 Feb. 14, which produced an ash cloud rising to around 5,000 meters (16,400 feet) above the crater. The JMA has forecast heavy and moderate ashfall in areas of the Sakurajima Peninsula just to the north of the summit and light ashfall gradually spreading east-northeastward across parts of Kagoshima, Miyazaki, and far southern Kumamoto Prefectures. Large volcanic blocks and other debris have also been observed being projected around 1,000-1,300 meters (3,280-4,265 feet) from the crater.

Authorities are maintaining alert level 3 (out of 5) for Sakurajima Volcano. Despite the increased volcanic activity, authorities have not issued any mandatory evacuations for the surrounding area. People are being advised to avoid the areas around the crater due to the risk of pyroclastic flows and other volcanic debris. Additional eruptions could cause low-level seismic activity, ash clouds, and landslides in the surrounding area.

Plan for possible transport disruptions in the surrounding area, especially if a significant eruptive activity continues. Road conditions could quickly deteriorate during periods of significant ashfall, and visibility could be reduced. Officials might close roads near the volcano depending on the presence of hazardous volcanic material. Fine particulate matter ejected from the volcano could pose a hazard to flights in the surrounding airspace. Authorities might temporarily close airport facilities if significant ashfall accumulations occur.
