Volcano Sakurajima Triggers Intense Eruptions in Japan and Disrupts Flight Operations in Kagoshima. Understand the Risks.
The Sakurajima volcano, one of the most active in Japan, erupted strongly early Sunday morning (11/16/2025), spreading dense ash across Kyushu Island.
The explosions, which occurred at different times, launched a column of volcanic material that reached a height of 4.4 kilometers, resulting in the cancellation of flights, affecting airports, and reducing visibility in the region.
Weather authorities confirmed that the cloud spread rapidly and is expected to move northeast throughout the day, which explains the direct impact on air transport.

The Japan Meteorological Agency (JMA) reported that the first explosion occurred around 1 AM (4 PM Saturday Brasília time).
Shortly after, two more eruptions were recorded at 2:30 AM and 8:50 AM, reinforcing the instability of Sakurajima and increasing the risks for aircraft operations in Kagoshima.
Intense Eruptions of Sakurajima Affect Airports and Disrupt Flights
The successive eruptions of Sakurajima volcano caused intense ash fall at Kagoshima Airport in southwestern Japan.
As a result, airlines had to suspend about 30 flights, both arriving and departing.
Low visibility and the risk of ash ingestion by aircraft engines make air operations dangerous, which justified the immediate action of the companies.
According to the Kyodo agency, this was the first eruption with a column above 4 kilometers in almost 13 months, which reinforces the exceptional nature of the event and helps explain the sudden impact on air transport.
On the other hand, local authorities continue to monitor volcanic activity to prevent further disruptions.
Ash Cloud Advances and Is Expected to Reach Other Areas of Japan
The JMA reported that the cloud released by the volcano is moving rapidly northeast.
The official forecast points to ash fall not only in the city of Kagoshima but also in the neighboring province of Miyazaki, where residents may face accumulation of volcanic material on the streets and on vehicles.
Furthermore, the agency advised the public to avoid prolonged exposure outdoors and to protect their eyes and respiratory tracts, as particles released by eruptions are often highly irritating.
Sakurajima: One of the Most Active Volcanoes in Japan
The Sakurajima is historically one of the most active volcanoes in Japan, with constant records of explosions and ash emissions.
In 2019, it released volcanic material to a height of 5.5 kilometers, demonstrating the strength and unpredictability of its activity.
Therefore, residents and authorities live with continuous monitoring, as small and medium explosions are part of the island’s daily life.
Although frequent, the latest eruptions drew attention due to the height of the ash column and the immediate impact on the air sector, which is usually one of the first to feel the effects of these natural phenomena.
Flights, Risks, and Forecasts: What to Expect in the Coming Hours
The situation remains under enhanced observation, especially because new eruptions from Sakurajima may occur at any moment.
Thus, airlines remain alert for possible adjustments in flight schedules, while residents await updates on ash dispersion.
Finally, meteorological authorities emphasize that the volcano’s behavior still shows no signs of stabilization.
Therefore, caution is recommended, as the current activity reinforces the permanent risk that Sakurajima poses to nearby areas.
