Three Eruptions of Sakurajima Volcano in One Day Launch Ash Columns Over 4 Thousand Meters and Directly Affect the City of Kagoshima, Japan
Three volcanic eruptions were recorded on Thursday, May 15, at Sakurajima volcano, located in Kagoshima Prefecture, Japan. The smoke columns reached over 4,200 meters in height and were seen from distant points. The activity impressed residents and led to immediate impacts in the city.
Eruptions Throughout the Day
The first eruption occurred at 10:14 AM local time. The ash column generated rose to over 2,400 meters above sea level and moved to the southeast. Shortly thereafter, at 11:35 AM, a second eruption raised the column to over 4,200 meters, also to the southeast.
Later in the evening, at 9:38 PM, the third eruption of the day launched a new ash cloud to over 3,600 meters. In this case, the movement was to the east. The sequence of explosions reinforced the alert for risks in the area.

Ash Affects Visibility in the City
The city of Kagoshima, which is close to the volcano, was directly affected. Ashfall was recorded in various areas of the city, making visibility difficult on streets and roads. Drivers and pedestrians faced challenges in moving about due to the amount of material in the air.
Authorities reported that the alert level was maintained at level 3 on a scale of five levels. This level indicates that precautions need to be taken. Thus, access was restricted within a 1-kilometer radius of the crater due to the possibility of more severe explosions.
Possible Impact in Miyazaki
Experts warn that, depending on the direction and intensity of the winds, some light ashfall may occur in the neighboring prefecture of Miyazaki. The recommendation is for the population to follow updates from the authorities and avoid approaching the risk area.
Volcano Active for Centuries
Sakurajima is one of the most active volcanoes in Japan and is classified as a stratovolcano. It sits within the Aira Caldera, north of Kagoshima Bay. This caldera was formed about 22,000 years ago after a massive eruption that caused pyroclastic flows.
According to experts, Sakurajima began forming approximately 13,000 years ago. Originally, it was an island, but a major eruption in 1914 eventually connected its base to the Osumi Peninsula.
Since then, it has shown frequent activity, with records dating back to the 8th century. Continuous activity has been observed, without interruptions, since March 2017.
Social Media Records
Photos and videos of the eruptions circulated quickly on social media, showcasing the power of the natural phenomenon. The images highlight the dense ash columns and the effects on the region’s sky, catching the attention of internet users across the country.
Authorities continue to monitor the volcano and update the public on any changes in activity levels.
