After the Sakurajima volcano released the highest eruption alert, Mount Fuji once again caused concerns

According to the Japan Meteorological Agency, Sakurajima volcano in Kagoshima Prefecture, Kyushu, Japan continued to eruption on the 25th after a large -scale eruption occurred on the evening of the 24th. As of 9:30 am on the 25th, the volcano erupted 3 times, and the smoke and dust sprayed up to 2200 meters.

The Japan Meteorological Agency said that at 20:05 on the 24th local time (19:05 on the 24th Beijing time), an explosive eruption occurred in the mountain top of Nanyue Nanyue. About 2.5 kilometers from the crater. Sakurajima is a living volcanic island located in Lu'er Island Bay, south of Kyushu, Japan. It covers an area of ​​77 square kilometers and consists of three volcanic bodies in Beiyue, Zhongyue and Nanyue.

After the volcanic eruption, the Japan Meteorological Agency issued the highest -level five -level alarm and asked the surrounding people to avoid risks. It is worth noting that this is the second highest level alert since the introduction of volcanic eruption warning levels in 2007, and it is also the first time that the Sakurajima volcanic eruption alert to the highest level.

Sakurajima volcano is one of the most active volcanoes in Japan. It has erupted many times in recent years and has become more active. On June 28 last year, Sakurajima volcanic eruption, the formed smoke pillar was as high as 1500 meters; on January 28 this year, Sakura Island triggered a three -level eruption alert, and the smoke pillars at the time were 3400 meters. On the 17th of this month, the volcano erupted again. The height of the smoke column reached 2800 meters.

The Meteorological Department stated that starting from the 18th of this month, they have observed subtle crust changes on Sakurado Island and found that the mountains are expanding. And related geological activities have also aroused concerns about Mount Fuji.

The volcano is closely related to the earthquake, and frequent earthquakes are an important symbol of active volcanic activity. In the past two years, Japan has repeatedly monitored the earthquake centered on Mount Fuji. For example, on December 23 last year, Japan monitored the earthquake with Mount Fuji as the center of the source within 7 hours.

Mount Fuji is located about 60 kilometers southwest of Tokyo Metropolis. Some computer simulation analysis shows that if Mount Fuji erupted violently, the volcanic ash will spread eastward quickly, the Tokyo Metropolitan Circle will fall into darkness within two hours, and local transportation, air quality, and people's lives will be seriously affected.

The Japanese media reported earlier this month that the Japanese Police Department has begun to prepare for the possible eruptions of Mount Fuji and distribute the purchase of dust masks to the local police department.Source: Xinmin Evening News
