Provided by: NICT / Weather News
On June 22 (Saturday) Japan time, the thunder island of the Kuril Islands erupted (Raikoke To / Ryokek), before dawn.
According to the Airway and Volcanic Ash Information Center, the height of the fuming smoke seems to reach about 13,000 meters, and this can be confirmed from the weather satellite Himawari.
Raikkot Island is a volcanic island 551m above sea level, and had a large eruption in 1924 in modern times. From the Kamchatka Peninsula to the Kuril Islands are areas with active volcanic activity.

Location of Lightning port island
Possibility of affecting the flight path of the aircraft
Looking at the satellite image, it seems that the eruptive activity continues even at 11:00 on Saturday, 22nd of Japan time.
A large amount of fuming smoke is swept away by the west wind above the sky and spreads to the far east of the island. It is considered unlikely that the fumes released by this eruption will flow directly over Japan.
The fumes are concerned about the impact on the aircraft. If you fly in the atmosphere containing a lot of volcanic ash, the output of the engine that sucked it may stop, or the window glass may be damaged and you may lose sight, resulting in a serious impact on operations. .
International flights usually cruise at an altitude of 10,000 to 13,000 meters. In the vicinity of Kuril Islands, there are many major air routes connecting North America and Asia, so it is possible that aircraft scheduled to pass the east side of the island may be delayed due to route changes. If you plan to use an international flight, please check the flight status etc.
