In June 12, 2009, the volcano Saluchev on Matua Island in the Kuril Islands erupted, and the eruption began to spread after June 15, after which the height of the eruption reached 10,000 meters and began to affect aircraft operations.
From the image captured on June 22, 2009, we can confirm that the crater after the eruption is larger than the one before the eruption, the diameter of the crater after the eruption is about 390 m, and the diameter before the eruption is about 350m.
Left: June 19, 2009 (after the eruption). Right: March 14, 2007 (before the eruption).
The color image is created from the images of PRISM and AVNIR-2, which are the sensors of "Daichi", and you can
