The first historical eruption of Kambalny volcano began on March 24, 2017 with a powerful ash emission up to 6 km above sea level from the pre-summit crater. According to tephrochronology, it is assumed that the strong eruptions of the volcano occurred 200 (?) and 600 years ago. The maximum intensity of ash emission occurred on 25–26 March: uninterrupted plume laden with ash particles spread over several thousand kilometers, changing the direction of propagation from the volcano from the south-west to the south and south-east. On 27–29 March, the ash plume extended to the west, on 30 March – to the southeast, and on April 02 – to the east of the volcano. On March 31 and April 01, the volcano was relatively quiet. The resumption of the volcano activity after two days of rest was expressed in powerful ash emissions up to 7 km above sea level. A small ash plume was noted on 04 April, and powerful ash emissions up to 7 km above sea level occurred on 09 April. The area of ashes on the land was 1300 km2, the total area covered by ash falls, for example, on 25 March, – 650 thousand km2. To observe the Kambalny volcano eruption we used mainly satellite images of medium resolution available in the information system "Monitoring activity of volcanoes of Kamchatka and Kurile Islands" (VolSatView).
