Krasheninnikov is an active volcano in the Eastern Volcanic Belt of Kamchatka. According to tephrochronological data, the last explosive eruption of the volcano was 1100 years ago, and the effusing of lava flows and the formation of a cinder-lava cone in the crater of the Northern Cone of the volcano occurred 400–600 years ago. According to satellite data from the information system “Remote monitoring of the activity of volcanoes in Kamchatka and the Kuril Islands” (VolSatView, http://volcanoes.smislab.ru), the first historical eruption of the volcano began at 16:38 UTC on August 2, 2025. The paper presents the first results of the study of the eruption during August 2–16, 2025. During this time, in the satellite images, there were constantly observed in the area of the volcano a large thermal anomaly and ash plumes that stretched for hundreds of kilometers in different directions from the volcano. As of August 12, the length of each of the three lava flows that effused from August 2 to 12 on the northwestern and eastern slopes of the Northern Cone was about 3 km, the total area of the lava flows reaching 2.7 km2. The eruption of Krasheninnikov Volcano continues.
