What Russian islands were formed by the ring of fire?

The Kuril Islands, located between the Kamchatka Peninsula and Japan, were formed by the tectonic activity associated with the Pacific Ring of Fire. This volcanic archipelago consists of about 30 islands and is known for its active volcanoes and seismic activity. Additionally, the Commander Islands, situated to the east of the Kamchatka Peninsula, are also influenced by the geological processes of the Ring of Fire.
