Background

Only 2 volcanoes on Chirpoi Island have been historically active: The symmetrical Cherny volcano which forms the highest peak erupted 2 times. The second, younger and more active volcano is Snow. Snow volcano formed between 1770 and 1810 and is composed almost entirely of lava flows, many of which have reached the sea on the southern coast.
There are no historical eruptions on Brat Chirpoev, but its youthful morphology suggests recent strombolian activity.
