ABSTRACT Data on a caldera discovered in 2006 are reported. The caldera formed in southern Kamchatka during Eopleistocene time (1.2 to 1.5 Ma). The caldera boundaries have been reconstructed and its dimensions determined (approximately 15-25 km). The area of study contains several groups of thermal springs: the Bol'she-Bannaya, Mal. Bannaya, Karymchina, Karymshina, and VerkhneParatunka ones. The largest are the Bol'she-Bannaya springs; these were investigated extensively by many different methods during the 1970s. The reconstruction of the boundary to the large caldera that exists in the area
