Overview
The lake-filled Akademia Nauk caldera is one of three volcanoes constructed within the mid-Pleistocene, 15-km-wide Polovinka caldera. The eroded Beliankin stratovolcano, in the SW part of Polovinka caldera, has been active in postglacial time (Sviatlovsky, 1959). Two nested calderas, 5 x 4 km Odnoboky and 3 x 5 km Akademia Nauk (also known as Karymsky Lake or Academii Nauk), were formed during the late Pleistocene, the latter about 30,000 years ago.
Eruptive products varied from initial basaltic andesite lava flows to late-stage rhyodacitic lava domes. Two maars, Akademia Nauk and Karymsky, subsequently formed at the southern and northern margins of the caldera lake, respectively. The northern maar, Karymsky, erupted about 6,500 radiocarbon years ago and formed a small bay.
The first recorded eruption from Akademia Nauk took place on 2 January 1996, when a day-long explosive eruption of unusual basaltic and rhyolitic composition occurred from vents beneath the NNW part of the caldera lake near Karymsky maar.

About the Photo
The lake-filled Akademia Nauk caldera, seen here from the north with Kaymsky in the foreground, is one of three volcanoes constructed within a large mid-Pleistocene caldera. Two nested calderas, 4 x 5 km Odnoboky and 3 x 5 km Akademia Nauk formed during the late-Pleistocene. The first historical eruption from Akademia Nauk took take place on 2 January 1996, when a brief, day-long explosive eruption occurred from vents beneath the NNW part of the caldera lake.
