Karymsky volcano contained a 250-m-wide summit crater following the 1970-82 eruption. Karymsky Lake fills the 3 x 5 km wide Akademia Nauk caldera to the south in this early 1990's aerial photo. Both Karymsky and Akademia Nauk erupted simultaneously on 2 January 1996. The brief one-day eruption was the first historical eruption of Akademia Nauk, but long-term activity continued at Karymsky.
