Akademia Nauk (Russian: Академия Наук - Academy of Sciences) is a volcano located in the southern part of Kamchatka Peninsula, Russia, next to the stratovolcano of Karymsky.^[2] The volcano is filled with a few calderas, and the most notable one is known as Karymsky Lake (named after Karyms).^[3]

The volcano is named after the Росси́йская Акаде́мия Нау́к, the Russian (Soviet) Academy of Sciences. It last erupted on 2-3 January 1996, which continued through the end of April.^[2]

1996 eruption

On 2 January 1996, Akademia Nauk erupted. Eruptive pulses from the bottom of Karymsky Lake ejected steam and ash columns in the air every five to six hours for the 18 hours that followed, releasing approximately 30 to 40 million tons of highly acidic pyroclastic material in the air, tsunamis up to 20 meters (65 feet) also occurred. Much of the material, which was rich in sodium, sulfates, calcium, and magnesium, collapsed back into Lake Karymsky, changing its pH from 7.5 to 3.2 (moderately acidic).^[4]
