Lake Karymskoje ( Russian: Кары́мское о́зеро ) is a crater lake on the Kamchatka Peninsula in the far east of Russia . The lake is located near the east coast of the peninsula, 115 km north-northeast of the city of Petropavlovsk-Kamchatsky .
The lake was formed in the two calderas Odnoboki and Akademija Nauk of the Akademija Nauk volcano . The approximately circular lake has a length in north-south direction of 4.1 km and in east-west direction of 3.9 km. The 613 m high and up to 80 m deep lake is enclosed by a caldera rim, which reaches a maximum height of 1180 m . In the north, the lake is drained from the Karmyskaya to the east coast of Kamchatka, 27 km further east. The 1536 m high volcanic cone of Mount Karymski is 5.3 km from the northern shore of the lake.
history
In 1976 a freshwater form of sockeye salmon was relocated from Lake Kronotskoye to Lake Karymskoye, which was still ecologically intact at the time.
On January 2, 1996, a series of powerful underwater explosions occurred in the northern part of Karymskoye Lake. The subsequent eruption column reached a height of 8 km. A peninsula with an eruption vent formed on the northern edge of the lake. During the explosions, the water temperature of the originally ice-covered lake heated up to 25 ° C, the pH value fell from 7.5 to 3.1–3.2. The mineralization increased from 0.1 g / l to 0.9 g / l. Volcanic activity declined by April of the same year.
