Lake Yanisyarvi (Russian: Янисъярви; Finnish: Jänisjärvi) is a lake in the Republic of Karelia, Russia, located north of and draining to Lake Ladoga.
The basin of this somewhat circular lake was formed by meteorite impact 700±5 million years ago during the Cryogenian period. The crater is 14 kilometers (8.7 mi) in diameter.[1]
Prior to World War II, the lake was thought to be the second known volcanic caldera in Finland (the other was Lake Lappajärvi). Both were eventually recognized as impact craters.
