Crater lake. View of a bright blue crater lake in the caldera of Maly Semiachik,an active volcano. A caldera is a basin-shaped depression caused by volcanic subsidence. The lake is highly acidic and is heated by the volcano. The bright blue colour of the lake is due to the complex combinations of chemicals present in the water. Maly Semiachik is part of the Karymsky group of volcanoes,on Russia's Kamchatka peninsula | |
