آتشفشان Klyuchevskaya در کامچاتکا در شرق دور سرزمین روسیه ، آتشفشانی است از نوع " استرامبولی" که پس از آرامشی یکماهه در آخر روز ماه نوامبر 2010 فوران ستون خاکستر سوزان را به بلندی بیش از 7.9 کیلومتر از رویه ی دریا از سر گرفت . Half veiled in darkness by the long shadows of winter, Russia’s Klyuchevskaya volcano sends a plume of ash and steam over the snow-bound landscape. Located on the geologically active Kamchatka Peninsula in far eastern Russia, Klyuchevskaya is the region’s highest and most active volcano. Its current eruptive period started in August 2009. The Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite acquired this image on January 8, 2011. The sharp, triangular shadow west of Klyuchevskaya is probably being cast by Kamen, a towering, steep-sided volcano that is just south of Klyuchevskaya.
