Fresh satellite images have captured one of Russia's most active volcanoes melting snow from the inside out as volcanic heat continues to seep through the frozen landscape of the Kamchatka Peninsula.

Images captured by the Landsat 9 satellite on April 23 show dark channels of ash and volcanic debris cutting through the snowy slopes of Shivelyuch volcano in far eastern Russia.
