The Krasheninnikov Volcano in Russia’s Far East has erupted for the second time in 24 hours, launching a massive ash plume 4 kilometers into the sky. Following an earlier 6km blast, the rare double eruption has stunned volcanologists and triggered aviation alerts across the Kamchatka Peninsula.

The Krasheninnikov volcano’s first eruption in centuries is believed to have been triggered in part by the massive earthquake a few earlier.

Officials believe a volcano that erupted in Russia after hundreds of years may be connected to a huge earthquake last week. See video and photos.
