Both incidents could be connected to the huge earthquake that rocked Russia's Far East last week, that triggered tsunami warnings as far away as French Polynesia and Chile, and was followed by an eruption of Klyuchevskoy, the most active volcano on the Kamchatka Peninsula.

Russia’s Far Eastern Kamchatka Peninsula has been rocked by yet another earthquake, this time a magnitude 6.0 tremor, just six days after a catastrophic 8.8 magnitude quake shattered the region and sent tsunami warnings rippling across the Pacific.
