A volcano in far eastern Russia has erupted for the first time in more than 500 years, which experts say may be linked to last week's massive earthquake.
The Krasheninnikov Volcano in Kamchatka threw up an ash plume up to six kilometres (3.7 miles) high overnight. There are no threats to populated areas, Russia's emergency ministry said.
Hours later, another large earthquake in Russia led to tsunami warnings in three areas of the peninsula.
Both events may be connected to a massive 8.8 magnitude earthquake which hit a similar area last week, which caused tsunami warnings as far away as French Polynesia and Chile.
Russian experts had warned strong aftershocks were possible for several weeks after Wednesday's earthquake - which was one of the strongest ever recorded and saw millions of people evacuate.
