The Krasheninnikov Volcano in far eastern Russia erupted for the first time in more than 500 years, and experts believe it could be linked to last week’s massive earthquake.
The eruption caused a second earthquake, which led to tsunami warnings in three areas of the peninsula.
Both events are thought to be connected to an 8.8 magnitude earthquake that shook the region and caused tsunami warnings in French Polynesia and Chile.
The volcano threw up an ash plume up to 6km high overnight, but Russia’s emergency ministry said there are no threats to populated areas.
"The plume is spreading eastward from the volcano toward the Pacific Ocean," Kamchatka's emergencies ministry wrote on Telegram during the eruption.
"There are no populated areas along its path, and no ash fall has been recorded in inhabited localities."
The Kamchatka Volcanic Eruption Response Team said the volcano’s activity was decreasing but that “moderate explosive activity” could continue.
The eruption of the volcano has been assigned an orange aviation code, indicating a heightened risk to aircraft, the ministry said.
The last recorded eruption of the Krasheninnikov Volcano was in the 15th century, according to the head of the Kamchatka Volcanic Eruption Response Team.
