There was a powerful magnitude 8.7 earthquake that strucked off Russia's Far Eastern Kamchatka Peninsula on 30 July, generating a tsunami of up to 4 metres (13 feet), prompting evacuations and damaging buildings, officials said.
"Today's earthquake was serious and the strongest in decades of tremors," Kamchatka Governor Vladimir Solodov said in a video posted on the Telegram messaging app. He added that according to preliminary information there were no injuries, but a kindergarten was damaged.
