The quake occurred 111 kilometres (69 miles) east of Petropavlovsk-Kamchatsky, the administrative centre of the Kamchatka region, at a depth of 39.5 kilometres, according to the USGS.

The Pacific Tsunami Warning Centre warned that “hazardous” waves could affect Russian coasts within 300 kilometres of the epicentre.

The USGS initially reported the quake as magnitude 7.5, but later downgraded it.

Earlier in July, one of the strongest earthquakes on record struck off the Kamchatka Peninsula, generating tsunamis up to four metres (12 feet) high across the Pacific and prompting evacuations from Hawaii to Japan.

That magnitude 8.8 tremor was the largest since 2011, when a magnitude 9.1 earthquake off Japan triggered a tsunami that killed over 15,000 people.

The July quake led Japanese authorities to order nearly two million residents to move to higher ground, while tsunami warnings across the region were subsequently downgraded or cancelled.
