A 7.4-magnitude earthquake struck off the coast of Kamchatka in Russia’s Far East on Saturday (September 13, 2025), the United States Geological Survey (USGS) said.
The quake hit 111 kilometres (69 miles) east of the Russian city of Petropavlovsk-Kamchatsky, the administrative centre of the Kamchatka region, at a depth of 39.5 kilometres, according to the USGS.
The survey earlier gave a magnitude of 7.5 before downgrading it.
The Pacific Tsunami Warning Center said “hazardous” waves of up to one metre (3.3 feet) were possible along some nearby Russian coasts.
Japan, Hawaii and other islands in the Pacific may see waves of less than 30 centimetres, the centre said.
