Russia's Kamchatka Peninsula and surrounding Pacific Rim regions continued to experience seismic instability, with dozens of aftershocks being reported on Saturday by the United States Geological Survey (USGS).

Kamchatka is a 1,250-kilometre-long peninsula located in the Far East of Russia. The Pacific Ocean and the Sea of Okhotsk serve as the eastern and western coastlines of the peninsula, respectively.

An 8.8 magnitude earthquake struck off Russia's Kamchatka Peninsula on Wednesday, generating tsunami warnings across the Pacific Ocean region, the US Geological Survey (USGS) said. The epicenter was located at a depth of 20.7 kilometers (12.8 miles) and was centered 119 kilometers (73.9 miles) east-southeast of Petropavlovsk-Kamchatsky, it said.
