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.

A tsunami advisory was issued late Tuesday for portions of coastal British Columbia after one of the most powerful earthquakes in recent history struck off the Kamchatka Peninsula in eastern Russia.
