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 powerful earthquake struck Wednesday off Russia's Far East coast, flooding a fishing port with waves from a tsunami, cutting power to a few areas and sending some panicked residents fleeing buildings but causing only a few injuries.
