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).

Aftershocks continued to rattle Russia's Far East on Thursday, one day after a mighty earthquake struck off the country's Kamchatka peninsula, triggering tsunami alerts for millions of residents along the Pacific.

The US Geological Survey data suggested nearly 125 aftershocks of magnitude 4.4 or greater have been recorded near Russia in more than 16 hours following a powerful earthquake of 8.8 magnitude off Russia's far eastern coast.
