According to the USGS, the earthquake occurred about 111km east of the Russian city of Petropavlovsk- Kamchatsky, with a depth of 39.5km. This area is considered the administrative center of Kamchatka region.
The USGS had previously estimated the intensity of the earthquake at 7.5 degrees richter and downgraded it to 7.1 degrees richter shortly thereafter.
The Pacific Hurricane Warning Center (PTWC) warned that the earthquake could cause 1m high "dangerous" waves along some of Russia's nearby coasts.
PTWC added that Hawaii and a series of other islands in the Pacific region may also see heavy but not strong waves, the waves are estimated to be 30cm below.
In July, one of the strongest ever recorded seismic events occurred off the Kamchatka peninsula, causing a 4m high wave of songisms across the Pacific Ocean and prompting evacuation orders from Hawaii to Japan.
The July earthquake prompted Japan to order nearly 2 million people to move to higher ground. Tsunami warnings were also issued across the area, before being canceled or downgraded.
The largest earthquake recorded in the area was in 2011, with a force of 8.8 on the Richter scale. This is the result of another earthquake off the coast of Japan, which reached 9.1 richter.
At the time, the earthquake in Japan also brought a Tsunami disaster in the vicinity, killing more than 15,000 people.
