The epicentre is reported to have been 234km of Nikol'Skoye, Russia, among the Komandorski islands of the Bering Strait.
A tsunami advisory has been issued by the US NWS for residents of the nearby Aleutian Islands, Alaska.
Initial automated reporting systems indicate the quake happened at a depth of about 10km, potentially sending ripples through the seafloor above.
The Joint Australian Tsunami Warning Centre issued an alert on Tuesday morning confirming there is no threat to Australia.
"An undersea earthquake of magnitude 7.6 has occurred at 9.34AM AEST on Tuesday 18 July 2017 near the Bering Sea," it reports.
"There is no tsunami threat to the Australian mainland, island or territories.
"No further updates will be issued unless the situation changes."
The quake is in the Bering Strait, on the Russian side of the channel which separates it from Alaska. The Komandorski and Aleutian Islands form a chain between the two continents.
The region is sparsely populated, prompting the US Geological Survey's automated threat analysis system to report a 'green' level of threat - indicating low human impact.
A magnitude 6.2 shock was recorded in the same area yesterday.
