A magnitude 8.2 earthquake struck off Russia's eastern coast on Friday, briefly prompting a tsunami scare but causing no casualties or substantial damage, Russian emergency authorities said.
The epicentre of the quake was located at a depth of 385 miles in the Sea of Okhotsk, 244 miles west of the nearest city, Petropavlovsk-Kamchatsky, the U.S. Geological Survey said.
The quake was felt in Petropavlovsk-Kamchatsky, the main city on the Kamchatka peninsula and home to a nuclear submarine base, and on Sakhalin island, where Russia's largest liquefied natural gas project is located.
