A major earthquake with a magnitude of 7.4 struck off Russia’s far east on Thursday, the United States Geological Survey (USGS) said, although Russian news agencies carried no immediate reports of damage from the sparsely populated area.

The quake off Russia’s Kamchatka peninsula, which was initially measured at 7.8 before being revised downwards, struck 82 km (55 miles) west of Nikolskoye at a depth of 9 km, it said.

The Pacific Tsunami Warning Centre said hazardous tsunami waves from the earthquake were possible within 300 kilometers of the epicentre along the coasts of Russia.
