Ring Of Fire Earthquake Hits Russia And US

Two earthquakes have hit the Ring of Fire area, registering magnitudes of 8.2 and 5.7 and prompting a tsunami warning.

Moscow felt tremors from the more powerful quake, causing some people to evacuate buildings despite the epicentre being more than 4,000 miles to the east.

The US Geological Survey said the epicentre of Thursday's quake was in the Kuril-Kamchatka arc, one of the most seismically active regions in the world.

Marina Kolomiyets, from the Russian Academy of Sciences, said it originated 375 miles under the sea bed in the Sea of Okhotsk, just off Russia's east coast and north of Japan.

A tsunami warning for the Sakhalin and the Kuril islands was issued, but lifted soon afterwards.

Tremors are extremely rare in Moscow, with the last recorded instance in 1977. Witnesses also reported feeling the tremors across Siberia.

"There were repercussions of the quake in Nizhny Novgorod, Moscow and Europe, in particular Romania," said Anatoly Tsygankov from Russia's Rosgidromet environmental monitoring service.

"Practically the whole continent shook."

No casualties have been reported.

A second, smaller 5.7 magnitude quake also struck the US.

It hit northern California's Plumas County at 8.47pm local time and was centred six miles west of Greenville.

Sacramento television station KCRA-TV said the tremors were felt in the city, some 145 miles south of the epicentre.

Eight aftershocks ranging from 2.6 to 3.5 magnitude were also recorded. So far, no injuries or damage have been reported.

The Ring of Fire is a horseshoe-shaped area located around the edge of the Pacific Ocean.

The vast majority of the world's volcanoes and earthquakes occur in the area because of the movement and collisions of the Earth's tectonic plates.
