A strong earthquake and aftershock off the coast of Russia this morning and overnight does not pose a tsunami threat to Hawaii, according to officials at the Pacific Tsunami Warning Center.

A preliminary 6.8-magnitude aftershock struck at 4:56 a.m. and was centered 218 miles west-northwest of Ozernovskiy, Russia at a depth of 387 miles, according to United States Geological Survey officials.

A 8.3-magnitude quake struck the same region last night at 7:44 p.m. Hawaii time without generating a tsunami.

Thursday's earthquake in Russia's Far East was felt as far away as Moscow, about 4,400 mileswest of the epicenter, but no casualties or damage were reported.

Marina Kolomiyets, spokeswoman for Obninsk's seismic station of the Russian Academy of Sciences, told The Associated Press the epicenter was in the Sea of Okhotsk, east of the Russian coast and north of Japan, and was 130 kilometers away from the nearest village. The epicenter was in the Kuril-Kamchatka arc, one of the most seismically active regions in the world.

Emergency agencies in the Far East issued a tsunami warning for Sakhalin and the Kuril islands, but lifted it soon afterwards. Kolomiyets said the earthquake originated  375 miles under the sea bed and with the tremors so far down they have the potential to spread quite far.

The Emergency Situations Ministry said they have not recorded any casualties or damage from the quake.

A big aftershock came about nine hours after the first quake. The Russian Academy of Sciences measured it at 7.0, while the U.S. Geological Survey put it at magnitude 6.8.

Russian news agencies reported that residents of Petropavlovsk-Kamchatsky on the Kamchatka peninsula in the Okhotsk Sea felt the first quake for about five minutes. Residents ran out of the buildings. School children were evacuated.

Tremors from the first quake were felt in Moscow, prompting some people to evacuate from buildings across the city.

Tremors are extremely rare in Moscow, the last recorded instance was in the 1977. The Russian Meteorological Service confirmed these reports but said they did not have immediate information about the magnitude of the tremors of Moscow.

Russian news agencies also cited eyewitnesses reporting strong tremors across Siberia.
