Massive earthquake in Russia's far east - Felt in Moscow and parts of China, India and Japan

- First investigation of Samara show damage to at least 17 buildings. But it is not clear whether all of them are caused by the earthquake.
At 14.56 UTC, a very strong aftershock, again a very deep one, occured several hundred km south of mainshock epicenter. It was also felt with a weak intensity on Kamchatka, Sakhalin and parts of Honshu. (see Event Page)

- A large crack also appeared in a bridge in Jakutsk in eastern Siberia, only 1500 km west of the epicenter. Samara and Moscow are more than 6000 km east of the epicenter.

- Some damage reports arrive from Moskow and Samara, where a few buildings cracked. One building in Samara suffered major damage.
In St. Petersburg, one person was sick due to the shaking of the office tower.

- An other country, feeling this quake, is Kazakhstan. 20 people in Uralsk in western part of the country reported authorities they felt it.

- Seems that this quake was felt over the whole Eurasian plate. Russian media report that also some people in Romania felt it. We received reports from Finland and Denmark and a perso from Italy gave their report to ESMC.
In St. Peterburg one more building was evacuated. Both towns, Moscow and St. Petersburg, usually do not have any earthquakes. So people are frightened if it happenes.
There are still no news about damage from Kamtchatka. But usually those buildings widestand larger intensities than V, so no heavy damage is expected.

- Many parts of China were also affected by the quake. People from different provinces said they felt the quake, among them Heilongjiang, Gansu, Hubei, Chongqing, Jiangsu and Sichuan. No damage was reported from China.

- In Moscow at least two offica buildings were evacuated due to the quake. Several hundred people had to leave their workplace for some time. There are no damages reported, but some people in Moscow said they experienced an aftershock. No quake was registered around Moskow.

- Now a reader from Finland told us that this quake was felt there.

- No tsunami was registered on russian coast so far and the tsunami warning was lifted.
Russian newspaper confirm that this quake was also felt in St. Petersburg on Baltic Sea.

- We also received reports of people in Alaska and Canada who might have felt this quake. If you also felt it, please tell us.
So far, there are no reports of damage from Kamtchatka. There it was felt with moderate intensity. Also parts of western Siberia experienced a moderate shaking. People in Moskow and Tomsk report a weak shaking.
India and Japan also experienced only a weak shaking.

- In Petropavlosvsk this quake caused panic. People ran out of their buildings, schools were evacuated.

- The earthquake was felt in many parts of Russia, including Siberia and Moscow. Also people in Japan and India felt this quake. There is a tsunami warning for the russian pacific coasts.

– There exists a very very low tsunami threat from this M8.2 off Kamchatka if the 600km depth is correct.

- The cool subducting plate off the Pacific, slowly moves down into the mantle, and these bits of old crust can still be brittle enough to make big earthquakes, even 600km down.
