Magnitude of Siberian quake raised to 9.5.

The magnitude of the quake that struck south-eastern Siberia late on Tuesday has been raised to 9.5, according to Russia’s emergencies minister Sergey Shoigu.

The quake is the strongest ever to be detected in the region he said. There have been no reports of damage or casualties since the tremor - initially reported as 6.7 on the Richter scale - struck a sparsely populated area in the Republic of Tyva near the Russian-Mongolian border. However Shoigu expressed doubts that there has been no damage at all and has ordered the authorities to stay on the alert for any aftershocks that may follow.
