The 6.8 magnitude earthquake that struck the Tyva republic in Russia’s East Siberia on Sunday will trigger a new series of earthquakes in the region, a Russian scientist said.
“Judging from the data received from our stations, this is not the continuation of the Tyva earthquake that occurred in late 2011 with its epicenter at the Academician Obruchev Ridge but signals a new series of earthquakes,” said Viktor Seleznyov, director of the Geophysical Institute at the Siberian branch of the Russian Academy of Sciences.
The earthquake, the second powerful tremor in East Siberia in the past two months, had its epicenter located 107 km (66 miles) east of the city of Kyzyl near the border with Mongolia, at a depth of 15 km. The earthquake struck at 10:20 a.m. Moscow time (06:20 GMT) with a magnitude of 6 to 7 points in the epicenter.
The earthquake caused no casualties or damage, according to preliminary data reported by the Russian Emergencies Ministry.
The previous earthquake with a 6.7 magnitude occurred in December 2011 in the Kaa-Khemsky district of Tyva, some 100 km east of the city of Kyzyl, at a depth of 10 km. The tremor caused no destruction or casualties.
The next earthquake was expected to strike closer to Lake Baikal. Normally, a fault that becomes active in one area causes a series of decreasing tremors by their magnitude, he said.
“In this case, it is most likely that some neighboring fault became active near the previous one. This means that Tyva will now be rattled by two series of earthquakes simultaneously,” he said.
