The quake's epicentre was recorded at 1:20 pm local time (0620 GMT) in the republic of Tuva about 107 kilometres (66 miles) from the town of Kyzyl, which saw tremors of a similar magnitude on December 27. The remote and scarcely populated republic on the Mongolian border is one of Russia's most seismically active regions along with its Pacific Ocean coast. The regional emergencies ministry said the quake was felt throughout the Tyva and neighbouring regions but caused no casualties or resulted in any serious structural damage, the RIA Novosti news agency reported. But several locals reported their apartment windows breaking and books and other items falling off shelves, with a series of tremors lasting four or five minutes.
