A powerful earthquake with a magnitude of 6.8 shook southwestern Siberia on Sunday afternoon, the second to hit the area in two months. There were no immediate reports of damage or injuries, emergency officials said. Residents of multistory apartment buildings said objects tumbled off of shelves, windows rattled and chandeliers swayed during the quake, the RIA Novosti news agency reported. The earthquake hit about 100 kilometers (60 miles) east of Kyzyl, the capital of the Russian republic of Tuva, which borders Mongolia.
