"We have been told by the director of Relief and Resettlement Department that there were seven dead and 45 injured as of late Sunday evening. The figure could fluctuate," said Ashok Nigam, the U.N. development program's resident representative. He told The Associated Press that U.N. agencies had offered aid but "no formal request has been made yet."
Myanmar's second-biggest city of Mandalay is the nearest population center to the main quake but reported no casualties or major damage. Mandalay lies about 117 kilometers (72 miles) south of the epicenter near the town of Shwebo, and the smaller towns in the area that is a center for mining of minerals and gemstones were worse hit.
State media's Sunday evening news said damage included 102 homes, 21 religious buildings, 48 government offices and four schools in the town of Thabeikyin. The gold-mining town is near the epicenter and had three dead and 35 injured.
The official tally overall is six killed and 64 injured, while independently compiled tallies say about a dozen people died.
An official from Myanmar's Meteorological Department said the magnitude-6.8 quake struck at 7:42 a.m. local time.
The disaster is the second to strike Myanmar's north in three days. On Friday, a tanker train derailed about 128 kilometers (80 miles) north of Shwebo, and at least 25 people were killed when overturned carriages burst into flames as they were trying to skim fuel from them.
