A slow release of official information left the actual extent of the damage unclear after Sunday morning's strong quake. Myanmar has a poor official disaster response system, despite having lost upward of 140,000 people to a devastating cyclone in 2008.
Myanmar's second-biggest city of Mandalay reported no casualties or major damage as the nearest major population center to the main quake Mandalay lies about 117 kilometers (72 miles) south of the quake's epicenter near the town of Shwebo.
Smaller towns closer to the main quake's epicenter were worse hit.
The area surrounding the epicenter is underdeveloped, and casualty reports were coming in piecemeal, mostly from local media. The region is a center for mining of minerals and gemstones, and several mines were reported to have collapsed.
The evening news on state television showed Vice President Sai Maul Hkam visiting the town of Thabeikyin, where the report said damage included 102 homes, 21 religious buildings, 48 government offices and four schools. The town, a gold-mining center, is near the quake's epicenter and had casualties of three dead and 35 injured. The report brought total officially confirmed casualties to six killed and 64 injured.
Independently compiled tallies suggested a death toll of about a dozen.
