The biggest single death toll was reported by a local administrative officer in Sintku township — on the Irrawaddy River near the quake's epicenter — who told The Associated Press that six people had died there and another 11 were injured.
He said some of the dead were miners who were killed when a gold mine collapsed. He spoke on condition of anonymity because local officials are normally not allowed to release information to the media.
Rumors circulated in Yangon of other mine collapses trapping workers, but none of the reports could be confirmed.
According to news reports, several people died when a bridge under construction across the Irrawaddy River collapsed east of Shwebo. The bridge linked the town of Sintku, 40 miles north of Mandalay on the east bank of the Irrawaddy, with Kyaukmyaung on the west bank.
The website of Weekly Eleven magazine said four people were killed and 25 injured when the bridge, which was 80 percent finished, fell. The local government announced a toll of two dead and 16 injured. All of the victims appeared to be workers.
However, a Shwebo police officer, also speaking on condition of anonymity, said just one person was confirmed dead from the bridge's collapse, while five were still unaccounted for.
Weekly Eleven also said two monasteries in Kyaukmyaung collapsed, killing two people.
"This is the worst earthquake I felt in my entire life," Soe Soe, a 52-year-old Shwebo resident, told The Associated Press by phone.
She said that the huge concrete gate of a local monastery collapsed and that several sculptures from another pagoda in the town were damaged.
Other damage was reported in Mogok, a major gem-mining area just east of the quake's epicenter. Temples were damaged there, as were some abandoned mines.
