A shallow 6.6-magnitude earthquake struck Myanmar on Sunday, the US Geological Survey said.
The quake struck around 117 kilometres (72 miles) north of the country's second largest city of Mandalay at a depth of just 10 kilometres, the agency said. It initially put the magnitude of the quake at 7.0.
USGS issued a yellow alert for estimates of damage and fatalities, saying "some casualties and damage are possible" but that the impact should be relatively localised.
The quake hit at 7:42 am (0112 GMT) and was followed by two shallow 5.0-magnitude aftershocks within 20 minutes.
It struck around 572 kilometres east of the Bangladeshi capital of Dhaka, one of the world's biggest cities.
More than 70 people were killed in March 2011 when a powerful 6.8-magnitude quake struck Myanmar near the borders with Thailand and Laos.
