YANGON, Myanmar — A strong earthquake has struck northern Myanmar, but no injuries were immediately reported.

The magnitude-6.6 temblor hit the area at 7:42 a.m. Sunday, according to the U.S. Geological Survey. The quake had a depth of just 10 kilometres and hit 117 kilometres north of Mandalay, Myanmar's second-largest city.

The quake was felt in Bangkok, the capital of neighboring Thailand. It comes just a week ahead of a visit to Myanmar by President Barack Obama. Obama will be the first U.S. president to visit the one-time pariah nation, which is emerging from decades of military rule.
