YANGON, Myanmar (November 11, 2012)--A strong earthquake struck northern Myanmar Sunday, 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, and had a depth of just 6 miles.

It hit 72 miles north of Mandalay, Myanmar's second-largest city.

The quake was felt in Bangkok, the capital of neighboring Thailand.

It came just a week ahead of a visit to Myanmar by President Barack Obama.

Mr. Obama will be the first U.S. president to visit the one-time pariah nation, which is emerging from decades of military rule.
