The western coast of Mexico was struck by a more powerful earthquake Thursday morning after a 6.5 magnitude trembler rocked the sparsely populated mountain region in Michoacan state Wednesday evening.

The second and strong earthquake that struck the western coast shook buildings, sending people out of the houses and offices, according to a Reuters report.

The US Geological Survey said that the quake was of 6.9 magnitude and was centered 127 kilometer northeast of Guerrero Negro. It occurred at a depth of 6.2 miles below the earth's surface.   

Though the magnitude of the quake was huge, the impact was dissipated since it occurred far below the earth's surface, according to a Fox report.  

Initial reports said there was no damage and casualty, and no tsunami warning had been issued.

Mexico City Mayor Marcelo Ebrard tweeted after the first quake: There were no initial signs of serious damage. Key services in the capital, including its subway system and the international airport, were operating normally.

Meanwhile, a 5.9 magnitude tremor struck the US coast, about 160 miles off the Bandon city, Ore., and no reports of damage were reported here either.

On Wednesday, a powerful 8.7 magnitude earthquake hit Indonesia raising a tsunami alert. However, authorities later clarified that reports did not indicate a tsunami threat.
