A strong undersea earthquake rocked western Indonesia Friday, about 190 miles southwest of the capital, Jakarta.

There were no immediate reports of injuries.

The 6.4 magnitude quake comes as recovery efforts continue from another powerful earthquake in September. It was not powerful enough to cause a tsunami, an official with Indonesia's Meteorology and Geophysics Agency, said.

In September, a 7.6 magnitude quake on the neighboring Indonesian island of Sumatra killed more than 1,100 people. The epicenter of that quake was a few hundred miles north.

The U.S. Geological Survey put the strength of Friday's earthquake at 6.5 and said it had a depth of 35 miles.
