WASHINGTON, Sept 9 (Reuters) - A strong 6.8-magnitude earthquake hit near the west coast of Colombia on Sunday night, the U.S. Geological Survey said, but there were no immediate reports of serious damage.
Vindell Hsu, a geophysicist with the Pacific Tsunami Warning Center in Hawaii, told Reuters by telephone: "At this moment we are not giving any warning to any area. There might be small waves locally."

According to the United States Geological Survey (USGS) a magnitude 6.8 struck just of the coast of Colombia at 01:49 (UTC) with a depth of 10 kilometers (6.2 miles). The epicenter was located 150 km (95 miles) north, northeast of Tumaco, Colombia. 

There are reports of power outages in some cities, but there are no reports of damage to buildings, deaths or injuries. The USGS says that some "moderate" damage may exist near the coastline of southwest Columbia.

The National Oceanic and Atmospheric Administration (NOAA) has not issued a tsunami warning saying there is "no destructive widespread tsunami threat based on earthquake historical data," but that "small waves could be generated locally."
