Officials in coastal Narino province said they had no news
of damaged buildings or injuries, but they were still
contacting remote rural areas. Residents told local radio the
shock knocked out electricity in some areas. "For now, the checks conducted by operational units show no
reports of any impact, but we will have to wait for the results
of monitoring," said Luz Amanda Pulido, national director of
Colombia's disaster prevention office.
An aftershock of 3.8 magnitude rattled the area shortly
after the initial quake, Colombian authorities said.
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."
The quake occurred at a depth of 6.2 miles (10 km) and its
epicenter was 95 miles (155 km) southwest of the Colombian port
city of Buenaventura, the USGS said.
