A magnitude-6.1 earthquake shook part of southern Philippines on Wednesday afternoon, the United States Geological Survey (USGS) said.

The quake, which struck at 2:47 p.m. local time (0647GMT) from a depth of 69.6 kilometers, was traced some 115 kilometers south- southeast of Hinatuan town in Mindanao's Surigao del Sur province, the USGS said on its website.

The tremor was felt as far as Davao City to the south and Butuan City to the north for at least 10 seconds, local residents affected by the tremor told Xinhua.

"It was so strong that I was even roused from my sleep," said Gladdys Briones, a housewife from Tagum city.

According to the Philippine Institute of Volcanology and Seismology, the quake was too deep to cause any damage or injuries. No tsunami warning was issued.
