The quake was centered off the east coast, 91 miles off the town of Guiuan in Samar province at a depth of about 20 miles, USGS said.
The tsunami warning was issued for the Philippines, Japan, Indonesia, Taiwan, Papua New Guinea and other islands in the Pacific including the U.S. state of Hawaii.
The NOAA Tsunami Center later lifted a warning for Japan, Taiwan and several other Pacific islands.
"Strong earthquake here in Taft, Eastern Samar! And it lasted very long too!" Samar congressman, Ben Evardone, told reporters via text message.
An official at the Philippines' Volcanolgy Institute said he expected damage had been caused in Samar province but he had yet to receive any reports.
"If you are anywhere near the coast I recommend that you head to higher ground," Paul Caruso of the USGS told Sky TV by telephone when asked about a threat of a tsunami hitting the coast of the Philippines.

I wish everyone is safe coz I have experienced the quake awhile ago !!! and it was VERY VERY SHOCKING !!!! I thought my sister was just moving the bed when it became very serious but before that, it has rained already and now the rain is getting worse !!! Walls were shaking and my mother was calling the Lord's name (which she used to do) and when I went outside I saw the CRACKS on our house' walls !!!! when the power went off then rain was still pouring outside, I realized how much I wasted time to WORK FOR MY SALVATION !! Then I told myself I am not yet really ready for the END OF THE WORLD (which I have read a lot on my News Feed on Facebook, they were FLOODING UPDATES ABT IT) and to face the Lord Jesus!!! I think that was the WORST earthquake I've ever experienced in my whole existence, now my headache gets worse Let us PRAY !!!
KEEP SAFETY EVERYONE !!!
