A powerful quake in the Philippines was strongly felt in North Sulawesi province in Indonesia's northern Celebes Island on Saturday, but the Indonesian meteorology and geophysics agency did not issue a tsunami warning, an official of the agency said.
"This quake is not potential for tsunami in Indonesian territory," head of the quake and tsunami department of the agency Rahmat Triyono said.
The jolts were also moderately felt in North Maluku province of eastern Indonesia, Triyono said.
Spokesman of the National Disaster Management Agency Sutopo Purwo Nugroho, however, said the jolts did not caude damages in Indonesian territory.
There is no preliminary reports of casualties or damages triggered by the quake, he told Xinhua.
Northern parts of Celebes Island and Maluku province in central and eastern parts of Indonesia border the Philippines.
A 7.1-magnitude quake struck off the Philippine island of Mindanao at 10:39 a.m. Jakarta time with a depth of 49 km.
Indonesia is also prone to quake as it lies on a vulnerable quake-prone zone of the so-called "Pacific Ring of Fire."
