MANILA, Oct. 16 (Xinhua) -- At least 107 people have been confirmed dead in the powerful earthquake that severely hit central Philippine provinces of Bohol and Cebu, the country's disaster relief agency said Wednesday.
Rey Balido, operation officer and spokesman of the National Disaster Risk Reduction and Management Council, told reporters that 91 of the fatalities were from the worst-hit province of Bohol, while Cebu had nine deaths and Siquijor had one. Most of the fatalities were caused by falling debris.
Balido said the number of injured also climbed to 276 people - 166 from Bohol, 106 from Cebu, three from Siquijor, and one from Negros Oriental. Three are reported missing.
He said the number of affected population was pegged at 558,390 families or 2,841,956 families, of which 2,533 families or 12,665 persons are housed in evacuation centers.
Balido said Bohol has declared a State of Calamity and Cebu is still under a State of Calamity which was declared in August following a collision of a passenger vessel and a cargo ship that left about a hundred people dead.
The last time Bohol experienced a strong earthquake was in 1990. The offshore quake, that triggered a tsunami, also damaged structures.
The Philippines sits on the Pacific "Ring of Fire" where continental plates collide, causing frequent seismic and volcanic activity.
The worst earthquake in the country happened on Aug. 16, 1976 after a tsunami caused by a quake killed between 5,000 and 8,000 people in the Moro Gulf region in southern Philippines.
