The death toll in a magnitude-6.9 earthquake in the central Philippines rose to 41, with 67 people still missing and feared dead, the Office of Civil Defence said.

The toll rose after rescue teams recovered two bodies from landslides caused by February 6 quake in Negros Oriental province, 570 kilometres south of Manila.

The civil defence office said 28 were still missing in the village of Planas in Guihulngan City and 39 in the village of Solonggon in nearby La Libertad town.

Rescue operations were being hampered by strong aftershocks and intermittent heavy rains threatening to cause more landslides, authorities said.

The military has been distributing relief goods to more than 80,000 residents, who were staying in makeshift tents or evacuation centres for fear the aftershocks would cause their houses to collapse.

The quake destroyed more than 5,600 houses, while partially damaged 5,002. Many roads cracked while three key bridges in the province collapsed.

Damages caused by the tremor were estimated to cost at least 365.36 million pesos (8.69 million dollars), the OCD said, M&C reported quoting DPA.

The Philippines, located along the Pacific 'Ring of Fire,' suffered its worst earthquake in 1990 when a 7.7-magnitude tremor killed nearly 2,000 people on the northern island of Luzon.
