Oct 29 (Reuters) - The death toll from a strong earthquake
in the southern Philippines has risen to seven, disaster and
police officials said on Tuesday, as aftershocks continued to
jolt many parts of Mindanao.
The 6.6 magnitude quake hit early on Tuesday, damaging
buildings, toppling power lines and triggering landslides in the
central area of the Philippines' southern island.
A seven-year-old child and his 44-year old father were among
those who were killed in the North Cotabato province after they
were struck by a boulder, disaster officials said.
Authorities said the death toll could rise further because
many injured were not immediately brought to hospitals.
"It was depressing to see the damage left by the
earthquake," Abril Espadera, a disaster official in North
Cotabato, told Reuters, as he recalled seeing collapsed homes
and demolished buildings in the province, including schools.
Smaller tremors rattled nervous residents throughout the day
and those who were afraid to return to their homes set up tents
to shelter near school yards, Espadera said.
In Magsaysay town in Davao del Sur province, rescuers were
trying to recover three bodies after landslides in two separate
towns swallowed parts of agricultural areas, police said.
The quake, whose magnitude was initially put at 6.7 by the
European-Mediterranean Seismological Centre, was the second
powerful quake to strike Mindanao in two weeks.
Authorities had flagged the risk of landslides after the 6.3
quake on Oct. 16 in central Mindanao that killed seven and
injured more than 200.
Earthquakes are common in the Philippines, which is on the
geologically active Pacific Ring of Fire.
Power cables swayed in Davao city, the home town of
President Rodrigo Duterte, where people rushed to open spaces,
and some fainted out of fear. The quake also triggered power
cuts in nearby General Santos city, media said.
Some schools in the area have suspended classes.
Duterte's office has called for calm as it mobilised all
government agencies to undertake damage assessment and to
coordinate rescue and relief operations.
