MANILA, Oct 31 (Reuters) - A magnitude 6.5 earthquake rocked
southern Philippines still reeling from two strong tremors this
month, killing at least five people and causing previously
damaged buildings and homes to collapse.
The integrity of several buildings and homes on Mindanao
have already been weakened by a 6.3 earthquake that struck on
Oct. 16 and another 6.6 quake on Oct. 29.
A social welfare officer said five people in North Cotabato
province died due to the quake, including a village chief when
the office wall collapsed on him. This brought the number of
killed to 20 in the series of tremors since Oct. 16.
The latest quake occurred 33 km (20 miles) northeast of
Tulunan town in Cotabato province, which lies west of Davao
City, where President Rodrigo Duterte was when it happened. His
spokesman, Salvador Panelo said the Philippine leader is safe.
Police rescued 9 people who were injured after the bottom
floor of a mid-rise condominium in Davao collapsed, DZMM radio
reported.
In nearby Kidapawan city, a six-storey hotel collapsed, but
there was no one inside, Mayor Joseph Evangelista told DZMM
radio.
The Philippine Institute of Volcanology and Seismology
(Phivolcs) advised the people to remain outside their homes and
offices given the possibility of more and stronger aftershocks.
"Buildings could be totally knocked out", said Erlinton
Olavere, a science research specialist at Phivolcs.
Earthquakes are common in the Philippines, which is on the
geologically active Pacific Ring of Fire.
Duterte's office has directed all agencies and local
government units to provide the necessary assistance and
immediate relief to those affected.
