July 13 (Reuters) - An earthquake of 5.5 magnitude struck
northern Mindanao in the south of the Philippines early on
Saturday, injuring 25 people and causing damage to several
houses, buildings and infrastructure, Philippine authorities
said.
The Philippine Institute of Volcanology and Seismology said
the quake, which was initially reported as being of 5.8
magnitude by the United States Geological Survey (USGS),
occurred at 4:42 a.m. local time and its epicentre was situated
in Carrascal, in the Surigao Del Sur area.
There was no tsunami warning from the Hawaii-based Pacific
Tsunami Warning Center immediately after the quake.
Philippine disaster officials said 25 people suffered minor
injuries and were treated at a hospital in the town of Madrid.
The tremor caused the ceiling of a church to collapse and it
slightly damaged several houses, a government building and a
public market, according to disaster officials. Cracks also
appeared on a bridge but it remained passable.
The Philippines is prone to natural disasters arising from
its location on the seismically active Pacific "Ring of Fire", a
horseshoe-shaped band of volcanoes and fault lines that circles
the edges of the Pacific Ocean.
It is also hit by an average of 20 typhoons a year, bringing
heavy rains that trigger deadly landslides.
