Great Earthquakes In Diverse Places
Earthquake strikes Philippines
A 5.1-magnitude earthquake hit the southern Philippines early Sunday,
the US Geological Survey (USGS) said, but there were no immediate
reports of damage and no tsunami warning.
The quake struck Mindanao island at a depth of 10 kilometres (6.2
miles), 55 kilometres (35 miles) southeast of Surigao City -- the
capital of Surigao del Norte province -- at 2:37 am (1837 GMT
Saturday), the USGS said.
The Philippines is an archipelago of more than 7,000 islands on the
Pacific "Ring of Fire", where continental plates meet, causing frequent
seismic and volcanic activity.
Three major earthquakes of magnitudes between 7.3 and 7.4 took place
underwater near Mindanao on a single morning in July, shaking the
island but causing little damage.
The last major earthquake to cause widespread death and destruction in
the Philippines was in 1990, when a 7.7-magnitude quake killed 2,400
people in the country's north.
