Manila: Three major earthquakes measuring between magnitude 7.3 and 7.4 hit the southern Philippines early on Saturday, seismologists said, but there were no reports of damage and no tsunami warning was issued.
The underwater quakes struck at a depth of between 575 and 605 kilometres, just over 100 kilometres southwest of Cotabato, in Mindanao, said the US Geological Survey.
The Hawaii-based Pacific Tsunami Warning Center said no destructive tsunami was generated by the quakes, the first of which hit at 6:08am (2208 GMT Friday).
“It was kind of mild,” said Monisa Tulawie, a staff member at the Cotabato city mayor’s office, who told AFP she felt one of the quakes.
Other residents contacted by phone were unaware of what had happened, saying they had not been woken by the tremors.
