CEBU - A powerful earthquake jolted three popular central Philippine islands Tuesday, killing at least 32 people, tearing down buildings and triggering landslides.
Fifteen of the confirmed fatalities were in Cebu, the second most important city in the Philippines and a gateway to some of the country's most beautiful beaches, civil defence office spokesman Reynaldo Balido told reporters.
The 7.1-magnitude quake caused centuries-old churches and modern buildings to crumble, while major roads were also ripped open and blocked by landslides.
"I was fast sleep when suddenly I woke up because my bed was shaking. I was so shocked, I could do nothing but hide under the bed," Janet Maribao, 33, a receptionist in Cebu, told AFP.
The governor of Bohol reported that at least 16 people had died there and more than 100 others were injured, while one person was confirmed killed on the neighbouring island of Siquijor.
All the areas are famed for their idyllic white sands and turquoise waters.
Balido and others involved in the relief and rescue operations warned the death toll would climb, with the full extent of the damage yet to be assessed.
Nevertheless, they expressed relief the earthquake occurred on a public holiday, meaning there were fewer people than normal in many of the major buildings that suffered damage.
The quake struck at 08:12 (0012 GMT) near Balilihan, a town of about 18,000 people on Bohol, at a depth of 20 kilometres (12 miles), the USGS reported.
The town lies across a strait about 60 kilometres from Cebu.
Cebu, with a population of 2.5 million people, is the political, economic, educational and cultural centre of the central Philippines.
It hosts the country's busiest port and largest airport outside of the capital Manila. It also has a major ship building industry.
A university, a school and two shopping malls sustained major damage in the quake.
Three of the people who died in Cebu were crushed to death in a stampede at a sports complex, where poor people had gathered to collect regular government cash handouts, according to the the provincial disaster council chief, Neil Sanchez.
"There was panic when the quake happened and there was a rush toward the exit," Sanchez told AFP.
He said two other people were killed when part of a school collapsed on a car they had parked in, while four others died at a fish market that crumbled.
The Philippines' oldest church, Cebu's Basilica Minore del Santo Nino, was badly damaged, according to Balido, the civil defence spokesman.
It was first built in the 1500s by Spanish colonisers, although its current stone structure dates back to the 1700s.
