A moderately strong earthquake cracked buildings and knocked televisions and glassware from tables on Tuesday in a central Philippine province, injuring at least nine people and sending others rushing outside in panic, officials said.
The quake came a month after 58 people died in a quake on another Philippine island.
Renato Solidum of the Philippine Institute of Volcanology and Seismology said the quake with a preliminary magnitude of 5.2 struck on Tuesday morning and was centered at sea just three kilometres north of Masbate City on the island province of Masbate.
The quake, which was caused by movement in a local fault, was felt in nearby provinces.
Masbate City Mayor Socrates Tuason told The Associated Press by telephone that there were no immediate reports of major damage, and power and communications were unaffected by the temblor in his hillside city of 90,000 people.
But the quake caused an abandoned three-story building to collapse and shattered glass windows in houses and other buildings, at least two of which were cleared of people and cordoned off by police while government engineers checked their stability.
Large numbers of people rushed out of homes, offices, hospitals and schools and stayed in the streets as a number of aftershocks rattled nerves after the quake.
At least nine people were slightly injured by falling objects and collapsing walls, officials said.
"I was having breakfast with my wife when everything started to shake. The TV set and glasses fell off the table," Tuason said.
"When I got out, I saw all the people in the community were on the streets."
Disaster-response and first aid teams were deployed across the city, Tuason said.
Classes in all schools were suspended as buildings were checked for damage, he said, adding that he had called an emergency meeting to deal with any contingency.
Officials of Masbate, about 350 kilometres southeast of Manila, led earthquake drills in schools and offices just last week after a magnitude-6.9 quake left 58 people dead, 60 others missing and displaced more than 200,000 on nearby Negros island on February 6.
The Philippines is in the so-called Pacific "Ring of Fire," where earthquakes and volcanic activity are common. The damage and casualties are compounded by poor construction in violation of building codes in the impoverished nation.
In 1990, a magnitude-7.7 quake killed nearly 2,000 people in northern Luzon region.
