A 6.9-magnitude quake struck off the coast of central Philippines on Tuesday evening, the US Geological Survey said, with no immediate reports of casualties or damage.

The local seismology office warned of a possible "minor sea-level disturbance" and urged residents of the central islands of Leyte, Cebu and Biliran to "stay away from the beach and not to go to the coast."

The epicentre of the quake was around 11 kilometres (seven miles) east-southeast of Calape, a municipality in Bohol province with a population of around 33,000 people.

The USGS had reported a magnitude reading of 7.0, before revising it down.

The Pacific Tsunami Warning Center said "there is no tsunami threat from this earthquake" and "no action is required."

Quakes are a near-daily occurrence in the Philippines, which is situated on the Pacific "Ring of Fire", an arc of intense seismic activity stretching from Japan through Southeast Asia and across the Pacific basin.

Most are too weak to be felt by humans, but strong and destructive ones come at random, with no technology available to predict when and where they might strike.

At least 34 people, including two babies were killed when a contraband fuel depot exploded into flames in southern Benin near the border with Nigeria on Saturday.

According to Beninese Interior Minister Alassane Seidou, “a serious fire occurred in the town of Seme Podji. Another 20 people were seriously wounded in the incident.”

"I can't really give you the cause of the fire, but there is a large gasoline warehouse here and cars, tricycles and motorcycles come from morning to evening,” he added.

Nigeria is a main oil and gas producer where fuel smuggling is very common along its borders, particularly when the government maintains a subsidy to keep fuel prices low.

The majority of the victims were burnt and they could not be not be identified.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
