The US Geological Survey reports Saturday a 5.7-magnitude earthquake struck just off the northern tip of the island of Luzon in the Philippines.
The moderately strong temblor hit the Babuyan Islands region Saturday afternoon at 1636 GMT, (Sunday morning 12:36am, local time at the epicenter) approximately 78 miles NNE of the city of Laong in the northern Philippines.
According to the USGS’ report, the Philippine quake’s epicenter had a depth of 15.8 miles (25.5 kilometers) and was about 317 miles (511 kilometers) north of the capital city of Manila.
The Pacific Tsunami Warning Center has not issued any warnings or advisories and at the time of this writing there are no immediate reports of injuries or damage.
The Philippines sits on the Pacific Ring of Fire — a belt around the Pacific Ocean dotted by active volcanoes and unstable ocean trenches.
One fault line runs directly under Manila, a metropolis of more than 12 million people, and government seismologists have warned the city is unprepared for a major earthquake.
