5.6-magnitude quake jolts Mindanao coast
Most are too weak to be felt by humans, but strong and destructive quakes come at random with no technology available to predict when and where they will happen
A magnitude 5.6 earthquake struck off the southern Philippines on Wednesday, the United States Geological Survey (USGS) said, with no immediate reports of damage or casualties.
The quake off the coast of the island of Mindanao had a depth of 30 kilometers (18.6 miles), the USGS added.
The Philippine Institute of Volcanology and Seismology placed the epicenter about 43 kilometers southwest of the town of Maitum, located in a mountainous and sparsely populated area.
Local authorities told AFP early indications were that the quake had caused no significant damage.
“It was strong but didn’t last long. We have checked but it was negative (for damage or casualties),” said Gilbert Rolifor, a fire department official in Maitum.
Quakes are a daily occurrence in the Philippines, which sits along the Pacific “Ring of Fire," an arc of intense seismic and volcanic activity that stretches from Japan through Southeast Asia and across the Pacific basin.
Most are too weak to be felt by humans, but strong and destructive quakes come at random with no technology available to predict when and where they will happen.
