MANILA, Philippines—A magnitude-6 earthquake shook parts of Mindanao Sunday night which was brought about by the movement of a trench beneath the sea off Sultan Kudarat.
However, the Philippines Institute of Volcanology and Seismology (Phivolcs) said there was no possibilities of a tsunami as the tectonic earthquake was too deep to trigger one. The quake had a depth of focus measured at 556 kilometers, the Phivolcs said.
Phivolcs science research assistant John Paul Fallarme told the Philippine Daily Inquirer that the earthquake shook portions of Mindanao at around 7:04 p.m. Sunday, with its epicenter at 195 kilometers southwest of Palimbang town in Sultan Kudarat. It was felt at Intensity III in Malita, Davao del Sur, and at intensity II in Davao City. Intensity III means many people inside their homes or buildings will feel the tremors and hanging objects can be seen swinging, but people outside may not feel the movement. Intensity II means a few people at rest or on the upper floors of tall buildings will feel the shaking.
A magnitude-6 earthquake is usually considered a strong earthquake that may cause considerable damage in a heavily populated area. Magnitude is the the amount of energy released by the earthquake.
