(UPDATE) A MAGNITUDE 6 earthquake jolted several towns in Surigao del Norte and the Caraga Region (Region 13) in Mindanao on Friday, a week after two powerful quakes hit the country. The Philippine Institute of Volcanology and Seismology (Phivolcs) said the quake struck at 7:03 a.m. near General Luna town, Surigao del Norte. It had a depth of 28 kilometers (km). The quake was initially recorded at magnitude 6.2, with a depth of 10 km, according to Phivolcs Director Teresito Bacolcol in a radio interview. It was later recalibrated to 6.0. The quake was felt at Intensity 5 in the towns of Basilisa, Cagdianao, Dinagat and San Jose on the Dinagat Islands and Claver in Surigao del Norte. It was Intensity 4 in Butuan City, as well as the towns of Anahawan, Hinunangan, Hinundayan, Liloan, Pintuyan, Saint Bernard, San Francisco, San Juan, San Ricardo and Silago in Southern Leyte; Libjo and Tubajon on Dinagat Islands; and the City of Surigao in Surigao del Norte. It measured Intensity 3 in Tacloban City, Abuyog, Dulag and Palo in Leyte, as well as in Nasipit, Agusan del Norte. Phivolcs said the quake was also felt in Cagayan de Oro City and Davao City. Several aftershocks were recorded, ranging from magnitude 1.2 to 4.4, including a 4.2 earthquake around noon time near Burgos, Surigao del Norte. There were no immediate reports of casualties or damage, provincial rescuer Ralph Cadalena told Agence France-Presse (AFP). “We felt a sudden strong shake, but it was only for a very short time,” Cadalena said. It came a week after two quakes of 7.4 and 6.7 magnitude shook the eastern section of Mindanao, killing at least eight people. These followed a magnitude 6.9 earthquake days earlier that killed 76 people and destroyed or damaged 72,000 houses in Cebu province. Earthquakes 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. An 8.0-magnitude quake off Mindanao island’s southwest coast in 1976 unleashed a tsunami that left 8,000 people dead or missing, the country’s deadliest natural disaster.
