A magnitude 6.0 quake that struck central Mindanao damaged roads and caused patients to flee a hospital in Lanao del Sur Wednesday morning.
The inland tremor struck 6 kilometers west of Wao in Lanao del Sur at a depth of 1 kilometer at 5:21 a.m, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).
Based on the initial assessment of Francis Garcia, Municipal Disaster Risk Reduction Management Officer in Wao, an estimated 30 homes from Barangay Extension, Siran, Panang and Balatin sustained partial damage from the quake.
Four homes were also totally damaged in Barangay Panang.
The Panang National High School and two mosques in the area were also damaged.
Residents said the quake opened up cracks, estimated at four inches in width and 12 inches in depth, along the National Highway.
Meanwhile, doctors, nurses and patients rushed out of the Wao District Hospital into a clearing after the quake struck.
The tremor was also felt in the nearby barangay of Wadya in Banisilan, North Cotabato.
Photos showed canned goods and other items scattered on the floor of a sari-sari store after the tremor.
Aside from Cotabato City, intensity IV was also felt in Davao City, Cagayan De Oro City and Gingoog City.
Phivolcs said the quake is expected to cause damage and trigger aftershocks. It said it has received reports of residents panicking in several areas due to the temblor.
"We had reports that there were panicking and brownouts in Cotabato City," Phivolcs research specialist Janila de Ocampo said in a phone interview. With reports from Maricel Butardo and Francis Magbanua, ABS-CBN News
