MANILA—A series of aftershocks continued to rock southern Mindanao, following Wednesday's 6.3-magnitude earthquake that left 5 people dead and dozens injured.
State seismologists have recorded at least 5 light to moderate aftershocks that occurred southeast of Tulunan town in North Cotabato.
The Philippine Institute of Volcanology and Seismology (Phivolcs) reported that a 4.5-magnitude aftershock struck Tulunan at 1:50 a.m. Friday.
Earlier, a 4.8-magnitude aftershock took place at 11:05 p.m. Thursday.
Intensity 4, which may feel like the passing of a heavy truck and cause hanging objects to swing considerably, was recorded in Kidapawan City, North Cotabato.
Another 2 aftershocks, measuring 4.7 and 5.2 in magnitude, were also recorded on Thursday at 9:53 a.m. and 2:18 p.m.
A 4-magnitude aftershock also occurred at 9:24 p.m. Wednesday, hours after the shock of the 6.3-magnitude tremor.
The Philippines is in the geologically active Pacific Ring of Fire and experiences frequent earthquakes.
Phivolcs director Renato Solidum earlier warned residents in Mindanao to be on the lookout for possible landslides.
"Steep areas, especially those that experienced intensity 7 and 6 shaking, there could be landslides during aftershocks or heavy rains," he said.
