MANILA - A magnitude 5 aftershock hit Cotabato on Saturday morning, state seismology agency Phivolcs said.
The shock happened at 6:52 a.m. southeast of the municipality of Tulunan.
It had a depth of 12 kilometers and was tectonic in origin.
Phivolcs said the movement was an aftershock of the magnitude 6.3 earthquake that hit Cotabato last Wednesday, October 16.
The powerful quake that was almost felt in the entire Mindanao island has claimed the lives of at least 5 people and damaged several homes and buildings.
Intensity IV was felt in Kidapawan City; Intensity III in Tupi, Koronadal City and Tampakan, South Cotabato; and Intensity II in General Santos City.
Meanwhile, instrumental intensities were reported in the following areas:
Koronadal City, South Cotabato
General Santos City
Tupi, South Cotabato
Phivolcs said no damage is expected from this aftershock.
On Friday, Phivolcs Associate Scientist Dr. Teresito Bacolcol said they had recorded around 400 aftershocks since Wednesday's quake. The strongest one was magnitude 5.5.
Bacolcol allayed fears on the perceived frequency of tremors, adding that Phivolcs records some 20 earthquakes daily.
