“Kapag ganito po kalalim at ang magnitude ay magnitude 6, malapad po ang makakaramdam nito. … Mayroon naman tayong mga aftershocks na posibleng maramdaman,” Phivolcs Director Renato Solidum told ABS-CBN Teleradyo. 

(When the magnitude is this deep, magnitude 6, it could be felt widely. We could also expect aftershocks to be felt.)

The Philippines is situated on the Pacific "Ring of Fire," an arc of intense seismic activity that stretches from Japan through Southeast Asia and across the Pacific basin.
