Share TweetBy Ellalyn De Vera-RuizThree days after the 6.3-magnitude earthquake hit Mindanao last Wednesday, more than 600 aftershocks have been recorded by the Philippine Institute of Volcanology and Seismology (Phivolcs). According to Phivolcs science research specialist Dante Soneja, 663 small-to-strong magnitude aftershocks have been documented as of 8 a.m. Sunday. Of this number, 324 were plotted from their original source, which is Tulunan, North Cotabato, while only 27 were felt. Phivolcs said the destructive earthquake was generated by the movement of a northwest-trending strike-slip fault in Tulunan.
