MANILA, Philippines — The magnitude 7.4 earthquake that happened off the coast of Hinatuan in Surigao del Sur on Saturday was caused by movements in the Philippine trench, said Philippine Institute of Volcanology and Seismology (Phivolcs) Director Teresito Bacolcol on Sunday.

The quake happened at 10:37 p.m. on Saturday, December 2.

The state seismologist raised a tsunami alert following the quake but took it down early Sunday.
