Phivolcs monitors 2,491 aftershocks in Surigao del Sur after strong quake
MANILA, Philippines — State seismologists recorded almost 2,500 aftershocks following the 7.4 magnitude earthquake off Hinatuan Municipality in Surigao del Sur over the weekend.
The Philippine Institute of Volcanology and Seismology (Phivolcs) said that 2,491 aftershocks with strength ranging from magnitude 1.4 to 6.6 were logged in the province as of 7:00 a.m., December 5.
But only 29 of the 2,491 aftershocks were actually felt by the people in the area, Phivolcs noted.
State seismologists initially pegged the magnitude of the powerful temblor at 6.9, and later revised it to 7.4. The European Mediterranean Seismological Centre put the quake’s magnitude at 7.5.
The earthquake struck near Hinatuan at 10:37 p.m. on Saturday, December 2, triggering small tsunami waves off several provinces in Mindanao and islands of Japan.
Tsunami warnings in the Philippines were lifted on Sunday morning.
