Phivolcs logs 54 aftershocks following 6.8-magnitude Surigao quake
MANILA, Philippines — At least 54 aftershocks rocked Surigao del Sur early Monday, following the magnitude 6.8 earthquake off Cagwait Municipality, state seismologists reported.
Of the 54 aftershocks, the Philippine Institute of Volcanology and Seismology (Phivolcs) said that only 13 were recorded with magnitudes ranging from 1.8 to 5.6.
Phivolcs: This is a different event
The tectonic tremor struck 63 kilometers east-southeast of Cagwait at 3:49 a.m. with a shallow depth of focus of one kilometer, state seismologists said.
Like the strong magnitude 7.4 earthquake off Hinatuan town in the same province over the weekend, Phivolcs said the latest magnitude 6.8 temblor was triggered by the Philippine trench.
However, Phivolcs told reporters that “this is a different event” from the magnitude 7.4 tremor and not an aftershock.
