Three mild earthquakes hit Baguio City Wednesday, Philippine Institute of Volcanology and Seismology (Phivolcs) said.
A magnitude 3.0 earthquake was recorded 11:34 a.m. It was followed by a magnitude 2.4 earthquake recorded at 11:37 a.m.
Another slightly stronger magnitude 2.5 earthquake hit the city at 1:08 p.m.
Intensity II was recorded in Baguio City during the 1st earthquake. The two other tremors were not felt in the city.
All earthquakes are tectonic in origin.
According to Bhenz Rodriguez, science research assistant of Phivolcs, the activation of Pugo Fault may have caused the tremors.
He added that the movement of fault lines is normal.
"Normal naman sa mga fault na magkaroon ng mga earthquake," he said.
(It is normal for fault lines to cause earthquakes.)
He also said residents should not worry about the tremors. However, they should always be prepared for any disasters.
No aftershocks or damage are expected from the earthquakes, PHIVOLCS said.
