Two moderate earthquakes struck the provinces of Zambales and Davao Oriental on Wednesday morning, according to the Philippine Institute of Volcanology and Seismology (Phivolcs).
In its bulletin, the agency said the first quake with a magnitude of 3.2 occurred at 4:33 a.m. with its epicenter traced at 22 kilometers southwest of San Antonio in Zambales.
Phivolcs said the tectonic quake has a depth of 27 kilometers.
At 5:11 a.m., another tremor with a magnitude of 3.8 hit Davao Oriental.
Its epicenter was estimated 125 kilometers southeast of Governor Generoso in Davao Oriental.
The quake, which was also tectonic in origin, had a depth of 194 kilometers.
Phivolcs said no reported casualty nor damage to property from both tremors.
It added that no aftershocks were also expected from the said quakes.
Phivolcs earlier said that an average of 20 earthquakes hit the country daily since the Philippines lies on the Pacific Ring of Fire, where earthquakes and volcanic eruptions are frequent due to friction between shifting tectonic plates.
However, the agency noted that most of these tremors are imperceptible. PNA
