BUTUAN CITY – A 4.3-magnitude earthquake jolted Bukidnon province Saturday dawn, April 13, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
In its bulletin, Phivolcs said the earthquake was recorded at 12:20 a.m. with its epicenter traced five kilometers southeast of Pangantucan town. It had a shallow depth of only one km, the state agency said.
Intensity 5 was recorded in the town proper of Pangantucan, while Intensity 4 was registered in nearby Kalilangan and Maramag towns, also of Bukidnon province.
In its instrumental intensity, Phivolcs also recorded intensity 2 in Cagayan de Oro City.
Meanwhile, in its latest bulletin, Phivolcs also registered a magnitude-4 tremor at 3:45 a.m. on the same day.
The epicenter was traced 23 km northeast of Pacific Ocean facing town of Burgos, in Siargao Island, Surigao del Norte province.
The latest tremor in that island had a shallow depth of only 8 km, Phivolcs said.
No aftershock or tsunami alert was raised by the state agency.
The two tremors that struck early Saturday morning in Bukidnon and Siargao Island were both tectonic in origin, Phivolcs added.
The provincial disaster risk reduction and management councils there also reported no damage or injury.
The Philippines lies in the Pacific “Ring of Fire”, where colliding plates in the Earth’s crust cause frequent earthquakes and volcanic activity.
