More aftershocks possible from Surigao earthquake

More aftershocks are possible from the magnitude 5 earthquake that struck 9:06 a.m. Thursday (Dec. 15) below waters off Surigao del Norte province's Burgos municipality.

Philippine Institute of Volcanology and Seismology (Phivolcs) warned about such possibility, recording that offshore earthquake's first aftershock as reaching magnitude 3.5 at 9:31 a.m. Thursday.

"The earthquake can trigger further aftershocks," said Phivolcs science research assistant Leni Salayon.

She noted Phivolcs is not expecting damages from the earthquake.

According to Phivolcs, Thursday's earthquake was of tectonic origin and struck at a depth of 32 kms.

"Movement of the Philippine Trench triggered that earthquake," said Salayon.

Philippine Trench is among the country's active geologicformations, she noted.

Phivolcs said the earthquake was reported at intensity IV in Burgos as well as intensity III in Surigao City and Southern Leyte province's Hinunangan municipality.
