MANILA - An official of the Philippine Institute of Volcanology and Seismology (Phivolcs) has reminded those residing near the epicenter of the magnitude 6 earthquake that jolted Davao de Oro Wednesday to be cautious of structures and tension cracks.
In the Laging Handa briefing Thursday, Phivolcs director Teresito Bacolcol said aftershocks from the earthquake that struck 9 kilometers southeast of the municipality of Compostela may last for days or even weeks.
Bacolcol said Phivolcs is expecting small to moderate aftershocks to occur near the epicenter.
"The public is advised to be cautious of the structures that (were) visibly weakened as a result of the earthquake last night. If your house has cracks, refrain from entering it for the meantime. Consult your municipal or city engineering office for advice," he said.
Bacolcol said people around the mountainous areas near the earthquake's epicenter should check the slopes for tension cracks.
These cracks may cause landslides so people should be prepared, he said, adding that "In case of another strong earthquake, do the duck, cover and hold."
As of 2 p.m. Thursday, Phivolcs logged 383 aftershocks from the magnitude 6 earthquake. At least 59 of these were plotted or located, and one was felt.
Aftershocks ranged in magnitude from 1.3 to 3.6.
Bacolcol said there is no tsunami threat due to the earthquake.
"There is fake news spreading, causing fears among the public, saying the earthquake would generate a tsunami. Don't believe that," he said.
The earthquake occurred inland thus no tsunami could be generated, he added.
Phivolcs' Davao station continues to gather data. A group from the main office in Quezon City will visit the quake's epicenter on Friday to evaluate the impacts of the earthquake, Bacolcol said.
Meanwhile, no damage was reported in the airports after a magnitude 6 earthquake jolted Davao de Oro on Wednesday, the Civil Aviation Authority of the Philippines (CAAP) has confirmed.
Based on initial assessments, the Davao International Airport's runway, buildings, and structures did not incur any damage from the earthquake, CAAP spokesperson Eric Apolonio said Thursday.
The Mati Airport in Davao Oriental also reported no damage in its passenger terminal building.
Apolonio said a light tremor was felt at the Laguindingan Airport but there was no reported damage in its facilities.
The General Santos International Airport, on the other hand, reported normal operations, he said. (PNA)
