THE Philippine Institute of Volcanology and Seismology (Phivolcs) said aftershocks from the quake that struck nine kilometers southeast of municipality of Compostela may last for days or even weeks as it reminded those residing near the epicenter of the magnitude 6 earthquake to be vigilant of structures and tension cracks.
Phivolcs director Teresito Bacolcol, in the Laging Handa briefing Thursday, 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.
