LEGAZPI CITY: The provincial government of Albay is still bracing for another natural calamity after the Philippine Institute of Vocanology and Seismology (Phivolcs) recorded an increased number of earthquakes in areas surrounding the Mayon volcano.
According to Phivolcs, its seismic monitoring network recorded 14 volcanic earthquakes and six rockfall events for the past 24 hours on Tuesday.
It explained that the increasing number of volcanic earthquakes is a sign that magma is moving towards the rim of Mayon’s crater. The movement of magma might prompt the volcano to erupt anytime soon, according Phivolcs.
In light of the cited observations, Phivolcs strongly recommended that the 6-kilometer (km) Permanent Danger Zone (PDZ) around the volcano and the 7-km Extended Danger Zone from the southeastern flank of Mayon be strictly enforced.
Phivolcs warned of rock falls, landslides, and sudden explosions or dome collapse that might cause hazardous lava flows.
Despite the increased activity observed from Mayon, Phivolcs said the alert level status of the volcano remained at alert level 3.
On October 15, Phivolcs hoisted the alert level status of Mayon volcano from level 2 to level 3 following increased seismic activities.
More than 2,000 families or 10,000 people residing within the 6-km PDZ are still staying in evacuation centers.
