Albay: The Philippine Institute of Volcanology and Seismology (PHIVOLCS) on Thursday raised the alert level of Mayon Volcano in Albay province on Luzon island following signs of increased volcanic activity. The PHIVOLCS said the escalation from alert level 1 (low-level unrest) to alert level 2 (increasing or moderate level of unrest) indicates that magma is moving beneath the volcano, increasing the likelihood of sudden explosive activity.According to Namibia Press Agency, the institute noted that current unrest is driven by shallow magmatic processes, which could result in a hazardous magmatic eruption. PHIVOLCS issued an advisory emphasizing the importance of vigilance and cautioned the public against entering the six-kilometer-radius Permanent Danger Zone. This restriction is essential to minimizing risks from potential explosions and related hazards.Mayon Volcano, known as the country's most active volcano, has a long history of eruptive activity, underscoring the importance of these precautionary mea sures.
