There were no casualties from the 1984 eruption because more than 73,000 people evacuated the danger zones as recommended by scientists of the Philippine Institute of Volcanology and Seismology.

MANILA (Mabuhay) — Mayon Volcano is showing more signs of activity, the Philippine Institute of Volcanology and Seismology (Phivolcs) said on Friday.

Phivolcs said 9 volcanic quakes and 6 rockfall events have been recorded over the past 24 hours, although that is still lower compared to last week.

A weak to moderate emission of white steam plumes drifting southwest was also observed.

Phivolcs added the volcano is still swollen, and registering high sulfur dioxide levels, indicating a state of unrest.

Officials said the permanent danger zone around the volcano should be enforced due to the danger of rockfall, landslides, and sudden explosions or dome collapse that may generate hazardous volcanic flow.

Alert Level 3 remains in place, which means an eruption could take place within weeks.

Phivolcs is looking at two scenarios, either the volcano stays quiet weeks before erupting like it did in 1984, or it could take months before an actual eruption takes place.

The local government of Albay is appealing for more help as some 11,000 evacuees remain in evacuation centers with no definite time frame for returning home. (MNS)
