Alert Level 2 up over Kanlaon as Phivolcs records consecutive quakes


And just a few hours later, the threat was raised again from two to three as Phivolcs warned of "hazardous eruption" within weeks or days as Mayon Volcano has exhibited "high unrest" and its magma is at the crater. This is the second phreatic eruption of Mayon which was recorded following a similar phenomenon which lasted for nearly two hours on Saturday afternoon.

Since the eruptions, a "faint crater glow" has been observed, and dramatic images sent in to show a bright red light being emitted from the mountain.

Mayon, one of the most active volcanoes in the country, first spewed ashes, which reached 2.5 kilometers (1.5 miles) in a phreatic eruption, lasting for nearly two hours on Saturday afternoon.

Based on the latest Phivolcs monitoring data, the volcano had another phreatic explosion at 8:49 a.m. Sunday.

Mayon's biggest eruption was in 1841, when lava flows buried a town, killing 1,200 people.

The seismological office urged the public not to enter the 6-kilometer radius Permanent Danger Zone (PDZ), where sudden explosions, rockfalls and landslides could occur. In case of ash fall events, which are most likely to affect communities on the western and southwestern flanks downwind of Mayon's crater, people should cover their nose and mouth with damp, clean cloth or dust mask. It last erupted in 2014, spewing lava and forcing thousands of people to evacuate. Civil aviation authorities must also advise pilots to avoid flying close to the volcano's summit as ash from any sudden eruption can be hazardous to aircraft.

Sto Domingo town mayor Herbie Aguas, on the other hand, ordered that residents within the slopes of the volcano who might be experiencing ashfalls should take precautionary measures against inhalation and possible roof collapse due to accumulated heavy ash and rain.

But Daep said those in evacuation centers may be allowed to return to their homes later in the day, unless Phivolcs raises the volcano alert level further. "Alert level 3 is what we consider critical, 4 is when eruption is imminent, and 5 is eruption in progress".
