MANILA, Philippines — Mayon Volcano in Albay continued to spew pyroclastic materials yesterday as authorities maintained the eight-kilometer danger zone.
At least 11 episodes of lava collapse pyroclastic density current events were observed between 8:51 a.m. on Thursday and 2:01 a.m. yesterday, the Philippine Institute of Volcanology and Seismology (Phivolcs) said in its bulletin.
The volcanic materials were deposited along the Miisi, Basud and Bonga gullies within two kilometers of the summit crater.
The Miisi and Bonga-Buyuan lava flows have advanced to 3.2 kilometers and four kilometers, respectively, from the crater, Phivolcs said.
A total of 338 volcanic earthquakes were recorded in the past 24 hours.
Sulfur dioxide gas emission was measured at an average of 3,066 tons per day on Thursday.
Phivolcs said the volcano remains under Alert Level 4, which means that a hazardous eruption could still occur within days.
The agency reiterated its warning to the public against entering the extended danger zones due to continued pyroclastic density currents, lahar and sediment-laden stream flows along channels draining the edifice.
Scientists said Mayon, which has been erupting for almost two weeks, still appears to be swelling with magma beneath the surface.
More than 80,000 residents of Albay have been displaced by the volcano’s eruption.
