LEGAZPI CITY (Jan 22) - Intensified lava flow was voluminously flowing than before feeding the advancing Miisi lava flow anew and feeding two new lava flows was observed on the Bonga Gully and upper Buyuan watershed.

This was disclosed by Paul Alanis-Science Research Specialists of the Philippine Institute of Volcanology and Seismology (PHIVOLCS) in a press briefing here Monday. He said that the two high-lava fountains that occurred 10:45 PM Jan. 21 and 2:25 AM Jan 22 signified an increase in mass eruption rate and ash plumes rose about 1,300 meters above the summit. The ash plumes were drifted southwest and ash fall was experience in Barangays of √ďas, and Guinobatan. Currently, the Miisi lava flow has advanced beyond three (3) kilometers from the summit crater well within the Permanent Danger Zone (PDZ).

Alanis said that Alert Level 3 remains in effect over Mayon Volcano, which means that it is currently still in a relatively high level of unrest and hazardous eruption is still possible within weeks or even days. The public is strongly advised to be vigilant and desist from entering the six (6) kilometer-radius Permanent Danger Zone (PDZ) and the 7-km Extended Danger Zone (EDZ) on the southern flanks due to the danger of rockfalls, landslides and sudden explosions or dome collapse that may generate hazardous volcanic flows. Increased vigilance against pyroclastic density currents, lahars and sediment-laden streamflows along channels draining the edifice is also advised. (Mar de la Cruz)
