MANILA, Philippines — State volcanologists warned Saturday that heavy rains “could generate channel-confined lahars and sediment-laden streamflows in the channels” of Mayon volcano.
At a Laging Handa public briefing on Friday, Mayon Volcano’s resident volcanologist, Dr. Paul Alanis, warned residents near the volcano to be on the lookout for the possibility of a lahar.
“In Albay, pinapaalalahanan natin anging mga kababayan nakatira malapit sa ilog nagmumula sa Mayon Volcano na maghanda and maging alert [dahil] maaaring magkaroon tayo ng lahar,” Alanis said.
(In the province of Albay, we remind our compatriots who live near the river that comes from the Mayón Volcano to prepare and be alert [because] we can have a lahar.)

Phivolcs also reported that a very slow outpouring of lava was continuing from the summit crater. He said the lava flows have now advanced to approximate lengths of 2,800 meters along the Mi-isi ravine and 1,400 meters along the Bonga de Mayon ravine.
Phivolcs also noted that debris from the collapse has been deposited 4,000 meters from the crater along the Basud channel.
The riot indicators were marked even more from 5 a.m. state volcanologists.
Mayon volcano is still under alert level 3 as a dangerous eruption is possible within weeks or even days, Phivolcs said.
