Mt. Mayon spews white smoke, signals calming of the volcano – PHIVOLCS

ALBAY, Philippines — Today is the 32nd day since Mayon Volcano began erupting.
According to the Philippine Institute of Volcanology and Seismology (PHIVOLCS), Mt. Mayon has already spewed 82 million cubic meters of lava, the biggest volume since 1960.
Although it is not discounting the possibility of a huge eruption, PHIVOLCS said Mayon Volcano is slowly calming down.
PHIVOLCS based this information on the white smoke coming from the crater of Mt. Mayon.
The agency said the smoke billowing from the crater of Mt. Mayon is sulfur dioxide. As long as it continues to spew smoke, this means that nothing is blocking the magma, and thus, helps the lava to continuously flow. This PHIVOLCS said that is a sign that the volcano is beginning to calm down.
“Kung biglang bumagsak yung sulfur dioxide ibig sabihin blocked yung crater hindi makalabas yung gas it means nag build up siya ng pressure,” said PHIVOLCS Region 5 Spokesperson Paul Alanis
(If the sulfur dioxide stops coming out, this means the crater is blocked. The gas cannot go out, and it builds up pressure within.)
But the agency noted it’s not a sufficient basis to lower the alert level for Mayon Volcano.
In the past 24 hours, the agency recorded several episodes of lava fountaining that lasted for up to 20 minutes.
The lava flow reaches up to 4.5 km from the crater of the volcano.
More than 100 volcanic earthquakes, on the other hand, have already caused a series of rock falls.
The volcano is also continues to swell.
“Hindi po namin maibababa dahil again lahat ng parameters is matataas pa rin,” said the spokesperson.
(We could not lower it because again all the parameters remain high.)
PHIVOLCS is yet to determine the amount of lava that the volcano still has to release or when the eruption will end.
But with the white smoke it emits, the agency believes the threat of a possible massive eruption has already lessened. — Mon Jocson | UNTV News & Rescue
MANILA, Philippines — At past eight in the morning on Tuesday, the Philippine Institute of Volcanology and Seismology (Phivolcs) downgraded the alert status for Mayon Volcano to level 3.
This was due to the fewer recorded activities of Mt. Mayon.
“Mostly ang narerecord na lang natin ngayon, yung surficial events na rock falls, tapos yung mga low frequency events na associated lang sa degassing shallow surface,” Phivolcs senior science specialist Ed Laguerta said.
(What we have been recording mostly for now are surficial events such as rock falls and low-frequency events associated with the degassing shallow surface.)
With the downgrading of alert level for Mt. Mayon, the local government of Albay has allowed the return of 55,000 evacuees to their homes within the eight-kilometer danger around the volcano.
“Doon sa decampment, iko-consider pa rin namin yung post-disaster support na kailangang ibigay din sa kanila habang pinauwi na dahil syempre wala pa silang kabuhayan,” said Albay Public Safety and Emergency Management Office (APSEMO) head Cedric Daep.
(In terms of the decampment, we will still consider post-disaster support that we need to give them because they still have no livelihood.)
More than 2,000 families will remain at evacuation centers with homes within the 6-kilometer permanent danger zone and 7-kilometer extended danger zone.
This is while the alert status for the volcano has not yet been lowered down to level 2. — Mon Jocson | UNTV News & Rescue

MANILA, Philippines — The possible flowing of lahar from around the Mayon Volcano during the onset of the rainy season might hit 26 barangays in four towns of the province of Albay.
According to the Philippine Institute of Volcanology and Seismology (Phivolcs), the volcanic materials deposited around the Mayon Volcano might reach 90 cubic meters.
And once the rainy season comes, it might flow into the towns of Guinobatan, Camalig, Daraga, and Sto. Domingo.
This is why as early as now, the Mayon crisis management team has been asking officials of the said towns to prepare disaster plans in the event of a lahar flow.
Officials of the Office of the Civil Defense (OCD), Department of Environment and Natural Resources (DENR), Department of Health (DOH), Department of Social Welfare and Development (DSWD), and Department of Public Works and Highways (DPWH) are among the agencies that will outline the disaster plan.
The mayors target to submit their respective plans by next week.
Meanwhile, Phivolcs has recorded in the past 24 hours two incidents of lava fountaining as high as 150 meters and steam plumes reaching 100-600 meters high.
The agency also recorded seven lava-collapse-fed pyroclastic density currents or “uson“, 128 volcanic earthquakes and 12 rockfall events. — Joan Nano | UNTV News & Rescue
ALBAY, Philippines — The series of lava fountaining of Mt. Mayon last January on to February has reportedly damaged one part of the volcano’s crater.
The Philippine Institute of Volcanology and Seismology (Phivolcs) said that they are now closely monitoring the damaged crater that faces southeast or Legazpi City.
This has caused fear that the lava may flow to the direction of the city.
Phivolcs, however, assured that the lava will not reach Legazpi as it is situated 10 kilometers away from Mayon.
The agency said that the farthest that the lava can reach is 4.5 kilometers.
Phivolcs added that the said attrition or abrasion on Mayon’s crater helped them arrived at a more accurate conclusion as to where the lava will flow.
If Mayon’s mouth had still been intact, the agency will not be able to determine where the lava will flow in case of a strong eruption.
“Kung ito po ay nag-persist o hindi nagbago, maaari pong maapektuhan na ang iba pang bahagi ng bulkan (If this had persisted or did not change, other parts of the volcano would have been affected,” said PHIVOLCS volcano monitoring and eruption prediction division chief Mariton Bornas.
To date, Mayon is still on alert level 4.
However, its activities have been relatively weak and few and far between compared to last month. — Mon Jocson | UNTV News & Rescue
