Mayon residents return to evac centers due to Ruby threat


Barely a month after they were allowed to go home, residents of some areas near restive Mayon Volcano were brought back to evacuation centers, this time partially due to the threat of Typhoon Ruby (Hagupit).
 
Albay Governor Jose Salceda posted on his Facebook page Friday afternoon photos of residents from Barangay Maninila in Guinobatan town being brought back to the centers.
 
Salceda said these residents were brought back to the Guinobatan East Central School evacuation center.

 
 
Another batch of photos Salceda posted online showed soldiers helping the residents go back to the evacuation centers.

 
 
But he said the evacuation efforts will go full blast starting 8 a.m. Saturday.

 
 
Maninila was one of the barangays whose residents were allowed to decamp last November, after Mayon showed little activity for weeks.
 
Last Nov. 3, the Office of Civil Defense allowed residents in the seven- to eight-kilometer extended danger zone to return home for now.
 
On Nov. 4, many families whose homes were with in the seven- to eight-kilometer extended danger zone were allowed to go home.
 
Ruby threatens to make landfall in Eastern Visayas on Saturday, even as the Joint Typhoon Warning Center indicated it may hit Bicol and Metro Manila.
 
Lahar advisory
 
On Thursday, the Philippine Institute of Volcanology warned of heavy to intense rainfall from Ruby could induce landslides and lahar in volcanic edifices, particularly in Albay and Sorsogon provinces.
 
"In Albay Province, extreme rainfall may trigger landslides and excessive erosion of old pyroclastic deposits in the upper to middle slopes of Mayon Volcano, generating lahars in all river drainages. Potentially large-magnitude lahars can threaten downstream communities along river channels with inundation, burial and washout," it said.
 
Phivolcs added the greatest lahar hazard can consequently be faced by communities along the Masarawag (Guinobatan), Maninila (Guinobatan), Buyuan-Padang (Legaspi City), Lidong (Sto. Domingo), Mabinit (Legaspi City), Basud (Sto. Domingo), Miisi (Daraga), Anoling (Daraga) and Nabonton (Ligao City) Channels.
 
In Sorsogon Province, extreme rainfall may cause excessive erosion of existing pyroclastic deposits in the upper slopes of Bulusan Volcano, triggering lahar in rivers draining the southeastern, southwestern and northwestern flanks.
 
Potential moderate-volume lahars can threaten downstream communities along the Malunoy (Patag), Mapaso, Cadac-an, Tinampo and Cogon Rivers in Irosin and the Añog-Rangas River in Juban. — Joel Locsin/TJD, GMA News
