Mayon less violent but big bang still possible —Phivolcs

A giant mushroom-shaped cloud rises into the air from the Mayon volcano, seen from the highway in the town of Camalig, near Legazpi City in Albay province, south of Manila on January 22, 2018. The giant mushroom-shaped cloud shot up from the Philippines' most active volcano on January 22, witnesses and authorities said, darkening the skies and raining ash on communities where tens of thousands have fled an impending eruption. / AFP PHOTO / -

Volcanic activity on Mayon has become less intense compared to last week but the Philippine Institute of Seismology and Volcanology (Phivolcs) said a more violent eruption could still take place.

Phivolcs director Renato Solidum said the height of the ash plumes that Mayon generated over the past days were lower compared to the first days when it erupted.

“Usually mga two kilometers lang. Hindi ito kasing taas compared sa mga naunang ash plumes noong first days ng week,” Solidum said in an interview with Radyo Inquirer 990 AM.

“Saka may pause noong Friday afternoon to Saturday evening. Mga 28 hours na walang lava fountaining activity,” he added.

On Jan. 22, the Phivolcs recorded a five-kilometer high ash plume and a 700-meter high lava fountain episode that forced the agency to immediately raise to alert level of Mayon to four.

Despite the decrease in height of its ash columns, Solidum said Mayon’s crater continued to swell, leaving the possibility of a destructive explosion.

“Hindi pa natin masasabi na humihina. Visually, parang humihina pero actually patuloy ang paglabas ng lava,” Solidum said.

“Ang scenario na ating tinitingnan ay possibleng ganyan lang ang ipinapakita ng volcano until maubos yung kanyang dapat ilabas. O di kaya ay magkaroon ng mas malalakas pang pagsabog kesa sa kasalukuyan kung makaipon ng gas sa loob ng bulkan,” he added. /cbb
