PHIVOLCS: Steam, sulfur dioxide emissions monitored at Mayon but no magmatic eruption imminent

(Eagle News)–Steam and sulfur dioxide  emissions were  monitored at Mayon in 24 hours.

No volcanic quake was monitored at the volcano, which remains on alert level 1, the Philippine Institute of Volcanology and Seismology said.

According to PHIVOLCS, the steam-laden plumes  downslope were moderate.

Sulfur dioxide  emission was last measured at an average of 143 tons  on  October 10.

A slight inflation of the edifice and inflation of the lower to middle slopes since July 2019 to present were also recorded, PHIVOLCS said.

PHIVOLCS said that at alert level 1, the volcano is at an abnormal condition.

Although this means that  no magmatic eruption was imminent, PHIVOLCS reiterated the ban on the entry  into the 6-kilometer radius Permanent Danger Zone due to the dangers of rockfalls, landslides and avalanches at the middle to upper slope, sudden ash puffs and steam-driven or phreatic eruptions from the summit.”

PHIVOLCS said active stream and river channels and those identified as “perennially lahar-prone areas on all sectors of the volcano” should also be avoided especially during extreme weather conditions when there is heavy and prolonged rainfall.

“PHIVOLCS maintains its close monitoring of Mayon Volcano and any new development will be communicated to all concerned stakeholders,” it said.
