The Albay Public Safety and Emergency Management Office (APSEMO) yesterday morning said the Mayon Volcano seismic network detected four volcanic earthquakes and four rockfall-related events during the past 24-hour observation period.
The volcano alert status remains at Alert Level 1, which means that it is at abnormal condition, APSEMO head Dr. Cedric Daep said.
In its advisory, Mayon Volcano Bulletin No. 1, the APSEMO said it also observed moderate emission of white steam plumes.
It added that it has measured the sulfur dioxide flux at an average of 487 tons/day since May 6.
“Although this means that presently no magmatic eruption is imminent, it is strongly advised that the public refrain from entering the six-kilometer-radius permanent danger zone due to the perennial life-threatening dangers of rockfalls, landslides/avalanches at the middle to upper slope,” Daep added.
