Mount Mayon Spews 500-Meter Ash Plumes Twice
The famous Mount Mayon in the province of Albay spews 500-meter grayish-white ash plumes above the summit, according to Phivolcs.
On Monday morning (November 26, 2018), the Philippine Institute of Volcanology and Seismology (Phivolcs) announced that Mount Mayon produced phreatic eruptions.
The popular Philippine volcano alleged spews 300 to 500-meter ash plumes above its summit before drifting to the southwest direction.
The volcanology agency recorded the two steam-driven eruptions between 7:59 and 8:05 am then raise Mt. Mayon under alert level 2.
“The events generated grayish to grayish white ash plume that rose 300 to 500 meters above the summit before drifting southwest,” Phivolcs said.
Phivolcs also prohibits the public to enter the 6-kilometer radius permanent danger zone and the 7-kilometer extended danger zone along Camalig town to Barangay Sta. Misericordia, Sto. Domingo.
Phreatic eruptions are usually steam-driven and frequently exist when water under the ground was heated by hot rocks, lava, magma, or new volcanic deposits.
The seismology agency also advised aircraft to avoid flying close to Mayon Volcano’s summit.
