SUMMARY
On 13 January 2018 at 4:21 PM, Mayon Volcano generated a phreatic eruption (steam-driven) that propelled a grayish steam and ash plume approximately 2500 m high that was drifted to the southwest. Based on seismic records the activity lasted approximately 1 hour and 47 minutes.
Alert status was raised to level 4 (hazardous eruption imminent) on January 22 at 1:00 PM by DOST-PHIVOLCS due to the phreatomagmatic eruption (increased seismic unrest, lava fountaining and summit explosion).
