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 2,500 meters high that was drifted to the southwest. Based on seismic records the activity lasted approximately 1 hour and 47 minutes.

Characterized by a general decline in unrest reflected by moderate seismicity and degassing, deflation of the edifice, and a decrease in eruptive activity at the summit crater, the Alert Level of the volcano has been downgraded to Level 3 on 06 March 2018.
